Alumina Lining Bricks
Alumina lining bricks are manufactured from high-grade alumina raw materials through strict proportioning, high-pressure pressing and high-temperature firing. With high Al₂O₃ content, uniform structure and stable performance, they are widely used as lining materials in high-temperature, high-wear and corrosive industrial environments.
Our alumina lining bricks provide excellent protection for industrial furnaces, kilns, pipelines, cyclones, chutes and reaction equipment, effectively reducing wear, corrosion and heat loss, and significantly improving equipment service life and production efficiency.
We support custom dimensions, special shapes and different alumina grades to meet your specific project requirements.
Key Advantages:
1. High Temperature Resistance
Can withstand long-term working temperature up to 1350°C–1750°C, depending on grade.
2. Extreme Wear Resistance
High hardness and low abrasion rate effectively resist material scouring and friction.
3. Strong Corrosion Resistance
Good resistance to acid, alkali, molten slag, dust and chemical corrosion.
4. Good Thermal Stability
Low thermal expansion rate, strong thermal shock resistance, less cracking.
5. Long Service Life
Reduce maintenance frequency, lower downtime and overall operation cost.
6. Easy Installation
Standard and custom sizes available for convenient construction and replacement.
