摘　　要：通过含碳球团高温还原法研究还原温度和还原时间对高硅、高铁低品位钒渣的金属化率及钒富集的影响。结果发现,还原时间为60 min、还原温度为1 400℃时效果最佳,Fe的金属化率达80%以上,同时,可将二次钒渣中V2O5的含量提高至46.50%。The influence of reduction temperature and time on metallization rate and vanadium enrichment of the high silicon, high iron and low grade vanadium slag is researched through the carbon pellet high temperature reduction experiment. It is found that the experiment can achieve the best effect when the reduction time are 60 rain and the reduction temperature is 1 400 ℃. Metallization rate of iron is more than 80%. At the same time, content of V205 in the secondary vanadium slag is also relatively high, which can reach 46.50%.
