通过介绍上钢一厂2500m~3高炉工程混铁车内衬修理设施的设计,阐述了有关混铁车内衬的结构组成,并对内衬材料的理化指标、熔损曲线进行了分析比较,对内衬修理各工序作业内容、台位计算、设备选用作了说明,尤其对率先采用转炉煤气烘烤内衬作了创新设计。 By introducing the design of the lined repair facility of 2500m ~ 3 blast furnace in Shangsteel No.1 Steel Plant, the structure and structure of the lined iron mixed vehicle are expounded. The physical and chemical indexes and melting loss curves of the lined material are analyzed and compared. The contents of the operation, the calculation of the position and the equipment selection of the lining repair are described. In particular, the innovative design of the converter gas baking lining is adopted first.
