摘要 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。 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.
