一、前言沸腾钢的封顶方法对沸腾钢质量特别是头部质量关系很大。封顶方法有化学封顶和机械封顶两种。武钢1959年开工到1964年,采用敞口模打渣压盖封顶,1964年以后改用瓶口模,籍以改进质量提高收得率。文化革命中,工人自动在瓶口模中以硅铁代替压盖封顶,1972年后干脆改为敞口模化学封顶至今。在化学封顶中武钢科技人员作了不少工
First, the prelude Boiling method of steel top quality of boiling steel, especially the head of a great relationship. There are two types of capping methods: chemical capping and mechanical capping. WISCO was started in 1959 to 1964, using an open-ended mold to tap the top of the lid. After 1964, it was switched to a bottle-shaped mold to improve the quality and increase the yield. In the cultural revolution, workers automatically replaced the gland with capitals in the bottle mouth molds, and after 1972 they simply switched to open-top chemical cap so far. Wuhan Iron and Steel Science and Technology personnel made a lot of work in the chemical cap
