ABSTRACT:
Molten pig iron is desulfurized, dephosphorized or otherwise refined by continuously admitting the molten pig iron into a stirring tank having an oval horizontal cross-section, causing the molten pig iron to flow in the longitudinal direction of the tank. An additive is incorporated into the stirring tank. Portions of the pig iron near the interface between the same and the additive are stirred by means of a plurality of vertical stirring rods or vanes which are suspended above the tank and project into the molten pig iron. Adjacent stirring rods or vanes are rotated in opposite directions such that their loci of rotations overlap with each other.
