摘要：

The manganese distribution ratios between CaO-SiO2-FetO-P2O5 (less than or equal to 0.9 mass%)-MnO (8-16 mass%) slags and liquid iron were determined at 1873 K in a MgO crucible. The activity coefficient of MnO and the values for k(Mm) =(mass%MnO)/{[mass%Mn].(mass%T.Fe)} and C-Mn=(mass%MnO)/{a(Mn) . a(o)} were formulated as functions of slag composition and temperature. By using these formulas, the manganese distribution ratios at 1623 and 1923 K were estimated as functions of total Fe content and (mass%CaO)/(mass%SiO2) ratio. The manganese contents in hot metal and steel were also estimated as functions of manganese distribution ratio, slag volume and amount of manganese ore by using the mass balance relation.
