摘　　要：以V2O5和V2O3混合物料为原料,铝钙铁为精炼剂,采用电铝热法制备了高钒铁,并对其相关工艺参数进行了研究。得到的较佳的工艺条件为:铝用量为理论量的103%(质量分数,下同),以铝钙铁为精炼剂,精炼剂加入量为100g,精炼时间30min,高钒铁的回收率可达98%;精炼剂铝钙铁加入量以100g为宜,加入过多易使钒铁中铝含量偏高,影响合金的质量。High vanadium ferrovanadium was smelted with mixture of Ve O2 and V2 03 as raw material, A1-Ca-Fe alloy as refine agent, and its technological parameters were investigated. The optimum conditions are defined., the amount of aluminium is 103 ~ theoretical amount, the addition of refine agent is 100 g, the refining time is 30 min, and the recovery of high vanadium ferrovanadium is 98%. The optimum addition of refine agent is 100 g. If the addition of refine agent is bigger than the optimum addition, the amount of AI in high vanadium ferrovanadium is increased with the refine agent increasing.
