摘　　要：采用直流等离子体枪系统，进行熔化还原反应，实验研究从电弧炉的烟尘中回收金属的可能性，各种气体对还原ＮｉＯ、Ｃｒ＿２Ｏ＿３和Ｆｅ＿３Ｏ＿４的能力，以及为使渣的浸出液符合法定排放标准的造渣剂添加条件。Metal recycling of electric arc furnaces dust was investigated through smelting reduction process using DC plasma burner system. The ability of various gases to reduce NiO,Cr_2O_3 and Fe_3O_4 was tested.Selective addition of slag-forming agents permitted the leacking liquor of slag to be lower than the legal limit.
