The role of healthy lifestyle in strengthening pupils` health – the basics of human life-sustaining activity
Annotation:

This article mainly deals with the role of healthy lifestyle in strengthening pupils` health. The relevance of the issue of healthy lifestyle modeling arises out of the fact that heath is one of the most significant life values of a person and a guarantee of his or her welfare longevity. Currently, due to the low life expectancy of people, it is crucial to foster the meaning of health as the main value in one`s life and importance and necessity of health preservation from the early childhood. Life preservation requires dedicated and persistent efforts from every person. Herewith, it is necessary to understand one fact: life preservation is a personal prerogative. If one is to always be healthy one must remember that it requires persistent, dedicated and considerable efforts. Therefore, it is crucial to have a long course of personal conduct that designates the general culture of our labour and rest management, rational combination of physical and mental workload, sensible nutrition, active leisure and good quality sleep, and, moreover, skills of safe conduct in different dangerous emergencies. All of it composes the system of healthy lifestyle.

Influence of ultrasonic treatment on the efficiency of biogas production
Annotation:

This paper presents the results of the influence of ultrasonic treatment in the cofermentation of the cattle manure mixture (cattle) with the leaven from the rumen of ruminants on the process of biogas production. Anaerobic digestion was carried out in matinence periodic operation at the mesophilic temperature of 38 C ̊. As a substrate, a mixture with a content of 70 % cattle manure and 10 % leaven from rumen of ruminants was used. Treatment with ultrasound of the mixture was carried out at an intensity of 10 W/cm2 and an amount of input energy of 9350 kJ/kg of dry matter (DM), which completely eliminated the processes of stratification and sedimentation. Decomposition of organic matter (OM) in the periodic regime with the enzyme and ultrasound treatment occurred within 8 days, the usual substrate during this time OM decomposed 3.0 times less (only 14 %). The process of fermentation of methane in continuous and periodic modes treated with ultrasound, as at other temperatures, was stable, as can be judged by the values of volatile fatty acids (VFA) Volatile fatty acids (VFAs), alkalinity, pH, and biogas. The energetical efficiency of methane fermentation is estimated by comparing the volume of fuel (biogas) and heat consumption for technological needs. As shown by the comparison of efficiency of different regime, the largest amount of commercial energy in the form of biogas was obtained in the mode of joint fermentation of a mixture of cattle manure (cattle) with a ferment from the rumen of ruminants treated with ultrasound – 3 times more than without treatment (space).

The study of nutritional values and organoleptic properties of poly-grain extruded mixture
Annotation:

Among many environmental conditions that affect a person, the most important factor is nutrition. Today, there is no doubt that there is a direct link between nutrition, health and disease. Proper nutrition ensures normal growth and development of a person, contributes to the prevention of diseases, has a positive impact on life expectancy and creates conditions for adaptation to the environment. A very actual topic for public catering in the Republic of Kazakhstan, namely for fast food companies, is the development of new recipes and culinary products from relatively inexpensive vegetable raw materials, as well as qualitatively new food products with a purposefully changed chemical composition. One of the main ways of solving problems of expanding the production of products for quick service, as well as products for dietary and therapeutic and preventive nutrition is the use of sprouted grains and beans. In this article, poly-grain mixtures of sprouted wheat and extruded soy beans in different ratios are studied and considered. Poly-grain mixtures developed by us are balanced in nutrients, vitamins and amino acids. The research was carried out on the basis of the accredited testing laboratory of RUBICOM enterprise LLP and the scientific laboratory of the Innovative Eurasian University. The purpose of this work is to study a promising method for increasing the nutritional value of grain mixtures by extruding them at different temperature conditions. To achieve this goal, the following tasks were planned: – to study the grain of soy beans and sprouted wheat on the organolepti c characteristics and chemical composition of the poly-grain mixture; – examine the chemical composition of the poly-grain mixture before extrusion; – choose the optimal mode of the extrusion process; – study and analyze the chemical composition of poly-grain extruded mixture; It should be noted that we have developed for the first time the optimal technological mode of extrusion of poly-grain mixture from sprouted wheat and soy beans, and the physical and chemical composition of the poly-grain mixture was studied. The results of the research presented in this paper are the basis for the development of recipes and technologies for fast food products. The reliability and validity of scientific statements is confirmed by the choice of modern methods of chemical composition analysis.

