Common Applications of High Alumina Bricks For furnaces And Kilns:
 
Blast Furnaces: High alumina bricks are used in the lining of blast furnaces, which are crucial in the production of iron and steel. They can withstand the extremely high temperatures and harsh conditions inside the furnace.
 
Kilns: They are used in various types of kilns, including rotary kilns, tunnel kilns, and shuttle kilns, which are employed in industries like ceramics, cement, and glass manufacturing.
 
Incinerators: High alumina bricks are used to line the combustion chambers of incinerators. This is because they can withstand the high temperatures generated during the waste incineration process.
 
Petrochemical Industry: They find applications in the lining of reactors and other equipment used in the production of chemicals, petrochemicals, and fertilizers.
 
Furnace Lining: They are used in the lining of industrial furnaces, including those used for heat treatment, metal smelting, and other high-temperature processes.
 
Glass Industry: High alumina bricks are utilized in the construction of glass tanks, which are essential components in the production of glass.
 
Steel Industry: They are used in steel ladles, ladle covers, and other parts of the steel-making process that are exposed to high temperatures and aggressive slag.
 
Cement Industry: High alumina bricks are used in the lining of cement rotary kilns, where they help maintain high temperatures necessary for the clinker formation.
 
Foundries: They are used in various applications within foundries, including the lining of coreless induction furnaces, electric arc furnaces, and other high-temperature equipment.
 
Power Plants: High alumina bricks are used in boilers, combustion chambers, and other high-temperature zones within power plants.
