摘要： PURPOSE: To melt and manufacture a dead low steel sulfide at a low cost by removing a converter slag on a molten steel, and thereafter, adding a desulfurizing flux onto the molten steel, and arc-heating the molten steel.
CONSTITUTION: A molten steel is discharged to a ladle from a converter, the ladle is carried into a slag removing equipment, and a converter slag on the molten steel is removed. It is desirable that this slag removal is executed by a vacuum absorbing method. After the slag has been removed, a desulfurizing flux is thrown into the ladle, an electrode and a stirring gas leading-in lance are made to descend on the molten steel, a cover is put on the ladle, and the molten steel is put into an Ar gas atmosphere by leading in an inert gas of an Ar gas, etc. Also, an arc is formed at a prescribed arc gap between the electrode and the molten steel. As a result, the molten steel is heated, also the flux is slagged, and a slag layer which is optimum for desulfurization is formed on the molten steel. At the same time, when the molten steel is stirred weakly by leading in an Ar gas, the slag and the molten steel react effectively, and a dead low steel sulfide whose S density is ≤about 5ppm is obtained.
