Abstract

Based on the equilibrium model with two isothermal reactors, the influence of CaO and MgO oxides on the ferrosilicon process in the submerged arc furnace was determined. The influence of addition of CaO and MgO oxides in the feed mixture on the SiC carbide phase formation, the contents of Ca and Mg elements in the chemical composition of the FeSi alloy as well as the efficiency of the carbothermal reduction process have been determined.

Keywords: Ferrosilicon process, equilibrium model, Gibbs Minimization Method, submerged arc furnace
