Reduce Downtime with High-Performance AZS Series Refractory Products
1. Zirconia: ≥ 20%
2. Standard Size: 230*114*65mm
3. Benefits:
• Combat alkali corrosion
• Reducing downtime and total operational cost
The sintered zirconia corundum brick AZS series products(including models such as AZS-20, AZS-30, AZS-33, etc.) are professional refractory materials developed for special working conditions in glass furnaces. This series of products is divided into two types according to production process and shape characteristics: Type A is standard machine-pressed products(such as AZS-20A), and Type B is special-shaped cast products(such as AZS-20B). These products have excellent resistance to alkali vapor corrosion, outstanding thermal shock stability(1100℃ water quenching cycle ≥20 times), and good high-temperature volume stability. Main application areas include glass furnace hot repair projects, hot replacement of key components such as nozzle bricks, high-temperature zones in the upper part of regenerators, and areas with frequent thermal shock such as port necks.
Note: Type A products have higher dimensional accuracy(±0.5mm); Type B products adopt special casting processes and can produce complex special-shaped pieces.This series of products is particularly suitable for maintenance and key part repairs of float glass and container glass furnaces.
1. Glass Industry
Primary Application: Critical linings in glass melting furnaces, especially the superstructure, doghouse corners, and regenerator upper walls.
Key Advantage: Exceptional resistance to corrosion by alkali vapors and glass batch dust, ensuring long campaign life.
2. Metallurgical Industry
Secondary Steelmaking: Used in ladle slag lines and walls for refining high-grade steel.
Non-Ferrous Metals: Linings for furnaces contacting molten aluminum and copper alloys.
3. Ceramic & Chemical Industries
High-Temperature Kilns: As kiln furniture (setters, slabs) and combustion zone linings.
Severe Environments: Reactor linings for chemical waste incineration and highly corrosive processes.
