Alumina brick, also known as high-alumina brick or aluminum oxide brick, is a type of refractory brick made from high-purity alumina materials. It has excellent thermal stability, high mechanical strength, and good chemical resistance, making it ideal for use in various high-temperature industrial applications. Here are some common uses of alumina brick:
1.Lining of high-temperature kilns and furnaces: Alumina brick can withstand temperatures up to 1800°C and is commonly used in the lining of high-temperature kilns, furnaces, and other industrial equipment where high thermal shock resistance and abrasion resistance are required.
1.Blast furnace lining:
Alumina brick is highly resistant to slag attack and can withstand the harsh conditions in blast furnaces. It is commonly used in the lining of iron-making blast furnaces, where it provides excellent performance in resisting thermal shock, corrosion, and erosion.
2.Petrochemical industry:
Alumina brick is widely used in the petrochemical industry, where its corrosion resistance and high-temperature stability make it an ideal material for lining reactors, distillation towers, and other high-temperature equipment.
3.Power generation industry:
Alumina brick is also used in the power generation industry, particularly in the lining of coal-fired boilers and gasifiers. The high thermal conductivity and excellent thermal shock resistance of alumina brick allow it to withstand the extreme temperature fluctuations and corrosive gases generated during combustion.
4.Other applications:
Alumina brick can also be used in various other applications, such as in the lining of aluminum smelting cells, calciners, cement kilns, and glass furnaces.
Overall, alumina brick is a versatile and reliable refractory material that provides excellent thermal stability, mechanical strength, and chemical resistance in high-temperature environments.
