摘　　要：Two processes of making stainless steel in electric furnace- AOD furnace and converter furnace- AOD furnace by using chromite are suggested.The analysing and computing results show that the energy consumption and cost of the processes suggested are lower than those of the traditional process by using ferrochrome.The crude stainless steel liquid with chromium content of 15% is obtained in hot mode experiment of chromite reduction.The kinetics of chromite reduction is discussed according to the experiment results.The relations of pre-reduction rate and smelting reduction rate of chromite with the factors that affect the reduction rate are derived.Two processes of making stainless steel in electric furnace- AOD furnace and converter furnace- AOD furnace by using chromite are suggested.The analysing and computing results show that the energy consumption and cost of the processes suggested are lower than those of the traditional process by using ferrochrome.The crude stainless steel liquid with chromium content of 15% is obtained in hot mode experiment of chromite reduction.The kinetics of chromite reduction is discussed according to the experiment results.The relations of pre-reduction rate and smelting reduction rate of chromite with the factors that affect the reduction rate are derived.