New format of relations in public procurement of the Republic of Kazakhstan in connection with the pandemic COVID-19
Annotation:

In this article, the author examines the problems of legal regulation of public procurement in a state of emergency and quarantine measures. The purpose of this article is to study the changes that have appeared in the legislation of the Republic of Kazakhstan in connection with the introduction of the state of emergency and quarantine in the country. The author provides a legal assessment and analyzes the new norms of Kazakhstani legislation regulating public relations in the field of organizing public procurement. The closure of state borders, the violation of the usual, accumulated over the years, economic ties led to disruptions in the economic activities of state bodies. With all the disadvantages that took place, the positive factor was that the demand for the goods of Kazakhstani producers on the market increased. The introduced new method of public procurement using framework agreements made it possible, in turn, to ensure the guaranteed sale of products of Kazakhstani commodity producers, and also made it possible to apply import substitution of frequently purchased goods. In this article, the author, on the basis of a study of the current practice in this area, demonstrates the features of legal regulation of the sphere of public procurement in completely social new conditions with the help of novelties in legislation, and also reveals the features of the operation of legal norms regulating the sphere of public procurement of goods, works and services in conditions of a state of emergency and quarantine measures. The adoption of special measures by the Government of the Republic of Kazakhstan made it possible to transfer financial and economic relations in the state to a new format – "customer-supplier". The measures taken by the government have now been extended until the end of 2020. These measures on the part of the Government of the Republic of Kazakhstan made it possible to introduce a sparing legal regime for regulating this area for representatives of medium and small businesses, in order to minimize the losses of the latter arising against the background of the introduction of a state of emergency and quarantine measures. Taking into account the analysis of judicial practice in the consideration of cases on public procurement, the author emphasizes that in conditions of quarantine measures in Kazakhstan, as a rule, there are violations of the same type, both on the part of customers and on the part of suppliers.

On some aspects of the project-based approach in the context of increasing the efficiency of economic development
Annotation:

The article discusses various aspects of project management, which is one of the most effective tools and allows you to skillfully take into account various factors, as a result of which the reliability of implementing successful changes and achieving goals in all types of professional activities increases. In Kazakhstan, project management dates back to the 1990s, but the real practical application of this management tool is observed at the beginning of this century. According to the authors, one of the key problems of widespread implementation and use of the project approach in the private and public sectors is the lack of information and methodological support for the development of this area. The purpose of this study is to systematize the theoretical and methodological aspects of project management in the context of improving the quality and efficiency of economic decisions. Any project is a change that is caused by the creation of innovations and the corresponding investment and other resources, on the one hand, and on the other hand, is implemented in conditions of high uncertainty and risks. The research uses the following methods: comparative analysis, a systematic approach based on which General and specific features of project management are identified, as well as abstract-logical. In the context of globalization, modern management principles require a team approach to solve problems aimed at achieving the strategic goals of companies, organizations and States, as well as ensuring continuous improvement of business processes, implementing any changes of a socio-economic, organizational or other nature. The processes that ensure an effective transition to project technologies, as well as important components of the project approach from the point of view of achieving project goals are identified. It is shown that project management is especially widely used in private companies. Currently, this tool is being actively implemented in the management system of state structures in different countries. The significance of the research results lies in the fact that knowledge about the project approach is generally recognized scientific direction, which is characterized as an independent sphere of professional activity and a system of lean management aimed at improving the economic efficiency of implemented projects. In General, despite the noticeable activation of project management promotion processes in Kazakhstan, it should be noted that an important task is to transfer modern technologies of the project approach as a tool for innovative development to all spheres of life of the Kazakh society.

Analysis of the state and problems of metallurgical cluster development of the Pavlodar region’s economy
Annotation:

