摘　　要：介绍了传统高镁铝比铬矿镁质炉衬不能完全适应低镁铝比易熔难还原南非铬矿生产高碳铬铁,但通过调整电炉参数、工艺可以继续采用镁质炉衬或碳质冷凝炉衬使用南非铬矿生产高碳铬铁并取得较好的经济和技术指标.电炉参数主要调整炉膛直径、炉膛深度、极心圆直径,工艺上提高二次电压、使用铬矿球团或烧结矿,通过电炉参数和工艺调整,使用南非矿生产高碳铬铁基本可以达到使用其他高镁铝比铬矿的冶炼效果.The traditional high magnesium aluminum ratio chromite magnesia lining can no longer fully adapt to the production of high carbon ferrochrome from South African chromite with low magnesium aluminum ratio,fusibleness and difficult reduction.However,by adjusting the parameters and processes of the electric fumace,magnesia lining or carbonaceous condensing lining can continue to be used to produce high carbon ferrochrome from South African chro-mite and achieve good economic and technical indicators.The parameters of the electric fumace are mainly adjusted for furmace diameter,fumace depth,and electrode circle diameter.In terms of process,the secondary voltage,chromium ore pellets,or sintering can be increased.By adjusting the parameters and process of the electric furnace,the produc-tion of high carbon ferrochrome using South African chromite can basically achieve the smelting effect of using other high magnesium aluminum ratio chromium ores.
