攀钢一号高炉炉衬修补实践
LINING REPAIR PRACTICE INPANGANG NO.1 BLAST FURNACE
-
摘要: 对冶炼高钛型钒钛磁铁矿的一号高炉炉身上部进行了压入和喷补造衬。结果表明，炉衬修补后，煤气流分布改善，煤气利用率提高，高炉经济指标提高。压入法造衬的均匀性差，使用寿命较短，不如喷补法造衬的效果好。Abstract: The upper shaft lining of No. 1 blast furnace for smelting high TiO2 bearing vanadic titanomagnetite is repaired by forcing and gunning methods. The results show that the gas flow distribution, the gas utilization and the economic index of blast furnace were improved after lining repair. Lining repaired by forcing process has the poor homogeneity and short service life in comparison with that by gunning process.
