Abstract

PURPOSE:In desufurizing and dephosphorizing simultaneously molten pig iron by the addition of iron oxide and quick lime, it is intenced to reform molten pig iron into a material for ductile cast iron castings or alloy cast iron castings in a short time by performing the above-mentioned addition at two stages.
