AZS Ramming Material

AZS ramming mix utilizes high-quality granular materials and micropowders matched to the composition of fused AZS bricks, combined with an efficient composite bonding system through dry mixing. Its design philosophy centers on achieving “material performance compatibility and enhanced construction flexibility,” with core advantages including:

Exceptional erosion resistance: Inherits AZS material's superior resistance to molten glass and alkali vapor erosion, ensuring overall lining durability.

Seamless monolithic structure: On-site ramming eliminates weak brick joints, forming a continuous, dense working surface that effectively prevents erosion medium penetration.

Superior high-temperature volume stability: Forms stable ceramic bonds at elevated temperatures with minimal volume shrinkage, high structural strength, and no risk of spalling.

Flexible Construction Adaptability: Dry installation enables high-temperature resistance without baking, ideal for hot repairs and irregular-shaped areas.

High Construction Efficiency: Simplified masonry process suits large-scale installations or rapid repairs, minimizing furnace downtime.

Key Technical Parameters:

- Material Grade: AZS-33, AZS-36 (optional)

- Primary Chemical Composition: Matches corresponding AZS brick grades (ZrO₂, Al₂O₃, SiO₂)

- Bulk Density (after ramming): ≥ 3.0 g/cm³

- Maximum Service Temperature: ≥ 1700°C

- Installation Method: Dry ramming or vibratory compaction

AZS rammed refractories are widely used in the glass industry and other high-temperature applications requiring monolithic, seamless, and highly erosion-resistant linings. Primary applications include:

1. Leveling and sealing layers for glass melting furnace hearths: Used for monolithic leveling layers atop large hearth bricks, joint sealing layers, and sealing fill around electrodes.

2. Complex structures and corners: Difficult-to-brick areas such as feed port corners, around liquid drainage holes, furnace bottom ledges, and bubble generator peripheries.

3. Hot maintenance and emergency repairs during furnace operation: Online hot repairs for localized erosion defects on tank walls, bottoms, and other areas.

4. Feed Chutes and Distribution Chutes: Serves as integral lining material for chute bottoms or as dense filling material for side walls.

5. Other High-Temperature Furnaces: Used for constructing or repairing integral linings in similarly demanding conditions within metallurgical, chemical, and other industries.
