摘要：

介绍了目前国内干熄焦炉斜道区用耐火材料的主要材质，并从微观和宏观角度分析了柱部砖损毁的主要原因，对目前使用的莫来石碳化硅砖、莫来石红柱石砖、氮化硅结合碳化硅砖和新研发的低内应力莫来石红柱石砖的应用、试验情况进行了对比分析。斜道区柱部砖其良好的热震稳定性和耐磨性是满足柱部砖长寿化的主要条件。新型高温低内应力莫来石红柱石砖具有极低的高温内应力、优良的热震稳定性、良好的耐磨性、较低的体积密度等优点，能够很好的满足干熄焦炉柱部耐材长寿化的需求。

Abstract:

This paper introduces the main materials of refractories used in flue of CDQ in China,analyzes the main causes of brick damages of partition wall from microscopic and macroscopic angles.From the application and test of mullite-silicon carbide brick,mullite-andalusite brick,silicon nitride bonded silicon carbide brick and newly developed low internal stress mullite-andalusite brick are compared and analyzed.It is pointed out that improving the thermal shock stability and good abrasion resistance of the partition wall bricks can satisfy longevity,and a new type of high temperature and low internal stress mullite-andalusite brick has the advantages of very low internal stress,excellent thermal shock stability,good abrasion resistance and low bulk density and so on,which can meet the longevity requirement of partition wall refractories in CDQ.

Key words: CDQ, Partition wall brick, Longevity, Mullite-andalusite brick, Thermal shock stability
