摘要: CaO-SiO2-FeO x -P2O5-MgO bearing slags are typically used in the basic oxygen steelmaking (BOS) process. The partition ratio of phosphorus between slag and steel is an index holding capacity slag, which determines content achievable finished steel. influence factors such as FeO basicity on was investigated at two different temperatures. initially increased with but remained constant beyond a 2.5 to 2.6. An increase up 18 20 mass pct beneficial for level 2 3, higher concentration resulted decrease ratio; corresponding this transition varied temperature. At even lower basicities, however, equilibrium showed either no change, or marginally decreasing trend, content.
