1,Description:
Magnesium Zirconium Checker Brick used in regenerator of glass furnace must have smooth air flow, high temperature resistance, resistance to air wash and erosion, and excellent high temperature stability of products. According to the shortcomings of sintered magnesia brick used before, magnesia-chrome brick and short service life, our factory has developed higher quality magnesia-zirconia lattice brick,the product has little high temperature deformation and better thermal shock stability,the remarkable feature is that It is superior in corrosion resistance and high temperature resistance of air component, so the service life is longer, up to 8 years. Our factory produces this product with strict process control, quality system control, complete laboratory testing, to ensure product quality, the product has been well received since the use of users. At present, domestic glass factories have completely replaced sintered magnesia bricks with this product, which has been exported to many countries.

3,Production process of Magnesium Zirconium Checker Bricks:
Select high-purity fused magnesia, magnesium zirconium composite, reasonable ratio, mixing, high tonnage brick press molding and drying. Finally, it is fired at a high temperature of about 1650 ℃. The main mineral phases formed in the firing process of the product: periclase, forsterite and clinopyrite. Superior performance at high temperature
4,Application and characteristics:
1) The product is mainly used in the upper and middle parts of regenerator of glass kiln. It has no blockage and collapse and has a service life of 8 years.
2) The products have good corrosion resistance to alkali metals, oxides and sulfides.
Site of use:
mainly used in regenerator of glass furnace
Compared with magnesia brick, the product has higher load softening temperature, better thermal stability, especially better alkali vapor permeability and better conductivity.
5.Good feedback of product use effect,the products have been exported to Australia, the United States, Kenya
