发明名称 METHOD FOR CONTROLLING ELUTION OF FLUORINE FROM STEEL SMELTING SLAG
摘要 PROBLEM TO BE SOLVED: To inexpensively provide a method for controlling elution of fluorine, which can effectively control an eluting amount of fluorine from steel smelting slag containing fluorine. SOLUTION: This control method is characterized by mixing the steel smelting slag containing fluorine with one or more materials for controlling elution of fluorine, selected among solidified hydrate of fine powders of blast- furnace slag, slag in a furnace for smelting/reducing chrome ore, secondary smelting slag discharged from a secondary smelting process without using the fluorine-containing material, and porous carbide.
