摘　　要：在攀钢钒钛资源综合利用中试线开展钢包提钒生产实践,对影响提钒过程的温度控制、供氧量、扒渣、铁水成分等影响因素进行了分析,并对出现的问题提出了解决办法。实际生产条件下,控制熔池温度为1 450～1 500℃、保持底吹畅通、供氧量达到1 400 m3/h、适时加入冷却剂可获得较好的提钒效果,目前已提取出V2O5含量高于7%的钒渣。Recovery of vanadium from molten iron in ladies was carried out in a Pangang pilot plant for comprehensive utilization of vanadium and titanium resources, and influencing factors vanadium recove- ring process, including temperature, oxygen supply, slag skimming and Si content in the molten iron, were analyzed. The results show that in practical production, good results can be achieved with tempera- tures of molten bath at 1 450 - 1 500 ℃, smooth bottom blowing, oxygen supply at 1 400 m3/h and time- ly addition of adequate coolant. So far, vanadium slag with V2O5 content above 7% has been obtained.
