High alumina bricks are a type of refractory brick with high alumina content, typically above 48%. They are widely used in various high-temperature industrial applications due to their excellent performance in resisting heat and chemical corrosion. The different uses of high alumina bricks are as follows:

1. Blast furnace: High alumina bricks are used in the hot blast stove and combustion chamber of blast furnaces due to their high thermal shock resistance and good slag resistance.

2. Steelmaking: High alumina bricks are also used in various steelmaking processes, such as steel ladles, tundishes, and electric arc furnaces, due to their high temperature resistance and good resistance to chemical erosion by molten steel or slag.

3. Incinerators: High alumina bricks are used in waste incinerators and hazardous waste treatment furnaces due to their excellent resistance to acid and alkali gases, high-temperature stability, and mechanical strength.

4. Cement industry: High alumina bricks are used in cement kilns and preheaters due to their high-temperature resistance and good wear resistance against raw materials and clinker.

5. Petrochemical industry: High alumina bricks are used in cracking furnaces, reforming furnaces, and other high-temperature reaction vessels in the petrochemical industry due to their high-temperature resistance and good thermal shock resistance.

6. Glass industry: High alumina bricks are used in glass melting furnaces, regenerators, and checker bricks due to their excellent thermal shock resistance, high-temperature strength, and corrosion resistance.
