提高料钟的使用寿命和缩减检修工期是高炉连续生产的重要措施。本文强调:大钟室具有低温环境,使小钟可以采用橡胶软密封,这是提高料钟使用寿命,实现高压操作的根本保证为此目的,解除大钟密封、上移密封室、冷矿入炉,采取大钟隔热保温和炉顶洒水技术。本文介绍了料钟检修新方案,对改造我国马基炉顶有重要的现实意义。 Improve the service life of bell and reduce maintenance time is an important measure for continuous blast furnace production. This paper emphasizes: the bell room has a low temperature environment, so that the small bell can be soft rubber seal, which is to improve the service life of the bell, the fundamental guarantee for high-pressure operation To this end, lifting the bell seal, Furnace, take big bell insulation and roof sprinkler technology. This article introduces a new program for maintenance of material bell, which has important practical significance to transform the roof of our country.
