This article establishes the relationship between the various processes that take place in the furnace. Specifically: - heating of the charge due to its electrical resistance; - introduction of additional heat due to coke burning; - heat transfer processes in the volume of the furnace bath; - formation of melt and slag due to chemical reactions. The complete algorithm of operation of the ore-thermal furnace is presented. By means of which it becomes possible to model in dynamics the technological process of obtaining ferroalloys. Literature sources are presented, where a more detailed mathematical description of modeling the ferroalloy smelting process is presented. The model is reconfigured when changing the parameters of the charge, depending on its component composition and temperature value. Such as: - electrical resistivity; - mass heat capacity; - specific density; - thermal conductivity. The described algorithmic model is universal for obtaining different brands of ferroalloys.
