Project idea. Development of mathematical models that can be used to optimize the composition of coal charges, control the expansion pressure index during recharging, and reduce the number of experimental measurements in specific coke production conditions. The goal is to assess the possibility of predicting the expansion pressure of coal charges, taking into account their technological properties and petrographic characteristics, as well as to study the effect of expansion pressure on the metallurgical properties of coke. Working hypothesis. When forming the composition of coal charges for coking, it is necessary not only to solve the problem of obtaining metallurgical coke with high physical and mechanical characteristics, but also to ensure optimal operating conditions and preservation of the furnace fund, taking into account the expansion pressure of coal raw materials. Expansion pressure should be understood as the pressure exerted by coal mass that has become plastic, provided that it is unable to expand freely. The main cause of expansion pressure is considered to be the pressure in the plastic layer of steam-gas products of thermal decomposition of coal, which is transmitted through semi-coke-coke to the refractory wall of the heating chamber of the coking chamber, causing it to bend.
