摘　　要：介绍了钒铁冶炼过程中发生的化学反应、对钒铁炉渣物理性质的要求,分析了电硅热法冶炼钒铁炉渣碱度对钒收率、电量消耗、炉体寿命和渣包寿命的影响。通过试验,认为调整炉渣碱度在1.8~2.5,可以提高钒收率、炉体寿命、渣包寿命,降低电量消耗。It is introduced the chemical reaction in ferrovanadium smelting,the demand for the physical property of ferrovanadium slag,discussed the influence of slag basicity in ferrovanadium smelting with electro-silicothermic process on vanadium recovery rate,power consumption,furnace work life and slag ladle work life. It is considered from test that the slag basicity is adjusted to 1. 8 to 2. 5 can increase vanadium recovery rate,prolong the work life of furnace and slag ladle and reduce power consumption.
