A process for dephosphorization-denitrification of Cr-containing pig iron by oxidizing refining is disclosed. Said process comprises maintaining the Si content of the molten iron at not more than 0.2%, contacting it with a slag comprising at least one of fluorides and chlorides of alkaline earth metals, at least one of lithium oxide and carbonate, and at least one of oxides of iron and nickel, while controlling oxidation of Cr. |
