Abstract:

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.
