AZS Bricks
Product Information
AZS block is also called fused zirconia corundum brick which contains Al2O3-ZrO2-SiO2. The fused cast AZS block is made of pure alumina powder and zircon sand (consisting of 65% zirconia and 34% SiO2). After the alumina powder and zircon sand are melted in an electric furnace, they are cast into various molds and cooled down to become white solids.
Features
1. High refractoriness
2. Good thermal shock resistance
3. Good creep-resisting property
4. Good chemical stability
5. Good high temperature strength and volume stability
6. High erosion resistance

AZS 33
|
33%
|
The dense microstructure of AZS33 makes the bricks have good resistance to glass liquid erosion, and it is not easy to produce stones or other defects in the glass kiln. It is a widely used product in glass melting furnaces, and is mainly suitable for the upper structure of the melting pool, the pool wall brick and paving brick of the working pool, and the forehearth, etc.
|
|
AZS 36
|
36%
|
In addition to having the same eutectic as AZS33, AZS36 bricks have more chain-like zirconia crystals and lower glass phase content, so the corrosion resistance of AZS36 bricks is further enhanced, so it is suitable for glass liquids with faster flow rates. or higher temperature areas.
|
|
AZS 41
|
41%
|
In addition to eutectics of silica and alumina, it also contains more uniformly distributed zirconia crystals. In the zirconium corundum brick system, it has good corrosion resistance. Therefore, key parts of the glass furnace are selected to balance the life of these parts with other parts.
