Product Description
High Alumina Bricks (70% Al₂O₃) are premium refractory bricks designed for high-temperature applications, offering superior resistance to thermal shocks, abrasion, and chemical corrosion. Manufactured using high-purity raw materials and advanced processing techniques, these bricks exhibit excellent mechanical strength and durability. Their low iron and high alumina content make them ideal for environments requiring superior heat resistance and minimal contamination.
Performance and characteristics of High Alumina Fire Brick:
- High Thermal Stability: Can withstand temperatures up to 1700°C, making them suitable for extreme heat environments.
- Excellent Chemical Resistance: High resistance to slag, acids, and alkalis ensures durability in chemical and metallurgical industries.
- Superior Mechanical Strength: High Cold Crushing Strength (CCS) and Modulus of Rupture (MOR) enhance the brick’s load-bearing capability.
- Low Porosity & High Bulk Density: Ensures reduced permeability and improved resistance to wear and corrosion.
- Minimal Linear Expansion: Reduces the risk of thermal cracking, ensuring long service life in kilns and furnaces.
