AZS feedline bricks are manufactured using a precisely controlled electric melting process based on an optimized formulation within the ternary Al₂O₃-ZrO₂-SiO₂ system. Their unique performance characteristics include:
Exceptional erosion resistance: High zirconia (ZrO₂) content forms a stable crystalline structure, effectively resisting chemical corrosion and physical erosion from molten glass。
Minimal leaching characteristics: Strictly controlled glass phase content prevents contamination of molten glass, ensuring product quality。
Superior thermal shock stability: Withstands thermal stresses caused by temperature fluctuations in the feed channel。
Precise dimensional control: CNC machining ensures masonry accuracy and tight joint integrity。
Key Technical Parameters:
Zirconia content: 33%-41% (Optional)
Bulk density: ≥3.75 g/cm³
Apparent porosity: ≤1.5%
Room-temperature compressive strength: ≥150 MPa
Maximum operating temperature: 1750°C
