Dephosphorization of Steels – IspatGuru
Aug 15, 2016· The initial comprehensive studies on dephosphorization were conducted during the 1940s. These studies observed that FeO and CaO are necessary slag constituents for the dephosphorization of steel. These studies also showed that the dephosphorization reaction is exothermic and that the slag capacity for dephosphorization decreases with temperature.
