CaO-SiO2-FeOx-P2O5-MgO bearing slags are typically used in the basic oxygen steelmaking (BOS) process. This study investigates the partition ratio of phosphorus between slag and steel as an index of the phosphorus holding capacity, which affects the attainable phosphorus content in finished steel. Conducted at varying concentrations of FeO and basicity levels, results indicate that the partition ratio initially increased with basicity but plateaued beyond thresholds of 2.5 to 2.6. Notably, increasing FeO content up to 18 to 20 mass pct enhanced phosphorus partitioning at a basicity of 2 to 3; however, higher FeO concentrations subsequently decreased the partition ratio, the transition point varying with basicity and temperature. At lower basicities, phosphorus partition showed little change or a marginal decrease with increasing FeO. These findings provide crucial insights into slag behaviors in steelmaking, highlighting critical limits that optimize phosphorus control in the production process.