The article analyzes the state and problems of cluster development in the real sector of the region based on the materials of the Pavlodar region. The main problem of innovative development of the Pavlodar region, as well as in all regions of Kazakhstan, in general, is the lack of innovative activity of enterprises, which is reflected in the volume, frequency and efficiency of their innovations. At the same time, most of the enterprises belonging to the real sector of the economy have sufficient resources for the development of innovative activity. However, the prospects for their interaction with enterprises in other sectors and sectors of the economy for the purpose of technology transfer are insignificant, which, in general, doesn’t meet the principles of balanced spatial development of the territory formulated by the program for the development of territories of the Republic of Kazakhstan until 2020. One of the ways to solve this problem is formation and development of a cluster approach and interaction of business entities. The article assesses the efficiency of the cluster’s functioning as an institution of regional development. On the example of the metallurgical cluster of Pavlodar region, the main ways and methods of forming cluster initiatives in the regional economy are considered, a SWOT analysis of the development of the metallurgical cluster of the region is given, and its main problems are identified; identifies priority directions of clusters’ development (metallurgical cluster, including the production of final products, the cluster of railway engineering, agri-food cluster), the realization of which in the region could create the conditions for the emergence and full development of a number of new highly specialized sectors such as cluster chemistry, cluster of road and construction machinery, transport logistics cluster, cluster of modern production technologies and engineering, cluster of manufacturing components for machinery and equipment and cluster of industrial electrical engineering and equipment for power engineering. The authors also noted that the realization of regional development strategies of cluster initiatives can potentially lay the foundations for clusters “future days”, such as: cluster of resource efficiency and environmentally processing, the cluster of new energy, the cluster of innovative medicine, tourism and recreational cluster.

Morphofunctional characteristic of endocrine part of pancreas under affecting of γ-HCH
Annotation:

In the last decades of the twentieth century, in the national economy of many countries, organochlorine pesticides were most widely used, characterized by stability in the external environment, the ability to cumulate in various tissues of organisms. Lindane (the gamma isomer of hexachlorocyclohexane) is listed as a restricted persistent organic pollutant and is an ecotoxic substance with severe and chronic effects on the human body. The study of the effect of lindane on carbohydrate metabolism at the present stage is still insufficient. This fact led to the study of the effect of γ-HCH on the insulinogenic function of the pancreas in in vivo and in vitro experiments. In experiments in vivo, the animals of the experimental groups were once orally administered γ-HCH at a dose equal to 1/5 DL50. Isolated pancreatic islets, precipitated in vitro and fixed on mica plates, were exposed to γ-HCH in amounts equivalent to 1/5 to 1/4 DL50. Paraffin sections of pancreatic tissue from experimental and control animals were stained with aldehyde fuchsin according to Gomori, and tissue preparations were also examined by a highly specific method for detecting insulin in β-cells using diethylpseudoisocyanin staining, followed by examination of the preparations in the ultraviolet light of a luminescent microscope.The same methods were used to study preparations of isolated pancreatic islet tissue on the 4th day of cultivation. The influence of orally administered γ-HCH on the level of immunoreactive insulin in the blood of experimental animals was also studied. The insulin level was determined by the enzymatic-immunological method. The concentration of IRI was established before the start of the experiment and 4-4.5 hours after acute inoculation. Results and their significance. In the study of stained preparations of the pancreas of experimental animals, numerous islets of ordinary sizes were revealed, the cytoplasm of which was filled with aldehyde-fuccin granularity in quantities indistinguishable from those observed by microscopy of preparations of control animals. The value of the fluorescence coefficient in the histofluorimetric study of the control and experimental preparations did not differ significantly. However, the content of IRI in the blood serum showed a distinct decrease in the first hours after priming. In experiments in vitro, when studying the effect of γ-HCH on cultured tissue, introduced into the nutrient medium on the second day, in the field of view of the microscope, single, small pancreatic islets were revealed. Their number on a constant area of the plates was significantly lower than the value of the same indicator in the study of control preparations. Thus it has been shown that γ-HCH does not affect the histostructure of the endocrine pancreas, but causes a significant decrease in IRI in the blood serum, as well as a change in the histochemical characteristics of cultured β-cells.

Development and research of means and methods for improving the efficiency of heat stations in the Republic of Kazakhstan
Annotation:

