英国Dary Mckee研究与开发中心应用等离子技术处理电弧炉冶炼不锈钢(含ZnO10—15%)和碳素钢(ZnO15—20%)时产生的含锌烟尘,已获得成功。被处理的含锌烟尘的组成如下(%,分子为炼不锈钢烟尘,分母为炼碳素钢烟尘):Fe_2O_330—60/30—50;Cr)2O_310—20/1;NiO2—6/1;MnO5—10/<5;MoO_30.5—2.5/<0.5;ZnOl—10/15—25;PbO0.2—2/1—5。烟尘中金属氧化物含量为50—60%,其余为渣成分:SiO_2、
The Dary Mckee Research and Development Center in the United Kingdom has achieved success using plasma technology to treat zinc-bearing soot produced by electric arc furnace smelting of stainless steel (containing ZnO 10-15%) and carbon steel (ZnO 15-20%). The composition of the zinc-containing soot to be treated is as follows (%, smelt stainless steel soot for molecular and denominator for smelting carbon steel soot): Fe_2O_330-60 / 30-50; Cr) 2O_310-20 / 1; NiO2-6 / 1; -10 / <5; MoO_30.5-2.5 / <0.5; ZnOl-10 / 15-25; PbO0.2-2 / 1-5. Soot in the metal oxide content of 50-60%, the rest of the slag components: SiO_2,
