Oxygen Steelmaking Processes medium phosphorus, is used for LD process, to remove phosphorus from the hot metal, lining of converter is always basic. In LD converter, reactions are basically slag-metal reactions. The mass transfers are occurring by force convection which is caused the turbulence of the bath.
