| 摘 要： | 对含钛高炉渣，铁显微结构的研究表明，攀钢高炉随冶炼强度的提高，炉渣组成发生变化，渣中TiC,TiN,Ti(C,N)含量减少，影响护炉效果，含钒钛的铁水中含有TiC,TiN,Ti(C,N),对护炉起着很大作用，因此钒钛矿护炉不单是含钛渣完成的，也有含钒钛铁水的作用。

| Abstract: | The composition of blast furnace (BF) slag at PZH Steel was changed with increasing of smelting intensity. The microstructure analysis of hot metal and slag containing Vanadium-Titanium show that the TiC,TiN,Ti(C,N) contents were decreased and it resulted in negative effect on BF lining protection. The TiC,TiN,Ti(C,N) containing Vanadium in the iron phase of hot metal play an important role in protecting BF lining. The V-Ti-bearing iron ore is used for BF lining protection not only result from the slag but also performance of the hot metal. |
