Kiln AZS Brick
,AZS Brick Corrosion Resistant
,Fused Zirconia Corundum Brick
Leadsun AZS Brick (Fused Zirconia Corundum Brick) is manufactured by melting high-purity alumina powder and zircon sand (containing ~65% ZrO₂ and ~34% SiO₂) in an electric arc furnace, followed by casting into molds and controlled cooling. This oxidation fused-cast process results in a dense, homogeneous structure with exceptional resistance to glass corrosion, thermal shock, and chemical erosion. It is widely used in glass furnaces, non-ferrous metal smelting furnaces, and pure steel furnaces.

- Excellent Glass Corrosion Resistance: Superior resistance to molten glass and chemical attack.
- High Thermal Shock Stability: Maintains integrity under rapid temperature changes.
- High Refractoriness Under Load: Excellent mechanical strength at elevated temperatures.
- Low Porosity & High Density: Dense structure minimizes penetration and erosion.
- Low Exudation of Glass Phase: Reduces contamination in glass melting processes.
- Good Wear & Alkali Resistance: Suitable for harsh industrial environments.
- Certified Quality: Manufactured with approved materials and processes, free from electrode pollution.
-
AZS-33 (ER 1681):
Most widely used in glass kilns. Suitable for walls, bottoms, superstructures, and feeding channels.
-
AZS-36 (ER 1685):
Better corrosion resistance and performance with low pollution characteristics. Used in key areas such as melting pool walls near the hot spot of glass furnaces.
-
AZS-41 (ER 1711):
Best corrosion resistance, performance, and lowest contamination of glass solution. Ideal for critical parts like pool walls, feeding mouth corners, fluid holes, kiln bars, pool bottom bubbling, and all-electric melting furnaces.
- Standard shapes and irregular/custom shapes
- Blocks, bricks, and special designs as per furnace layout
- Sizes and thicknesses tailored to application requirements
- Glass Industry: Glass tank furnaces, regenerators, throat areas, doghouse corners, paving blocks.
- Non-Ferrous Metallurgy: Smelting furnaces for copper, aluminum, zinc, and lead.
- Steel Industry: Ladles, tundishes, refining furnaces.
- Ceramic & Cement: High-temperature kiln linings, burner blocks.
- Chemical & Petrochemical: Reactors, reformers, incinerators.
- Manufactured in compliance with international standards
- All certificates approved for material and performance
- Electrode-free fusion casting technology ensures purity and consistency
