High alumina bricks are important refractory materials and are widely used in various high-temperature environments due to their high aluminum content and excellent fire resistance, corrosion resistance and thermal stability.
Specifically, it is mainly used in the following scenes.
Steel industry: High alumina bricks are widely used in the steel industry, mainly as lining for equipment such as blast furnaces, converters and electric furnaces. These devices need to withstand very high temperatures and pressures during operation, as well as erosion caused by slag fluids. High alumina bricks, with excellent refractoriness and slag resistance, can withstand these harsh working conditions and ensure the stable operation of the equipment.
Non-ferrous metallurgy: In the non-ferrous metal smelting process, high alumina bricks are also widely used for lining equipment such as reverberatory furnaces and resistance furnaces. These devices need to withstand high temperatures and corrosive environments, and the excellent properties of high-alumina bricks make them an ideal choice.
Chemical industry: In the chemical industry, alumina bricks are mainly used for lining equipment such as high-temperature reactors, decomposition furnaces and incinerators. These equipment generally need to withstand high temperatures, high pressures and highly corrosive environments. The fire resistance and corrosion resistance of alumina bricks meet these requirements and ensure smooth production processes.
Ceramic industry: High-alumina bricks are also widely used in the ceramic industry, mainly in ceramic kilns, high-temperature tunnel kilns and other equipment. High-alumina bricks are widely used in the ceramic industry because of their high refractoriness and heat resistance, thus helping to improve the quality and production of ceramic products.
Building materials industry: High alumina bricks are also used in cement kilns, glass furnaces and other facilities to provide a stable lining for these high-temperature structures.
Power and waste incineration industry: Alumina bricks also play an important role in facilities such as coke ovens, fluidized bed boilers, coal-fired furnaces and waste incineration plants. In addition, alumina bricks are classified into different types based on their alumina (Al₂O₃) content and can be used in different scenarios.
Low and high alumina bricks: Al₂O₃ content is 48-70%, they are mainly used for lining blast furnaces, hot blast furnaces, electric furnaces, blast furnaces and reverberatory furnaces.
High alumina bricks: Al₂O₃ content is 70%-85%, mainly used for lining blast furnaces, furnaces, steel crucibles and high-temperature equipment in the chemical and petroleum industries.
High alumina corundum bricks: Al₂O₃ content is 85-95%, with the characteristics of high refractoriness, high softening point under load, slag resistance, high heat resistance, low creep speed, etc., mainly used in industries such as steel, non-ferrous metals, chemicals, petroleum, ceramics, etc.
High alumina bricks are widely used in many industries due to their excellent refractoriness and corrosion resistance, and are ideal for lining high-temperature equipment.
