我国现有地坑式侧吹转炉车间厂房高度都较低,行车轨面标高只有8～9米左右。如何利用现有厂房改建为顶吹氧气转炉车间是大家关心的问题。我厂顶吹氧气转炉车间是1965年改建成的。原来是地坑式侧吹转炉车间,行车轨面标高为9.04米,而顶吹氧气转炉喷枪提升高度要求较高,厂房高度就显得不够,如 China’s existing pit side blowing converter workshop plant height are lower, driving rail elevation of only 8 to 9 meters. How to use the existing plant converted into top-blowing oxygen converter workshop is everyone’s concern. My factory top blowing oxygen converter workshop was converted into 1965. The original pit side blowing converter workshop, driving rail elevation of 9.04 meters, while the top blowing oxygen lance height requirements higher, the height of the plant is not enough, such as
