Corundum mullite bricks play an important role in glass kilns due to their unique combination of properties. The following are their main application features and advantages:

1. High temperature resistance and thermal stability: Corundum mullite bricks have excellent high temperature resistance and can maintain structural stability in the high temperature environment of glass melting, prevent deformation or cracks caused by thermal stress, and help improve the operating safety of glass kilns and the service life of kilns.

2. Low thermal expansion and creep: This type of brick has a low thermal expansion coefficient and small creep, which means that under long-term high-temperature operation, they can maintain dimensional stability and reduce stress concentration caused by thermal cycles. They are particularly suitable for use as complex structural parts of glass kilns, such as crowns and side walls.

3. Corrosion resistance: Although corundum mullite bricks may be corroded to a certain extent in highly alkaline environments, they show good corrosion resistance in many areas of glass kilns, especially those that are in direct contact with molten glass but are less corroded by alkali vapor. The combination of mullite phase and corundum phase can resist chemical erosion in glass melt and flue gas to a certain extent.

4. High refractoriness under load and long service life: The high refractoriness under load of corundum mullite bricks means that they are not easy to soften and deform while bearing high temperature and load, thereby extending the replacement cycle of the kiln lining and reducing maintenance costs and production downtime.

Application in special parts: In glass kilns, corundum mullite bricks are often used in parts such as flow channels, flow channels, and pool walls, which require refractory materials to have good thermal shock resistance and be able to withstand mechanical wear and chemical erosion caused by the flow of glass liquid.

Customized solutions: According to the specific needs of glass kilns, corundum mullite bricks can be adjusted in composition and structural design, such as adding alkali-resistant components or optimizing the microstructure of bricks, to further improve their applicability under specific working conditions.

In summary, corundum mullite bricks are one of the indispensable high-performance refractory materials in the construction and maintenance of glass kilns due to their characteristics of high temperature resistance, low thermal expansion, corrosion resistance and long life, and play an important role in ensuring glass production efficiency and product quality.
