Advantages

1. High Temperature Resistance
High alumina bricks offer excellent thermal stability and can withstand temperatures up to 1750°C, maintaining reliable performance in high-temperature environments.

2. High Bulk Density
The dense structure provides high mechanical strength, strong load-bearing capacity, and good wear resistance.

3. Low Iron Content
Low iron impurities improve refractoriness and stability, preventing unwanted reactions at high temperatures.

4. Good Erosion Resistance
Excellent resistance to chemical erosion and slag corrosion, ensuring longer service life in harsh industrial conditions.

Key Features

  • Excellent resistance to high temperatures

  • High bulk density for enhanced durability

  • Low iron content for improved refractoriness

  • Strong resistance to erosion and chemical attack

Applications

  • Steelmaking furnaces

  • Ironmaking furnaces

  • Glass kilns

  • Ceramic tunnel kilns

  • Cement kilns
