摘　　要：对狭缝式透气砖在大型精炼钢包中的损毁原因进行了分析 ,热应力和强大的冲刷磨损作用是两个主要因素。对狭缝式透气砖使用中影响其透气性能的各种因素加以分析后认为 ,除了透气砖本身狭缝的尺寸、钢水温度、钢水种类外 ,操作过程和使用中受保护的程度也是影响透气性能的重要因素。The wear reason of slit purging plug used in the large refining ladle has been analyzed in detail in the paper, that is the thermal stress and strong erosion and abrasion. After analyzing, it is concluded that the operation process and the degree of being protected of the plug are the main factors affecting the performance of the plug besides the slit size of the plug, the temperature and the sort of the liquid steel.
