High alumina brick is a kind of neutral refractory brick, which has certain resistance to acid and alkali chemical erosion. With the decrease of aluminum content in high alumina brick, acid corrosion resistance is enhanced. High-aluminum brick has the advantages of high temperature resistance, high load softening temperature, high compressive strength, low porosity, strong resistance to solution penetration, etc. It is widely used in the lining of masonry industrial furnaces and thermal equipment, such as Blast furnace, hot blast stove, blast furnace, power plant boiler, electric furnace, etc.
