用C－Si－Al复合还原剂在等高子感应炉内进行Cr－Ni精矿的熔融还原及合金化，钢中Cr和Ni的合金化目标值在20min内可达到18％和9％，Cr和Ni的收得率分别为82％－85％和95％－98％，碳含量可达到0．326％．还分析了等离子体和等离子熔体之间的电化学反应特性 The reduction and alloying of Cr-Ni concentrate in an isocentric sub-induction furnace with C-Si-Al composite reductant resulted in the target alloying of Cr and Ni in steel reaching 18% and 9% within 20 min, The recoveries of Cr and Ni are 82% -85% and 95% -98% respectively, and the carbon content can reach 0.326%. The electrochemical reaction characteristics between the plasma and the plasma melt are also analyzed
