摘　　要：目前钢渣的处理主要采用热闷、热泼法处理,热泼法处理后仍有大量尾渣无法有效利用。钢渣含有约10%的金属铁和20%以上的氧化铁、硅酸钙无机材料,且富含高热值。在熔融条件下对钢渣进行铁沉积和氧化铁还原处理回收铁,改性后的尾渣用于制备高活性渣粉,可实现熔融钢渣的全部资源化利用。该技术处理钢渣具有产品附加值高,能耗低,市场空间巨大的优势,具有较好的发展前景。Currently, tank-type hot disintegrating method and heat spill method were the main treatment methods for the steel slag. But there was still tremendous amount of tailing slag without valuable use after treatments by heat spill method. There were about 10% iron metal, more than 20% iron oxide, calcium silicate inorganic materials in steel slag and its＇s rich in high calorific value. Under molten condtition, the iron was extracted from steel slag by iron deposit and reduction of iron oxide, tailing slag was used for making slag power having high activity index after its composition modificated, and thoroughly utilization of molten steel slag became true. This treatment technique of steel slag had high economic value, low energy consumption, and a large market prospect. This technique should be given further industrialization study and extended for application.
