Abstract
PURPOSE: To enhance the efficiency of stirring the melt by a method wherein a lance having gas injection holes formed perpendicularly to the axial direction is immersed in the molten iron or steel in the vessel and a specified amount of gas is blown into the melt through the lance.
CONSTITUTION: Molten pig iron or steel is placed in a laddle 2, then a slag 5 for refining is formed and the melt 4 is heated as required by passing current through an electrode 3. Thereafter, the lance 1 is immersed into the melt 4 and an inert gas such as Ar gas is blown in from the tip end of the lance 1 to stirr the melt 4 and the molten slag 5, thereby refining the melt 4 through desulfurization and the like. The lance used in this case has one or two gas injection holes 1a formed perpendicularly to a gas passage provided along the axis of the lance. The gas is blown in at a rate of 4W20Nl/min per ton of the melt. Accordingly, the melt 4 and the molten slag are stirred efficiently and the refining effect is enhanced.