The main problem: This article is devoted to the key problems of the fuel and energy complex of the Republic of Kazakhstan: 1) lack of production capacity to meet the growing demand for energy and fuel from the economy and the population. Increased demand for electricity and heat, which will require the commissioning of new generating capacities.There is already a shortage in the fuel markets. Modernization and bringing the existing oil refineries (hereinafter referred to as refineries) to full capacity will not allow providing the domestic market until 2030; 2) the export orientation of raw materials, the dependence of the economy on the export of energy resources. In order to attract technology and investment in the oil and gas and nuclear industries, agreements on the extraction of energy resources were concluded with international export companies. In the medium term, Kazakhstan may face a shortage of oil for domestic refineries, if measures are not taken to stimulate its refining within the country. The uranium mined is fully exported; 3) high energy intensity of the economy, low level of energy efficiency. There is a high potential for increasing the efficiency of energy use both in the electric power industry and fuel production, and at the level of final consumption – in industry and housing and communal services; 4) decrease in the replenishment and quality of the resource base in the oil and gas, coal and nuclear industries; 5) low environmental friendliness of technologies used in the fuel and energy complex. Purpose: The purpose of the article is to reveal the problem in the field of ensuring the fulfillment of international obligations between different countries and their own energy sufficiency by gradually changing the structure of energy production. Methods: Studying the experience of increasing the efficiency of the use of energy resources and energy saving as a priority of the state policy of the country. Analysis of production capacity with a constantly forecasted shortage of primary energy resources and insufficient growth of capacity for the production of electricity and heat. Consideration of the possibility of compensating for the shortage by saving energy resources, increasing tariffs for energy carriers, as a stimulating factor for their effective use. Results and their significance: The results of this article will reflect the problems of energy, as the most important driving force of global economic progress. The well-being of the people depends on the state of the country's energy sector, therefore there is an urgent need to solve the emerging problems. The global energy problem is, first of all, the issue of stable and efficient supply of fuel and energy to mankind. Today, the energy sector of Kazakhstan is focused on fuel resources, since the country is provided with hydrocarbons and other energy resources. About 72 % of electricity in Kazakhstan is generated from coal, 12,3 % from hydro resources, 10,6 % from gas and 4,9 % from oil. Thus, the four main types of power plants generate 99,8 % of electricity, while alternative sources account for less than 0,2 %.

Ingularly perturbed equations in critical cases
Annotation:

Singularly perturbed partial differential equations with small parameters with higher derivatives deserve special attention, which often arise in a variety of applied problems and are used in describing mathematical models of diffusion processes, absorption taking into account small diffusion, filtration of liquids in porous media, chemical kinetics, chromatography, heat and mass transfer, hydrodynamics and many other fields. It is necessary to consider the creation of an asymptotic classification of solutions of singularly perturbed equations using a well-known approach to solving the boundary value problem. In this case, the singular problem is understood as the problem of constructing the asymptotics of the solution of the Cauchy problem for a system of ordinary differential equations with a small parameter with a large derivative. The asymptotics of the solution in all cases is based on the last time interval or the construction of a boundary value problem for a system with a weak clot in an asymptotically large time interval. Purpose - to construct and substantiate the asymptotics of solving a singular initial problem for a system of two nonlinear ordinary differential equations with a small parameter; To date, a number of methods have been developed for constructing asymptotic expansions of solutions to various problems. This is the method of boundary functions developed in the works of A.B. Vasilyeva, M.I. Vishik, L.A. Lusternik, V.F. Butuzov; the regularization method of S. A. Lomov, methods of averaging, VKB, splicing of asymptotic decompositions of A.M. Ilyin and others. All the above methods allow us to obtain asymptotic expansions of solutions for wide classes of equations. At the same time, such singularly perturbed problems often arise, to which ready-made methods are not applicable or do not allow to obtain an effective result. Therefore, the development of methods for solving equations remains a very urgent problem. As a result of the study, an algorithm for constructing an asymptotic classification of the initial solution of the problem with a singular perturbation is given, and approaches to estimating the residual term are also shown.

The task of creating a unified mechanism for state cadastral registration of land plots according to uniform rules and technologies for all, identification and individualization of land plots and objects of immovable property firmly associated with them, for subsequent state registration of rights to land plots and transfer of information to the territorial bodies of the State Revenue Committee, remains relevant. To study the experience of developed countries in the provision of public services in the system of land relations through the development of official land information systems. The article used general scientific methods from general to concrete one, synthesis, theoretical generalization, induction, deduction, and system analysis. Based on the studied experience of developed countries, relevant conclusions and proposals were made: information technology is a useful tool and can help overcome bureaucracy, backwardness, isolation, monopolistic practices, and inefficiency in the public and private sectors; the use of state bodies for effective regulation of geographic information (GIS) systems that allow solving a wide range of tasks, as well as the use of modern information technologies, contributes to the transition of the activities of state bodies to a qualitatively new level of state control, which allows for full transparency of information about the land fund and objects real estate of the country, as well as its availability to the population. The provision of public services in the field of land relations using information and communication technologies reduces entry barriers and transaction costs in business, increases competition, and improves mechanisms in this area.

