AZS Fire Clay

AZS Fireclay utilizes carefully selected electrofused AZS aggregates and fine powders with compositions similar to the main bricks. Through scientific grading and composite modification, it ensures synchronous sintering with AZS bricks during high-temperature use, forming a robust monolithic structure. Its core performance advantages include:

Exceptional Performance Compatibility: Chemical composition and thermal expansion coefficient highly match AZS bricks, preventing cracking or erosion/penetration caused by interface performance differences.

Superior Erosion and Permeability Resistance: The ceramic bonding phase formed at high temperatures effectively resists erosion and permeation of molten glass and alkali vapors along brick joints, protecting vulnerable areas.

High Bond Strength and Volume Stability: Provides robust bonding strength from ambient to high temperatures with low shrinkage during drying and firing, ensuring structural integrity of masonry.

Excellent workability: Optimal water content, good spreadability, water retention, and plasticity facilitate construction, ensuring full and uniform mortar joints.

Key Technical Specifications:

- Material Grade: Compatible with AZS-33, AZS-36, AZS-41

- Chemical Composition: Identical to corresponding AZS brick grades

- Particle Size: ≤ 1.0mm

- Setting Time: Adjustable to meet masonry requirements

- Room Temperature Bond Strength (after drying at 110°C): ≥ 1.0 MPa

- High-Temperature Flexural Bond Strength (1400°C, 3h): ≥ 3.0 MPa

- Refractoriness: ≥ 1750°C

AZS refractory mortar is specifically designed for the construction of high-temperature industrial furnaces utilizing electrically fused AZS bricks. It serves as an essential material for building high-quality refractory structures, primarily applied in the following scenarios:

1. Glass melting furnace areas in contact with molten glass: Masonry of AZS bricks in critical locations such as tank walls, tank bottoms, flow channels, charging ports, and around bubblers.

2. Glass feed channel systems: Masonry of all AZS brick structures including channel base plates, side walls, and roof covers.

3. Specialty glass melting furnaces: AZS brick masonry for furnaces producing electronic glass, optical glass, pharmaceutical glass, etc.

4. AZS brick maintenance and repair: Used for patching and grouting localized damage in existing AZS brickwork.

5. Other high-temperature equipment utilizing AZS bricks: Such as specialized furnaces in certain chemical or metallurgical fields.
