Abstract

The solubilities of MgO obtained from the data obtained from equilibrium experiments between liquid CaO-SiO2-Al2O 3-FetO-MnO slags and liquid silver and solid iron in the temperature range of 1 703 to 1 773 K in a CO/CO2 gas mixture are analyzed in the current study. The solubilities of MgO decreased with increasing FetO content and the slag basicity, (mass% CaO)/(mass% SiO 2) in the slag basicity less than 2.0 and they were compared with the change of the MgO solubility with increasing MnO concentration in the slags. The present data were temperature-extrapolated to those at 1 873 K and compared with the previously reported MgO solubilities in steelmaking slags. The application of the optical basicity resulted in correlation of MgO solubility with COREX process-typed slag compositions.
