High alumina refractory brick is product made of bauxite clinker combining some clay which the Al2O3 is more than 48%. Its chemical characteristic tends to neutral. Its capacity of acid slag or alkaline slag is better than clay brick and silicon brick. So high alumina brick can take the place of the clay brick and silicon brick for the purpose to prolong the life of heating equipment, Nowadays the brick is mainly used in blast furnace, hot blast furnace, electric furnace, steel bucket,
