High alumina bricks are a type of refractory brick made from high-purity alumina and other raw materials. They are widely used in various high-temperature industrial applications due to their excellent thermal stability, mechanical strength, and resistance to corrosion and abrasion.
There are several different types of high alumina bricks, each with specific properties that make them suitable for different applications. Here are some common types of high alumina bricks and their typical applications:
1.High Alumina Fire Bricks: These bricks have high refractoriness, good thermal shock resistance, and strong resistance to acid and alkali slag erosion. They are used in the linings of furnaces, kilns, and other high-temperature equipment in industries such as steel, cement, and glass.
2.High Alumina Insulating Bricks: These bricks have low thermal conductivity, good insulation performance, and lightweight. They are used in the thermal insulation layer of high-temperature equipment, such as kiln hoods, blast furnace stoves, and other thermal insulation areas.
3.Mullite Bricks: These bricks have high refractoriness, excellent thermal shock resistance, and good chemical resistance. They are widely used in the lining of high-temperature furnaces, such as petrochemical cracking furnaces, ceramic kilns, and glass melting furnaces.
4.Corundum Bricks: These bricks have excellent strength, high refractoriness, and strong resistance to wear and corrosion. They are used in harsh environments, such as the lining of carbon black reactors and gasifiers.
5.Phosphate Bonded High Alumina Bricks: These bricks have high strength, good thermal shock resistance, and strong resistance to acid and alkali corrosion. They are widely used in the linings of chimneys, desulfurization towers, and other high-temperature flue gas pipelines in thermal power plants.
In summary, the different types of high alumina bricks have varying properties that make them suitable for different applications in various industries. The selection of the proper type of high alumina brick depends on the specific conditions and requirements of the application.
