在高炉生产中要解决铁口维护问题,除了改进堵铁口的工具外,首先应从改善堵铁口用的炮泥着手。过去国内高炉所用炮泥一般采用耐火粘土、焦粉,涩存粉加水混合制成的,但是近代的大型高炉由于产量大,出铁次数频繁,两次出铁时同的简隔很短,易使铁口耐火蹲迅速侵触而不易推护。有时因铁口炮泥 In the blast furnace production to solve the problem of iron mouth maintenance, in addition to improving the tool blocking iron mouth, first of all should be to improve the use of anti-iron mouth with gun start. In the past, blast furnace mud used in the general use of refractory clay, coke powder, astringent flour and water mixture made, but the modern large-scale blast furnace due to large output, the frequency of frequent outbreaks, the same time the two tapping the same time is very short, easy Tiekou fire squat quickly invaded and not easy to push. Sometimes because of iron taps mud
