| Abstract Scope |
The phosphorus content of the hot metal is higher than the range and optimal content of hot metal normally used for steel making in LD converters at EISCO. Therefore adequate care is necessary to investigate slag/metal partition of phosphorus.
The activity of total ferrous oxide in the slag was estimated according to the model of regular ionic solutions, it was used to find the concentration of oxygen in the metal. The activity coefficient of phosphorus and oxygen in the metal are 1.1195 and 0.8367 respectively.
By using the phosphate capacity, phosphorus distribution between slag and metal could be calculated; the effect of temperature on both phosphate capacity and phosphorus distribution ratio is large, while the influence of slag composition is small. |
