METHOD FOR DESULFURIZING MOLTEN IRON

摘要

A method for desulfurizing molten iron is provided to reduce the temperature lowering of the molten iron due to desulfurating agent injection by recycling slag generated after KR desulfurization. A method for desulfurizing molten iron comprises: a step for pouring the molten iron on a ladle; a step for removing furnace slag blast furnace slag being generated in a furnace and being flowed out with the molten iron by transferring the ladle to KR desulfurization location and tilting the ladle with a tilting device; a step for injecting the exclusive slag; a step for injecting the desulfurizing agent and desulfurizing the molten iron through mechanically mixing; and a step for excluding the generated slag.
