Methods of energy saving increase under during agglomerate production at Aksu Ferroalloy Plant Branch of “Kazchrome” JSC

In this article issues of efficient use of ferroalloys production waste to save costs are considered; energy
efficiency of agglomerate production is calculated; sintering heat balance data are presented by a case study of
Aksu Ferrolloy Plant. According to the annual economic benefits calculation the folowing results are obtained:
due to аglogases recirculation, fuel saving is 1334.5 t.o.e.; due to reheating it is 1491 t.o.e.; due to installation
of thyristor converters to the unit the annual energy saving is 1714000 kWh.
Thus, it is identified that besides energy-efficiency measures during recycling of solid and gaseous
wastes, the use of agglomerate increases IPF electric furnaces performance as well, decreases specific energy
and reducing agent consumption which means the prime cost of finished products will be reduced.
