采用优质高铝矾土和莫来石合成料为主要原料，添加蓝晶石、红柱石、硅线石（简称三石）和叶蜡石等作膨胀剂，使用软质黏土作结合剂，再外加适量添加剂，经适宜温度焙烧制成高铝砖，并成功应用于冶炼低碳钢、不锈钢等钢包内村。该砖在高温区使用时产生微膨胀，使钢包内衬具有良好的整体性，从而提高抗侵蚀性。
採用優質高鋁礬土和莫來石閤成料為主要原料，添加藍晶石、紅柱石、硅線石（簡稱三石）和葉蠟石等作膨脹劑，使用軟質黏土作結閤劑，再外加適量添加劑，經適宜溫度焙燒製成高鋁磚，併成功應用于冶煉低碳鋼、不鏽鋼等鋼包內村。該磚在高溫區使用時產生微膨脹，使鋼包內襯具有良好的整體性，從而提高抗侵蝕性。

This paper describes the high alumina brick made of high quality bauxite and mullite compound as major raw materials ,with kyanite ,andalusite ,sillimanite and pyrophyllite as expanding agents,with soft clay as bonding agent ,and with certain amount of additives ,then calcined under appropriate temperature ,which has been sucessfully used for ladle lining to produce low carbon steel and strainless steel .Tiny brick expension appears at the high temperature and allows a good integrity of the ladle lining for a better erosion resistance .
