Cold Crushing Strength≥120MPa Alumina Chrome Zr Brick Suitable for Working Temp 1300 1560 Industrial Heat Resistant Bricks

Product Description:

High Alumina Refractory Bricks, specifically the SK-36 type, represent a premium class of refractory materials designed to withstand extremely high temperatures and harsh industrial environments. These bricks are engineered to perform reliably in applications where conventional refractory materials would fail, making them indispensable in modern high-temperature industrial furnaces, kilns, and other thermal processing equipment. With an impressive application temperature of ≥1500℃ and a Refractoriness Under Load (RUL) of ≥1700℃, these bricks ensure durability and stability under severe operating conditions.

The key to the exceptional performance of these High Alumina Refractory Bricks lies in their unique composition, which prominently features alumina, chrome, and zircon components. Often referred to as Alumina-Chrome-Zr bricks, these materials combine the benefits of high alumina content with the enhanced chemical resistance and structural integrity provided by chrome and zircon additives. This combination results in a refractory brick that not only withstands thermal shock and mechanical stress but also resists corrosion and wear caused by molten slags and aggressive gases.

In industrial settings such as steelmaking, cement production, glass manufacturing, and non-ferrous metal processing, the demands on refractory materials are immense. The Alumina-Chrome-Zr brick meets these demands by offering superior thermal stability and mechanical strength at elevated temperatures. The SK-36 type bricks are specifically formulated to maintain their integrity and performance at temperatures exceeding 1500℃, making them ideal for lining high-temperature industrial furnaces and kilns where consistent thermal efficiency and longevity are critical.

One of the standout features of the Alumina-Chrome-Zr brick is its excellent resistance to slag corrosion. The presence of chrome enhances the brick’s ability to resist chemical attack from molten slags, which are common in metallurgical processes. Zircon, on the other hand, contributes to improved thermal shock resistance and reduces the risk of cracking and spalling during rapid temperature changes. This makes these bricks highly reliable in dynamic operating environments where temperature fluctuations are frequent.

Moreover, the high alumina content in these bricks ensures a high melting point and excellent refractory properties, which are essential for maintaining furnace efficiency and reducing maintenance downtime. The combination of alumina, chrome, and zircon also imparts a dense and stable microstructure, minimizing porosity and thereby enhancing the brick’s resistance to penetration by molten materials and gases.

Installation of SK-36 Alumina-Chrome-Zr bricks in industrial furnaces and kilns leads to improved operational performance and longer service life of refractory linings. Their robust mechanical properties allow them to withstand substantial loads without deformation, which is reflected in their high Refractoriness Under Load (RUL) rating of ≥1700℃. This ensures that the bricks maintain dimensional stability even under mechanical stress at elevated temperatures, thereby reducing the risk of structural failure.

In summary, High Alumina Refractory Bricks of the SK-36 type, known as Alumina-Chrome-Zr bricks, offer an outstanding combination of high-temperature resistance, mechanical strength, and chemical durability. Their application temperature of ≥1500℃ and RUL of ≥1700℃ make them an excellent choice for lining high-temperature industrial furnaces, kilns, and related equipment. By incorporating high alumina, chrome, and zircon components, these bricks deliver superior performance in demanding industrial processes, ensuring both operational efficiency and extended refractory lifespan.

These SK-36 type bricks boast an impressive working temperature range of 1300 to 1560 degrees Celsius, making them ideal for applications requiring superior heat resistance and durability. With an alumina (Al2O3) content ranging from 75% to 85%, these bricks ensure excellent thermal stability and mechanical strength under extreme conditions.

One of the key application occasions for Annec High Alumina Refractory Bricks is in the lining of high temperature industrial furnaces used in steel, cement, glass, and metallurgical industries. Their robust chemical composition, including Al2O3, SiO2, Fe2O3, CaO, and MgO, allows them to withstand corrosive slags and thermal shocks, significantly extending the service life of furnace linings. These bricks are particularly suitable for environments where the operational temperatures fluctuate but remain within the 1300-1560°C range.

In ceramic and lime kilns, Annec’s High Alumina Refractory Bricks provide exceptional resistance to thermal cycling and chemical attack. Their high alumina content ensures that the bricks maintain structural integrity and resist deformation, improving kiln efficiency and reducing downtime for maintenance. The bricks’ stability also makes them suitable for use in power plants and incinerators, where consistent high-temperature operation is critical.

Additionally, the Annec High Alumina Refractory Bricks can be used as a reliable alternative to Alumina-Chrome-Zr brick in applications where high alumina content and thermal stability are paramount. While Alumina-Chrome-Zr bricks are known for their durability and resistance, Annec’s product offers comparable performance with optimized chemical composition tailored for diverse industrial scenarios. This makes Annec bricks a cost-effective and efficient choice for industries seeking to balance performance with economic considerations.

In summary, Annec High Alumina Refractory Bricks are perfectly suited for high temperature industrial furnaces, kilns, and other thermal equipment operating up to 1560°C. Their excellent chemical makeup and high alumina content provide superior resistance to heat, corrosion, and mechanical stress, making them an essential material in heavy industry. Whether replacing or complementing Alumina-Chrome-Zr brick, Annec bricks deliver reliability and long-lasting performance in demanding applications.
