Application Temperature 1500 Celsius High Alumina Refractory Bricks Customized Bulk Density 3.3 to 3.8 g cm3 Industrial

Product Description:

The High Alumina Refractory Bricks are engineered to meet the demanding requirements of high-temperature industrial applications. These bricks are specially designed to withstand extreme conditions, making them an ideal choice for furnaces, kilns, and other thermal processing equipment operating at temperatures of 1500℃ and above. With an application temperature of ≥1500℃, these bricks provide exceptional durability and stability in environments where ordinary refractory materials would fail.

One of the standout features of these High Alumina Refractory Bricks is their impressive bulk density, which ranges between 3.3 and 3.8 g/cm³. This high bulk density contributes to the brick’s structural integrity, enhancing its resistance to mechanical wear and abrasion during operation. The substantial density also aids in maintaining the brick's shape and strength under heavy loads and thermal cycling, ensuring a long service life and reliable performance in harsh conditions.

These bricks boast a high refractoriness under load (RUL) of ≥1700℃, indicating their capability to retain strength and resist deformation at elevated temperatures. This property is crucial for maintaining furnace linings and other high-temperature installations where material stability under load is essential for safe and efficient operation. Alongside their refractoriness, the High Alumina Refractory Bricks exhibit excellent cold crushing strength of ≥120 MPa, providing outstanding resistance to mechanical stresses and impacts during installation and service.

Thermal performance is another critical aspect of these bricks. They feature low thermal conductivity, which minimizes heat loss and improves energy efficiency in thermal processes. This characteristic not only helps in reducing operational costs by conserving heat but also protects the furnace structure from thermal damage. Furthermore, the bricks demonstrate good thermal shock resistance, allowing them to withstand rapid temperature changes without cracking or spalling. This makes them particularly suitable for applications involving frequent heating and cooling cycles.

The High Alumina Refractory Bricks are an excellent choice for industries requiring durable and reliable refractory materials, including steelmaking, glass production, cement manufacturing, and petrochemical processing. Their composition often includes Alumina-Chrome-Zr brick technology, which enhances their overall performance by combining the benefits of alumina, chromia, and zirconia. This combination results in superior resistance to chemical attack, abrasion, and thermal degradation, making Alumina-Chrome-Zr brick a preferred material in many high-temperature applications.

Incorporating Alumina-Chrome-Zr brick components into the High Alumina Refractory Bricks ensures enhanced durability and longevity. The presence of chrome improves the material’s resistance to slag corrosion, while zirconia contributes to excellent thermal shock resistance and mechanical strength. This synergy of materials in Alumina-Chrome-Zr brick formulations creates a refractory product that consistently meets the rigorous demands of modern industrial processes.

Overall, High Alumina Refractory Bricks with Alumina-Chrome-Zr brick technology represent a superior solution for high-temperature refractory applications. Their combination of high refractoriness, substantial bulk density, strong mechanical properties, and excellent thermal performance makes them indispensable in maintaining the efficiency and safety of industrial furnaces and kilns. Choosing these bricks means investing in quality, durability, and performance that will stand the test of time in the most challenging thermal environments.
