High-alumina brick

High-alumina bricks are manufactured using premium high-alumina bauxite clinker as the primary raw material, supplemented with binders, and processed through high-pressure forming and high-temperature firing. Their performance improves with increasing Al₂O₃ content, featuring:

High refractoriness: High Al₂O₃ content typically achieves refractoriness exceeding 1750°C

Excellent thermal shock resistance: Superior resistance to rapid thermal cycling compared to ordinary clay bricks

Outstanding chemical erosion resistance: Resists both acidic and alkaline furnace slags

High structural strength: Maintains good mechanical strength at both high and ambient temperatures

Superior high-temperature volume stability: Low linear change rate upon re-firing ensures long-term structural integrity of kilns

Key Technical Specifications (by grade):

High-alumina bricks, with their balanced performance and cost advantages, are suitable for high-temperature equipment across numerous industrial sectors:

1. Metallurgical Industry: Lining for blast furnaces, hot blast stoves, torpedo ladles, steel ladles, heating furnaces, and soaking furnaces.

2. Building Materials Industry: Preheating zones, calcination zones, coolers in cement rotary kilns, and regenerators in glass melting furnaces.

3. Ceramics Industry: Kiln bodies and kiln car platforms for tunnel kilns, shuttle kilns, and roller kilns.

4. Chemical Industry: High-temperature reaction equipment such as gasifiers, converters, and cracking furnaces.

5. Power Industry: Anti-wear linings for circulating fluidized bed boilers.

6. Other Industries: Waste incinerators, lime kilns, and various heat treatment furnaces.