Simulation of the working cycle of a diesel engine with a system of periodic shutdown of the cylinders
Annotation:

Combustion engines operate over a wide range of power and speed. To the greatest extent, this applies to automotive and tractor engines and diesel engines operating at fractional and idle loads for a significant part of the operating time. When designing engines, the choice of their main design and layout parameters is carried out in a comprehensive manner, taking into account the provision of the required power and efficiency in the modes of maximum torque and rated power. However, ensuring the economical operation of modern highly accelerated diesel engines at low loads and idling causes a whole range of problems related mainly to the organization of effective mixture formation and fuel burnout, as well as to ensuring stable fuel supply. Thus, the cycle dose of injected fuel in idle mode is 8–12 times less than the cycle dose in nominal mode, which determines increased requirements for fuel equipment and difficulties in ensuring high-quality mixture formation. At the same time, diesel engines operate in idle mode up to 50 % of the total operating time, consuming up to 15–20% of the fuel. For truck engines, the relative idle time is approximately 20–25 %. Thus, the development of measures to improve the efficiency of diesel engines at idle is relevant. The purpose is to perform a numerical analysis of the effect of switching off cycles in diesel engines for autotractor and diesel locomotive purposes on the working processes in the cylinder and the indicator parameters of the cycle in idle modes. When writing the article, traditional methods (comparison, description, and measurement), generallogical methods and research techniques (analysis, generalization, etc.) were used. A numerical analysis of the operating cycle of a diesel engine equipped with a cycle shutdown system was performed. The relationship between changes in fuel injection characteristics when cycles are turned off with indicator indicators of the engine operating cycle in idle load modes is disclosed. It has been established that the expediency of switching off cycles in a specific engine operation mode is determined primarily by the features of the injection, carburetion and fuel burnout processes.

Problematic issues on the formation and use of the budget of the Pavlodar region and ways to solve them
Annotation:

The sustainable socio-economic development of the regions is determined by a number of factors, including the implementation of an effective budget policy, which plays a special role for the performance of social functions, regulating Inter-level organizational relations, strengthening the economic and financial independence of the regions.Effective management of budget policy makes it possible to purposefully use the mechanisms of budget regulation at all levels of management. At the same time, it involves the implementation of a number of functions, of which the control function is the most important. In the system of economic relations, it is assigned to a specialized financial body – the Treasury. Topical tasks are: regulation of budget flows in the region, strengthening control over the receipt and targeted use of budget funds; improving inter-budgetary relations; increase the revenue base of budgets by increasing their collection; etc. In the process of solving these tasks, a number of managerial, organizational and methodological problems arise, the solution of which contributes to improving the effectiveness of the budget policy of the region and, as a result, its economic development. Objective - to study the regional specifics of the implementation of budget policy in terms of the formation and execution of local budgets on the example of the Pavlodar budget, identify the existing problems in the region and determine the directions for improving the budget process. The methodological basis of the study is formed by general scientific and special methods of cognition: analysis and synthesis, deduction and induction, historical, logical, structural-functional and comparative analysis, as well as individual scientific methods: statistical-economic and computational-analytical. The formation of the local budget is carried out through the application of a single methodology, a single budget legislation and orientation to the Strategic Development Plan of the Republic of Kazakhstan until 2025, developed for the implementation of the main document of the state planning system for the medium – term period-the long-term development strategy of Kazakhstan until 2050. The implementation of all the tasks set out in the strategic development plans of the Republic will begin at the level of local budgets. The solution of State tasks is guaranteed, first of all, to meet the needs of the population at the local level. The role of regions in the entire process of reproduction cannot be overestimated, so the independence, flexibility and high degree of efficiency of using budget funds at the local level is the key to the successful development of society, production and business in any territory.

