<p><P>PROBLEM TO BE SOLVED: To provide a method for recycling desulfurization slag where, when CaO-based desulfurization slag generated in desulfurization treatment for hot metal is recycled as a desulfurization agent for hot metal, the desulfurization capacity of the desulfurization slag is secured, and the desulfurization treatment can be stably performed. <P>SOLUTION: When CaO-based desulfurization slag generated in desulfurization treatment for hot metal is recycled in desulfurization treatment for another hot metal as a part of a desulfurization agent, desulfurization slag in which CaO/SiO<SB>2</SB>in the slag composition is≥2.5 by mass ratio, the content of Al<SB>2</SB>O<SB>3</SB>is≤10 mass%, and the content of sulfur is≤5.0 mass% is recycled as a desulfurization agent. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
