In the article presents the results of studies on the effect of temperature and pressure on the chloride sublimation of zinc and lead from converter dusts of steel production. Currently, an objective necessity is the development of dust utilization technologies for converter steel production, with its further use in production and production of by-products. The use of dust allows not only to save natural raw materials, but also increases production efficiency and improves the environmental situation. The content of non-ferrous metals in dusts makes it difficult to process and use them in agglomeration or in blast furnace production, while the iron content in converter dusts (sludges) makes it possible to use them as promising metallurgical raw materials. Therefore, for a more complete processing of dusts, extraction of non-ferrous metals from them is proposed. The purpose of this work was to determine the possibility of extracting zinc and lead from sludges of the converter production by the method of chloride sublimation. We used dust containing: 86,3 % Fe2O3, 3,5 % FeO, 0,9 % Al2O3, 1,6 % CaO, 0,9 % MgO, 1,1 % MnO, 0,8 % SiO2, 4,4 % ZnO, 0,5 % PbO. The study was conducted in the temperature range 200-1600 degrees C and pressures of 0,01; 0,1 and 1 bar based on a complete thermodynamic analysis using the HSC – 5.1 software package. Finnish metallurgical company Outokumpu, based on the principle of minimum Gibbs energy. According to the results of the studies, it was found that, at normal pressure, lead chloride sublimationbegins at a temperature of 600 degrees С, and zinc - at 900 degrees С: a decrease in pressure to 0,01 bar reduces the temperature to 500 degrees С and 700 degrees С, respectively; lead chloride sublimation under equal conditions is more complete than zinc; To achieve zinc chloride distillation at the level of 90-96 %, the process must be carried out at 1145-1200 degrees С and pressure from logP = -2 to 1,2 bar, while the degree of lead chloride distillation is 99,8-100 %.

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.

Main problem: The key task of the development of the regions of the Republic of Kazakhstan is to ensure their sustainable socio-economic development by increasing its competitiveness and innovation activity. To develop a successful strategy, as well as for its subsequent successful implementation, it is necessary to have a clear vision and idea of what the region will be like in the near future. This vision should be clearly formulated and understood by all interested parties in order to properly coordinate efforts in achieving the set goals. In turn, based on the vision, various initiatives and activities are being formed, the implementation of which is aimed at implementing the main directions of sustainable development of the region. Purpose: to consider the main directions of the implementation of the strategy of competitive, sustainable and safe development of the region. Methods: The theoretical and methodological basis was the concepts, hypotheses and theories presented in the works of domestic and foreign researchers. The methodology is based on a systematic approach, within which methods of comparative, factorial, subject-object; structural-functional, statistical analysis and extrapolation have been applied. Results and their significance: In order to ensure the sustainable development of the Pavlodar region in the future, there is a need to form the basis for the creation of new sectors, as well as to consider opportunities to diversify the regional economy. Currently, there is a structural change in jobs, which leads to an increased role of professional services industries in the field of information technology, engineering. It should be noted that the level of development of small, medium-sized businesses and entrepreneurship in the region is at a low level, due to the predominance of resource sectors in the economy. These sectors, due to the peculiarities of the technological process, do not form a system of suppliers around themselves. However, in order to ensure the progressive development of the industrial complex in the region, it is important to create conditions for the development of SMEs in the region and, accordingly, a system of suppliers around leading manufacturing enterprises. The high competitiveness of the Pavlodar region in the future until 2030 will be ensured through the development of priority clusters, as well as through the emergence of new industrial sectors of the economy. Thus, the priority clusters of «today» include: metallurgical cluster, including the production of end products; cluster of railway engineering; agro-food cluster.

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.
