Phosphorus Partition and Phosphate Capacity of TiO₂ Bearing Basic Oxygen Steelmaking Slags

The phosphorus partition (LP) and phosphate capacity () were measured for TiO2 bearing basic oxygen steelmaking slags in the CaO–SiO2–MgO–FetO–(TiO2–MnO–Al2O3–P2O5) system at 1650°C. The effect of slag and metal additions were tested by varying the TiO2 content from 0.0 to 18.0 mass% and the [Ti] content from 0.009 to 0.301 mass%. A recently published LP model was used to assess the experimental LP data using the measured slag composition and temperature. Experimental LP data from this study and literature data were used to modify the published model to include titania.
