Description
Corundum mullite bricks are refractory materials with high strength, excellent thermal shock resistance and good chemical stability. Corundum mullite refractory bricks are widely used in high-temperature applications such as furnaces, kilns and other industrial applications requiring resistance to high temperatures and thermal shock. It is made from a mixture of corundum (aluminum oxide, Al2O3) and mullite, both of which are high-purity, high-strength materials with excellent thermal stability.
Features
High Temperature Resistance
Corundum mullite bricks can withstand temperatures up to 3272°F (1800°C), making them ideal for use in high-temperature furnaces and kilns.
Excellent Thermal Shock Resistance
Corundum mullite bricks can withstand rapid temperature changes without cracking or fracturing, making them suitable for applications with frequent temperature fluctuations.
High strength
Corundum mullite bricks have high compressive strength and can withstand heavy weight, so they are suitable for applications with high pressure.
Good chemical stability
Corundum mullite bricks are resistant to most chemicals and can withstand the erosion of corrosive substances, ideal for use in harsh industrial environments.
Low thermal conductivity
Corundum mullite bricks have low thermal conductivity, which can effectively insulate the heat transfer and have good heat preservation ability to keep the heat in the furnace or kiln.
Stable under high pressure
Corundum mullite bricks are stable under high pressure, making them ideal for use in applications with high pressure, such as the production of ceramics and other materials.
Application
Corundum mullite bricks are commonly used as a lining material for steel furnaces and ladles, as well as for intermediate containers (i.e., containers that hold the molten steel before it is poured into the final product).
Corundum mullite bricks are used as a lining material in furnaces for melting glass and in regenerators for preheating combustion air.
Ceramics production
Corundum mullite bricks are often used as lining material for kilns firing ceramics, as well as for combustion chambers and heat accumulators for preheating combustion air.
Petrochemical refining
Corundum mullite bricks are used in reactors and furnaces in petrochemical refineries, where they are exposed to high temperatures and corrosive substances.
Incineration
Corundum mullite bricks are used in incinerators for waste treatment, where they are exposed to high temperatures and corrosive substances.
Power generation
Corundum mullite bricks are used in combustion chambers and boilers in power plants, as well as in gasifiers for the production of synthetic fuels.
