摘要
设计了研究钢水中Ａｌ２Ｏ３附着性的高温（１５００～１６００℃）模拟试验装置和方法，对Ｏ＇－Ｓｉａｌｏｎ－ＺｒＯ２复合材料进行了试验，并与Ａｌ２Ｏ３材料作对比。结果表明，Ｏ＇－Ｓｉａｌｏｎ－ＺｒＯ２复合材料的抗Ａｌ２Ｏ３附着能力优于Ａｌ２Ｏ３材料，而Ｏ＇－Ｓｉａｌｏｎ含量越多，抗附着能力越强。探讨了这种复合材料抗Ａｌ２Ｏ３附着的机理，认为主要是Ｏ＇－Ｓｉａｌｏｎ与Ａｌ２Ｏ３在高温下反应生成液相。
Simulative testing equipment and method have been designed for studying the reaction of refractory materials withAl2O3 in steel at high temperature (1500-1600℃). O' -Sialon-ZrO2 composite specimens have been tested together withAl2O3 specimen for comparison. The results indicate that O'-Sialon-ZrO2 composite malerials are superior to Al2O3 material in term of resislance to Al2O3 despition, i. e. ante-cloggingl the higher the o'-Sialon content, the better the anticlogging behavior. The mechanism of the improved resistance to Al2O3 despition of O'-Sialon-ZrO2 compeities has bendiscussed. It is considered to be mainly due to the reaction of O'-Sialon with Al2O3 to form liquid phase at 1500-1600℃.
