概要

The solubilities of MgO obtained from the data obtained from equilibrium experiments between liquid CaO–SiO2–Al2O3–FetO–MnO slags and liquid silver and solid iron in the temperature range of 1703 to 1773 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% SiO2) 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 1873 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.
