摘　　要：介绍了锰硅合金冶炼中配加兰炭后,冶炼指标、炉渣和电气控制的变化。通过配入部分兰炭作还原剂,炉料电阻增大,有利于电极深插;配入兰炭炉料的电阻发生变化,入炉固定碳量及炉况会发生变化,经过摸索寻找最佳电气制度和配碳量。兰炭的价格低于冶金焦可以降低锰硅合金生产成本。The changes of smelting index,slag and electrical control after adding semi-coke in ferromanganese-silicon smelting are introduced.By adding some semi-coke as reductant,the charge resistance increases,which is conducive to the deep insertion of electrode.The resistance of adding semi-coke charge changes,and the fixed carbon content and furnace condition will change.It’s necessary to explore and find the best electrical system and carbon addition test.The price of semi-coke is lower than that of metallurgical coke,which can reduce the production cost of ferromanga-nese-silicon.
