The Dynamic Interfacial Oxygen Potential Between Iron-Carbon Droplets and Oxidizing Slag

The dynamic nature of the interfacial oxygen potential during dephosphorization was investigated based on the concept that PO2$$ P_{{{\text{O}}_{2} }} $$ at the interface between slag and liquid metal is determined by the balance between oxygen supply from reducible oxides in the slag and oxygen consumption by alloying elements in the metal. Combining this approach with the knowledge that at the phosphorus reversion point the interfacial oxygen …
