Abstract
PURPOSE: To stirr the melt efficiently by a method wherein a lance provided with two gas injection holes formed perpendicularly to a gas passage is immersed into the molten iron or steel in the vessel and a gas is injected into the melt while rotating the lance in the melt.
CONSTITUTION: Molten pig iron or steel is placed in a heat-resistant vessel 2 and the melt 4 is stirred by injecting the gas through the lance 1 to refined the melt 4 through desulfurization, dehydrogenation, deoxidation and the like. The lance 1 used in this case is provided with two gas injection holes 1b formed perpendicularly to the gas passage 1a, and is rotated in the melt 4 at a rate of 1W20rpm. The gas injected is dispersed uniformly into the melt 4 in the horizontal direction and then migrates upwards to stirr the melt 4 and molten slag 5 efficiently, enhancing the refining effect.
