摘　　要：不锈钢除尘灰是一种回收利用价值很高的工业危废,通过加入黏合剂使除尘灰和其他回收返矿混合后进行冷压球,再送至炼钢、矿热炉予以使用,这可以实现金属回收再利用,同时还可以解决工业危废难处置的问题。此外,分析将除尘灰用于烧结混料这一长流程处置工艺中所产生的经济效益,并与将其压球后用于炼钢或矿热炉这样的短流程工序所产生的经济效益进行对比,以助相关企业能够选择最优的除尘灰的处置方式。Dust removal in stainless steel steelmaking process is a kind of hazardous industrial waste with high recycling value.By adding adhesives and other recycling and returning ores to mix for cold pressing ball,and then sending it to rotary kiln and steelmaking for use,metal recycling can be realized and the problem of difficult disposal of hazardous industrial waste can also be solved.In this paper,the long process of dust removal used for sintering mixing is compared with the short process after pelleting used for steelmaking or mineral heating furnace,so as to make a better choice for the company in the way of dust removal disposal.
