鞍钢九号高炉炉容983米~3,1979年大修对三座内燃式热风炉作了较全面的改造,1981年10月建成正式投产.其特点是:1. 拱顶的改造:将原有半球形拱顶改为锥形拱顶,由园锥台和120°球顶两部分组成,使其结构稳定.由于锥顶热流反射的焦点抬高了两米多,对格砖表面的损坏将会得到改善.在气流分布方面,投产前作了气流分布的冷态测定,并与半球顶的热风炉进行了比较,结果表明较原拱顶气流分布得到了较大改善,从而证实该热风炉拱顶改造设计是成功的.在施工中,拱顶由大块砖改为小
Anshan Iron and Steel Company No. 9 blast furnace capacity of 983 m ~ 3, 1979 overhaul of the three internal combustion stove made a more comprehensive transformation, completed in October 1981 formally put into operation. Its features are: 1. Vault renovation: the original The hemispherical dome is replaced by a conical dome consisting of a conical frustum and a dome of 120 ° so that its structure is stable.Due to the fact that the focal point of the cone heat flux rises by more than two meters, Will be improved in the air distribution, made before the cold flow distribution of the measured and compared with the top of the hemispherical stove were compared, the results show that the distribution of the original vortex airflow has been greatly improved, which confirmed that the hot air stove arch The top renovation design is successful in the construction, the vault from big brick to small
