摘　　要：对目前钢包用透气砖的工作环境、狭缝式透气砖存在的问题及弥散式透气砖的特点进行了介绍,并对弥散式透气砖和狭缝式透气砖在使用过程中的透气量及底吹压力进行了对比。结果表明:弥散式透气砖对吹扫的依赖性较小,使用过程中透气性优良,能够满足现场的工况条件要求。Working environment of the permeable brick for ladle,the problems of the slit permeable brick and the dispersion brick were introduced,and the ventilation quantity and bottom blow pressure in the application of diffused permeable brick and slit permeable brick were compared. The results indicated the dispersion brick with good permeability less dependence on the scavenging,which can satisfy the needs of the site.
