This paper deals with the combined process of production of ferrosilicon and power in an arc resistance furnace. Selected results of mathematical modeling of key installation units are presented. To this end, mathematical modeling, balance measuring methods and practical experience were used. From among the many activities required to implement the project, the author chose ones associated with: the furnace hearth, after-combustion area, flue gases and recuperator channel as well as the recovery system and flow characteristics of the device. The presented modeling study forms part of a new design method termed the integration of computational processes.
