IPC: C21C1/02
Filed: 2009-07-08
Abstract: PROBLEM TO BE SOLVED: To simply and stably perform desulfurization treatment to an extra-low sulfur concentration at high efficiency without using an LF apparatus and a vacuum-degassing apparatus with high facility cost and treating cost and without adversely affecting the environment.SOLUTION: The method for desulfurization refining molten iron in a refining vessel includes: (i) a first step in which the desulfurization treatment is applied by adding desulfurizing agent into the molten iron; and (ii) as a second step in which a plasma-arc having 1-100 vol.% oxygen concentration in a plasma gas-flow, is irradiated onto the desulfurizing slag from the upper part of the slag so as not to reach the molten iron under state of leaving a part or the whole of the desulfurizing slag generated so as to cover the whole surface of the molten iron in the first step, and S concentration in the molten iron after finishing the second step, is made lower than the S concentration in the molten iron after finishing the first step. After finishing the second step, the molten iron and the slag are deoxidized with the deoxidant (a third step). As the desulfurizing agent, a flux substantially containing no fluorine or the slag generated with the desulfurization refining method is used.
