1 引言 经过40年的发展,柳钢逐步形成了具有4座300m~3级高炉、年产100万t生铁生产能力的地方骨干企业。但由于种种原因,铁水罐的配置却没有及时跟上生产发展的需要。仅有的18个65t梨形铁水罐中,就有3个铁水罐长期轮流安排在外大修,实际上只有15个铁水罐用以维持简单再生产。我们对铁水罐虽然进行了加高改造,使容铁量增大到75t,但仍与实际生产需要不相匹配,加上受
1 Introduction After 40 years of development, Liuzhou Steel gradually formed a backbone enterprise with 4 300m ~ 3 blast furnaces and an annual output of 1 million t pig iron. However, due to various reasons, the configuration of the hot metal tank did not keep up with the needs of production and development. Of the only 18 65t pear-shaped hot metal jars, three hot metal ladle vessels were scheduled to be permanently overhauled, with only about 15 hot metal tanks maintained for simple reproduction. Although we carried out the improvement of the hot metal tank to increase the capacity of iron content to 75t, but still incompatible with the actual production needs, coupled with
