Dephosphorization and desulfurization of molten pig iron by CaO-based fluxes were investigated at 1 370°C. The results indicated that simultaneous dephosphorization and desulfurization of pig iron were possible by a selection of flux composition for CaO-based system. By injection of fluxes containing iron oxide, oxidation state at flux-iron interface seemed to be locally controlled. This fact strongly suggested that simultaneous dephosphorization and desulfurization process could be achieved by a selection of flux composition and that of method on flux-metal contact for CaO-based fluxes.