The possibility of using correlation and regression analysis in ecological and economic research at oil refineries
Annotation:

It is known that an increase in the volume of production in any sphere of production as a consequence increases the intensity of anthropogenic impact on the environment, including the atmosphere. This problem is especially typical for oil refineries. On the one hand, this is due to the complexity of oil refining processes and the release of various hydrocarbon compounds into the atmosphere during processing. Therefore, when implementing sustainable ecological and economic development in the Azerbaijani regions that are associated with oil refining, an increase in the volume of products should not create an increase in environmental impact. This problem is considered one of the factors directly affecting the economic situation of the enterprise, as well as creating certain environmental, social and economic problems for society as a whole. The purpose is to study the possibility of using the correlation-regression method in solving the problem of determining the presence of the decapling effect. The relationship between the volume of petroleum products produced and the amount of pollutants released into the atmosphere is random and is characterized by stochastic and statistical dependence. At the same time, on the basis of a mutual comparison of the methods of correlation and regression analysis and the method of production function, the effectiveness of correlation and regression analysis is determined. The methodological basis of the work was the scientific works of scientists-economists, mathematicians providing the definition of the decoupling effect at industrial enterprises. In the presented methodology, the obtained estimates of the performed in real time vary depending on the values of the set parameter. When developing the presented methodology, the STATISTIKA software package was used. This program was developed by StatSoft. Based on the obtained and experimentally verified data, the equation of linear regression dependence is determined. During the research, it was found that in some cases it is not possible to evaluate the statistical characteristics of a random variable or it is accompanied by serious errors. Therefore, when processing data, instead of mathematical expectations and variances, we used selective mathematical expectations and variances. The analysis of the ecological and economic situation of oil refineries based on correlation and regression analysis allows us to determine the presence of the decapling effect. The obtained correlation coefficient between the volume of production oil products and the volume of emissions into the atmosphere shows that there is no statistically significant relationship between these parameters. Thus, there is an achievement of the decoupling effect between the production of petroleum products and the volume of emissions of pollutants into the atmosphere.

The use of a heat pump at an industrial enterprise in the region
Annotation:

Main problem: The use of waste heat is most often solved by installing heat exchangers, but this is not effective when the temperature of this heat does not exceed 10-15 0 C, in which case this heat can be used using a heat pump. Where can I get this heat? Almost any enterprise needs cooling of any equipment elements or substances – working fluids; the heat received from them can be sent to a heat pump and used here at the enterprise. Purpose: Consideration of the possibility of using the heat of cooling water from the pump CNS 60-165 and the proposal of a new scheme with the installation of a heat pump that uses this heat. Methods: This is achieved due to the fact that it is proposed not to discard the heat, but after its use in the heat pump evaporator, transfer it to the heated medium - water, which is then sent to the shower cabins of the enterprise. Since the showers are located in the same room, the cost of transporting heat and losses will be minimal. Methods: In the course of the research, the possibility of using the waste heat of an industrial enterprise for using it here at the enterprise for the purposes of hot water supply was considered. For these purposes, it is proposed to install a heat pump, thanks to which the thermal potential increases, which makes it possible to fully use the received heat. Results and their significance: As the experience of foreign countries has shown, heat pumps can be widely used in many industrial enterprises, and in conditions of increased competitiveness, in order to reduce energy costs and the cost of manufactured products, install heat pumps to utilize excess heat, for example, process water, which is available in many production allows you to have a significant economic effect.

Energy savings through the use of refractory masonry with a lower thermal conductivity
Annotation:

Main problem: recently, much attention has been paid to energy saving in production, especially when it comes to industrial units that burn fuel. There are several ways to maximize the use of the heat released during the combustion process, for example, to reduce the temperature of the flue gases at the outlet of the unit, by maximizing its use, both in the technological process itself and by installing additional heat-receiving units, for example, air heaters or other heaters. Another way to save money is to reduce heat losses through the lining of these high-temperature units. Metallurgical units that consume a large amount of energy and fuel require an analysis of their consumption, and ways to save their consumption based on the results of the analysis. Purpose: this article considers the possibility of replacing the existing inner insulation layer of the second and third sections of a high-temperature unit - a metallurgical furnace, with a new one with better technical and economic indicators. Methods: the possibility of replacing the existing inner insulation layer of the second and third sections of the high-temperature unit with a new one, with the best technical and economic indicators, was considered. The calculation of heat losses by thermal conductivity through the side surfaces and the roof with new insulation was performed, and the economic efficiency of the proposed solution was proved. Results and their significance: replacing the existing inner layer of insulation - refractory concrete PHLOCAST M30 (thermal conductivity coefficient from 1,4 to 1,45) with the proposed CERALIT GUN HK 70070 (thermal conductivity coefficient from 1,03 to 1,12) will reduce heat loss to the environment, and thus to reduce fuel consumption for the furnace.
