摘要: AbstractA thermodynamic model applicable to the oxygen refining of ferromanganese was derived predict equilibrium concentrations for carbon, manganese and silicon. The based on activity determinations carbon manganese, spanning complete composition range Fe-Mn-C system. It built three data sources: dilute solution, saturation experimental at unity oxide in contact with alloy. temperature from 1350 1700°C, but agreement industrial scale suggests a validity about 1875°C. study predicts between 1 1.4% refined 1750°C. Silicon are below 0.22%. Optimal conditions high-carbon were suggested.
