| Abstract: | When smelting reduction and alloying of chromium and nickel concentrate with C-Si-Al as compound is conducted in a plasma induction furnace, the alloying target value of 18% Cr and 9% Ni could be achieved in 20 min, the recovery rate of Cr and Ni would reach 82%-85% and 95%-98%respectively. Content of C could be limited within 0.326%. The properties of electrochemical reaction between plasma and plasma smelting slag and also analysed. |
