Abstract

Flexibility in raw material has prompted interest in better control of phosphorus (P) in molten steel. While significant work has been done on the partition of phosphorus to slags with chemistries relevant to those in the Basic Oxygen Furnace (BOF), there is little reported work on slag chemistries corresponding to that in Electric Arc Furnace (EAF) when direct reduced iron (DRI) is used. In the current phosphorus equilibration between molten Fe-P alloys and slags relevant to EAF-DRI manufacturing is carried out and the thermodynamic limit is compared to existing partition correlations developed for BOF. It is found that the existing correlations cannot be extended to EAF-DRI conditions and a new correlation is presented. The correlation based on thermodynamic data measured in the laboratory is validated with EAF plant data.
