<p><P>PROBLEM TO BE SOLVED: To provide a slag recycling method by which degradation of the yield of steel is prevented, time loss in discharging slag is reduced, and slag discharge and the amount of desulfurizing agent to be used is reduced. <P>SOLUTION: High-temperature desulfurization slag produced in desulfurization of molten iron or high-temperature desiliconization/desulfurization slag produced in desiliconization/desulfurization of the molten iron is not discharged from a reaction container 1, but recycled in a high-temperature state, and used for desulfurization of molten iron of a next charge. Thus, recycling of the arbitrary number of times can be realized, the slag discharge can be markedly reduced, and the desulfurization rate can be improved. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
