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
The smelting of high-titanium vanadium-titanium magnetite No. 1 blast furnace upper pressed into and make up lining. The results show that after the lining is repaired, the gas flow distribution is improved, the gas utilization rate is raised and the economic index of the blast furnace is improved. Press-in liners made of poor uniformity, shorter service life, as good as the effect of the law made lining gun
