摘　　要：为循环利用不锈钢炼钢过程中带出的除尘灰,解决不锈钢固体废弃物排放带来的环保问题,提出了短流程回收利用铁素体不锈钢除尘灰进行不锈钢电炉发泡造渣冶炼的方法。研制了以铁素体不锈钢除尘灰为主原料的不锈钢电炉发泡剂,开发了不锈钢电炉发泡造渣工艺。在100t电炉的实际使用中,每炉可回收利用5t以上的铁素体不锈钢除尘灰,发泡效果良好,基本上可全量回收不锈钢电炉发泡剂中带入的金属铁,并减少电炉冶炼铬损3.85%。Regarding the enviroment problem during stainless steel production, a new mode for stainless steel EAF slagging used recycled ferritic stainless steel dust was issued. The slagging agent were produced by the recycled ferritic stainless steel dust, and the EAF slaging process was developped. Application at the site, more than 5 t per furnace stainless steel dust are reclaimed,most metal iron in EAF slag are reclaimed and 3.85 % chromium losses are reduced in recycled ferritic stainless steel dust.
