耐火材料炉衬的寿命决定着高炉的炉役寿命。目前，世界上有两大不同的设计思想。一种采用昂贵的炉衬来完成整个炉役。另一种采用价廉一点的炉衬，并在炉役期间安排一次或两次中修来修补耐火材料特别是炉腹和炉身部位。本文将介绍几座高炉在炉役期间的生产数据和有关炉役寿命的数据资料。以及炉缸等部位使用的高级耐火材料，如微孔碳砖等。 The life of refractory lining determines the service life of blast furnace. At present, there are two different design ideas in the world. One uses expensive linings to complete the entire furnace. The other uses a lighter lining and arranges one or two intermediate repairs to repair the refractory material, particularly the bosh and the shaft, during the service. This article will introduce several blast furnace production data during the campaign and data on the life of the furnace. As well as high-grade refractories used in hearth and other parts, such as microporous carbon brick.
