Corundum Brick
Corundum brick is a type of refractory brick made primarily from aluminum oxide (Al2O3). It is often used in high-temperature applications, such as furnace linings, kiln walls, and blast furnace stacks, because of its excellent heat resistance and excellent wear resistance. It is usually white or gray in color and can be formed into a variety of shapes and sizes.
- High Strength
- Low impurity content
- High Temperature Resistance
- Good acid and alkali corrosion resistance
Corundum Brick Description
Corundum bricks are a type of refractory brick made from corundum and other raw materials. They are usually used in high temperature environments, such as molten metal, ceramics, petrochemical and electric power industries, where they provide excellent thermal insulation, thermal stability and chemical resistance. Corundum bricks have a number of features that make them ideal for these applications.
The Application Of Corundum Brick
Corundum bricks are widely used in petrochemical industries such as oil refineries and chemical plants. They are highly resistant to corrosion, erosion, temperature and pressure, making them ideal for lining the walls and floors of these facilities.
Corundum brick is a kind of acid refractory material with high alumina content, which is mainly used for the lining of tunnel kiln and other high temperature kiln. It has good heat resistance and high temperature strength and medium thermal shock resistance.
Corundum bricks are the preferred refractory material used in ceramic kilns.It can be used to protect ceramic kiln walls and floors from heat and direct contact with flames, while also reflecting heat back into the kiln to aid in the ceramic firing process.
