随着高炉炉容大型化的发展,目前世界上已出现了4000～5000米~3级高炉,高炉出铁口每昼夜通过的铁水量达到7000～10000吨,炉顶压力达到2.5公斤/厘米~2。在高炉冶炼不断强化的同时,对铁口工作提出了越来越高的要求。有水炮泥很难适应这一要求,因而我厂1971年在学习兄弟单位好经验的情况下,首先在三高炉成功地使用了无水炮泥。随后五高炉等其它高 With the development of large-scale blast furnace capacity, the world has emerged 4000 ~ 5000 m ~ 3 blast furnace blast furnace tapholes every day and night through the iron reached 7000 ~ 10000 tons, top pressure reached 2.5 kg / cm ~ 2. In the blast furnace smelting continue to strengthen at the same time, the work of Tiekou put forward higher and higher requirements. It is very difficult to meet this requirement with water gun clay. Therefore, in 1971, our factory successfully used anhydrous mud clay in the third blast furnace when learning the good experience of our brother unit. Followed by five other high blast furnace
