Phosphorus Equilibrium Between Liquid Iron and CaO-SiO₂-MgO-Al₂O₃-FeO-P₂O₅ Slags: EAF Slags, the Effect of Alumina and New Correlation

Metals, 2019
The increased use of electric arc furnace (EAF) steelmaking using up to 100% direct reduced iron (DRI) has prompted an interest in better control of phosphorus since iron ore and, consequently, DRI have higher phosphorus and silica compared to scrap ...
