分体式透气砖在钢包砌筑中的应用

APPLICATION OF SPLIT-TYPE AIR BRICK IN LADLE

透气砖寿命是钢包一次包龄的关键限制性因素,通过对标与质地考察决定使用分体式透气砖取代现有的整体式透气砖。介绍了分体式透气砖的结构、优势、砌筑、修补的内容,细化分体式透气砖各个环节的操作,钢包一次包龄由20~23炉提高到38~43炉,备用包投用数量减少,降低了炼钢系统能源消耗及生产成本。

The life of the air brick is the key limiting factor for the first ladle age. Through the inspection of standard and texture, it is decided to replace the integral - type air brick by split - type air brick. The struc- ture, advantages, masonry and repairing contents of the split- type air brick are introduced, and the opera- tion of each link of the split - type air brick is refined. The once teeming ladle age is raised from the 20 - 23 to 38 - 43, so the usage count of spare ladle is reduced, which reduces the energy consumption and produc- tion cost of the steelmaking system.
