武钢四座高炉(容积分别为1386,1436,1513,2516米~3)炉身寿命一般仅3～4年一代炉役中需要进行2—3次中修。因此炉身下部和炉腰是目前武钢高炉寿命短的关键部位。影响炉身寿命的原因很多,如原燃料条件、冷却结构和冷却方式、内衬材质、操作和维护等,且互相制约,本文侧重讨论结构 WISCO four blast furnaces (volume respectively 1386,1436,1513,2516 m ~ 3) furnace body life is generally only 3 to 4 years need to be 2-3 times in the furnace repair. Therefore, the lower part of the shaft and the waist is the key part of the short life of the blast furnace in WISCO. There are many reasons that affect the life of the shaft, such as raw fuel conditions, cooling and cooling methods, lining material, operation and maintenance, and mutual restraint, this article focuses on the structure
