Dephosphorization of Steels – IspatGuru

In this case, dephosphorization depends substantially on the ratio of the steel to slag weight The role of these factors can be deduced from the following P balance equation (P content in ladle slag) + (P content in ladle steel) = (P content in tapped metal) + (P content in slag trapped by steel in ladle) + (P from deoxidizers)
