摘　　要：采用热态改质的方法,在电炉渣排放源头对其进行改质试验,试验结果表明,原渣碱度降低后,改质渣的上磁率得到显著提高,促进了其铁质组分的回收;同时,磁选后尾渣中游离氧化钙的含量也降低,满足钢渣应用在水泥混凝土行业的国标要求。Technology of molten slag modification was utilized at the beginning of taping slag in elec- tric arc furnace. The results indicated that recovery of iron components was improved by magnetic separa- tion significantly with decrease of basicity of the slag. Meanwhile, free-CaO content of tailings after mag- netic separation reduced with the decrease, which was satisfied to national standards of application of steel slag in cement and concrete industry.
