Raw Materials for Steelmakingng processes. The oxidizing agents used for steelmaking are air, oxygen and iron oxide. Lime is generally added during steelmaking to make the slag basic enough to retain phosphorus and sulphur in the slag phase. The pre-treatment of hot metal is carried out for improving cost-effectiveness in steel

S. E. Crowe,X. Fan,S. Behar,G. YeBlast furnace reactions play an important role in BF production. Heat and reducing gas are generated in tuyere zone. Reducing gas goes upwards, solid charge materials come down, and counter-current interaction reactions take place at the upper zones. Slag-metal reactions take place at the hearth.
