Mathematical Model for Planning Experiments to Obtain a Metalized Product

Environmental pollution in Kazakhstan has reached a critical level. Waste from metallurgical complex enterprises is in most cases stored and not only disposed of, but also not used in places suitable for industrial use. Every year, more and more land is occupied for waste storage, and small waste is carried by wind over long distances. An analysis of waste disposal data from «Qarmet» JSC shows that for every ton of finished tread, about 2 tons of waste are generated. More than 130 million tons of sludge, coal processing waste, ash, slag and other products of metallurgical processing of mineral raw materials and fuel have been accumulated in dumps and dumps. At the current rate of processing, about 5 million tons are added to them annually (more than 1 ton per ton of finished steel). Many wastes from metallurgical production are of high quality in terms of their chemical composition, but cannot be used as raw materials in traditional metallurgical processes due to unsuitable physical and mechanical properties. These negative properties, compared to the traditional production method, are favorable for the effective organization of the solid-phase process of the reaction of metal oxides with solid carbon, since the surface energy of dispersed residues is high [1]. Goal: to create a mathematical model for planning experiments on waste management.
