Abstract

This study focuses on the viscosities of synthetic slags used in secondary refining operations. Typically, these slags contain mainly CaO, Al₂O₃, MgO and SiO₂. The data for LF slag viscosities are used in a model for a gas-stirred ladle to evaluate the effect of viscosity variations on predicted parameters close to the slag/steel interface. The results show that viscosities of LF slags significantly affect ladle refining operations. It is therefore necessary to control the composition of the synthetic slags carefully during production.
