Abstract

Slag practice is one of the most important factors in molten steel production. Physical and chemical properties of slag determine the efficiency of the production process. Slag electrical conductivity is the second effective parameter in slag practice after viscosity. During current study, effect of temperature, FeO, CaO, SiO2 content and basicity ratio B2 on slag’s electrical conductivity was studied experimentally. It was found that, electrical conductivity increases with increasing temperature, %FeO, %CaO and basicity B2. On the other hand electrical conductivity was decreased with increasing SiO2 content. Specific conductance and electric conductivity index for slag main constituents were also estimated.
