摘　　要：针对攀钢目前含钒铁水的工艺流程和含钒转炉钢渣中V2O5 含量,提出了从含钒钢渣提钒的新的技术思路和工艺,并对新工艺的关键环节———含钒钢渣冶炼和高钒铁水提钒进行了试验研究。结果表明:采用矿热炉冶炼含钒钢渣,生铁中钒的质量分数达7 45%,对含钒生铁进行提钒,钒渣中V2O5 的质量分数达35 06%,实现了钒资源的有效提取和综合回收。In view of the existing treatment process of hot metal containing vanadium and V_2O_5 content in BOF slag at Pangang, a new process of vanadium recovery from BOF slag containing vanadium oxide was put forward. The experiments of smelting BOF slag containing vanadium oxide and recovering vanadium from hot metal with high vanadium have been carried out. The results showed that the vanadium content in pig iron is 7.45% when slag containing vanadium oxide is smelted in submerged-arc furnace, and V_2O_5 content in vanadium slag is 35.06% after recovering vanadium from pig iron. In this way, vanadium can be recovered significantly.
