摘要： PROBLEM TO BE SOLVED: To provide a slag-making agent for iron and steel, and manufacturing method therefor by which a slag-making property can be improved and desulfurizing reaction can efficiently be performed. SOLUTION: The slag-making agent for iron and steel exists under combining state of calcium fluoride on the surface of granular material composed of lime or light-burnt dolomite and the existing amount of the calcium fluoride is 8-35 mass% to the total amount of the calcium fluoride and the lime or the light-burnt dolomite. As the granular material, the one composed of the lime is desired. Further, it is desirable that the granular material has 2-30 mm grain diameter. Such slag-making agent for iron and steel, is manufactured by contacting the granular material composed of the lime or the light-burnt dolomite with an organic fluorine compound under heating state at 600-1,100°C and decomposing the organic fluorine compound and reacting the fluorine generated by decomposing with the lime or the light-burnt dolomite. As the organic fluorine compound, a hydrofluorocarbon is desirable. COPYRIGHT: (C)2009,JPO&INPIT
