Description of Corundum Mullite Bricks:

Corundum mullite bricks are a type of refractory brick that is made from a mixture of alumina (Al2O3) and mullite (3Al2O3-2SiO2).  Corundum mullite brick is made of high-purity fused aggregate, ultrafine powder and composite admixture through high pressure forming and high temperature sintering. It has excellent characteristics such as high temperature resistance, erosion resistance, corrosion resistance and thermal shock stability.

Applications: The main uses of chrome Corundum Mullite Bricks include:
* Steelmaking: Corundum mullite bricks are used in the lining of steelmaking furnaces to protect the furnace walls from the high temperatures and corrosive environment.
* Glassmaking: Corundum mullite bricks are used in the lining of glassmaking furnaces to protect the furnace walls from the high temperatures and corrosive environment.
* Cement production: Corundum mullite bricks are used in the lining of cement kilns to protect the kiln walls from the high temperatures and corrosive environment.
* Other applications: Corundum mullite bricks are also used in a variety of other high-temperature applications, such as in the production of ceramics, refractories, and abrasives.

The advantages of using corundum mullite bricks:

1.High refractoriness: Corundum mullite bricks can withstand higher temperatures than other types of refractory bricks.

2.Good thermal shock resistance: Corundum mullite bricks can withstand sudden changes in temperature without cracking or breaking.

3.Chemical inertness: Corundum mullite bricks are chemically inert and will not react with other materials.

4.Durability: Corundum mullite bricks are durable and can withstand a lot of wear and tear.
