Used AZS bricks for glass furnace bottom and wall
Recycled AZS brick for Glass Furnace bottom is remove from glass kiln, and kept in good condition .We can reprocess waste AZS grog scrap according to your specification or requirements.
Fused zirconia corundum brick(also known as AZS brick) is made by the process of completely melting the raw material firstly and then cast in the mold, finally cooling, solidification. This product shrinkage should be paid special attention in using, which is caused during the volume shrinkage in the condensation process. Fused zirconia corundum brick casting methods divide into ordinary casting, tilting casting, no shrinkage casting and quasi-no shrinkage casting. AZS products with different casting methods can meet the use requirements of various parts in the ceramic frit furnace, spent flower alkali furnace, glass kiln.
There are two using ways of Recycled AZS brick for Glass Furnace bottom :
1. large piece of recycled waste AZS gorg scrap, generally used to re-polish and reprocess to be new brick, can be used in the glass kiln, that will save costs.
2. small piece of waste AZS grog Scrap, because of small size, it can only be used to break into unshaped material.
Recycled AZS brick for Glass Furnace bottom
Our Recycled AZS brick are cleared by eliminating the glass slag from surface, with chemical composition and physical indicators same as new products.It is high efficient and can save costs for customers.

Characteristics of fused zirconia corundum bricks for glass kiln
Ordinary glass melting furnace wall bricks generally use a shallow pool structure with a thickness of 250mm and a height of about 1350mm. The wall bricks are made of fully oxidized obliquely cast fused zirconia corundum. Generally, 36#AZS is used for the melting zone, 33#AZS is used for the clarification zone, and 41#AZS is used for the corner. Under the same quality conditions, the high-grade bricks are more resistant to erosion, but the high-grade bricks are prone to bursting when the residual amount of erosion is less than 50 mm, and also designed as a layered structure or a deep pool structure. With the increase of kiln age and the use of lower layer insulation and bubbling, the erosion of the lower pool wall is more, and it is not easy to inspect. Some manufacturers have thinned the lower pool wall when discharging water, so the quality of the lower pool wall should also be taken seriously. In order to gradually extend the life of domestic glass melting furnaces, the production technology of fused zirconium corundum bricks can be improved, and the use of pool bricks is also essential.
