Viscosity Measurements of CrO-bearing CaO–SiO₂–2%MgO–CrO Slag

Abstract

The influence of slag basicity and CrO content on the viscosity of CaO–SiO₂–2%MgO–CrO slags has been experimentally determined. The slag viscosity decreases with increasing basicity, CrO and Cr₂O₃ content. Both MgO and CrO have a basic characteristic and the CrO acts as a network modifier. The activation energy of the CrO content further validates these observations. The degree of polymerization is also found to decrease with the addition of CrO.
