摘　　要：本文应用化学分析、偏光显微镜、扫描电镜、电子探引及X射线衍射分析等研究了国产33#熔铸AZS砖在平板玻璃液中的侵蚀层.并在1 500℃无玻璃液侵蚀条件下,进行了模似实验,考察了原砖的晶相变化规律.结果表明:33#熔铸AZS砖的损毁实质上是多晶相材料的溶解过程.斜锆石集合体形态不理想是国产砖损毁过快的主要原因.The corrosion layers of domestic 33~# fused cast zirconia—alumina —silica bricks are studied by means of chemical analysis,polarizing microscope,scanning electron microscope, electron microprobc and X-ray diffraction analysis.At the temperature of 1500℃ and without molten glass corrosion,the simulated tests arc carried out to investigate the variations of crystalline phases in unused bricks.The results show that the corrosion of 33~# fused cast zirconia-alumina-silica bricks is essentially the dissolving process of multi-crystal phases material.The unsatisfactory morphology of zirconia aggregate in domestic bricks is the main cause which accelerates the corrosion rate.
