Cold Crushing Strength≥120MPa Alumina Chrome Zr Brick Bulk Density 3.3 to 3

Product Description:

The High Alumina Refractory Bricks are engineered to deliver exceptional performance in high-temperature industrial applications. These bricks are specifically designed using high-quality raw materials, including chrome, to ensure superior durability and resistance to thermal shock. The incorporation of chrome enhances the brick’s ability to withstand extreme environments, making it an ideal choice for demanding refractory linings.

One of the standout features of these bricks is their robust bulk density, which ranges between 3.3 to 3.8 g/cm³. This optimal density contributes to the brick's strength and longevity, providing a solid structure that can endure heavy mechanical stress and high temperatures typical in furnaces, kilns, and other high-heat environments. The bulk density is carefully controlled to balance weight and strength, ensuring that the bricks maintain their integrity over prolonged usage.

Crafted with an impressive cold crushing strength of ≥120 MPa, these High Alumina Refractory Bricks exhibit remarkable resistance to compressive forces. This high crushing strength is crucial for applications where the bricks are subjected to heavy loads and aggressive mechanical wear. It ensures that the bricks remain intact and reliable, reducing maintenance needs and downtime in industrial operations.

The chemical composition of these bricks is meticulously formulated to include key components such as Al2O3 (alumina), SiO2 (silica), Fe2O3 (iron oxide), CaO (calcium oxide), and MgO (magnesium oxide). The high alumina content contributes significantly to the brick’s excellent resistance to corrosion and abrasion. Silica and iron oxide provide additional structural stability, while calcium oxide and magnesium oxide improve the overall refractory performance by enhancing slag resistance and thermal stability.

Customization is a notable advantage of these High Alumina Refractory Bricks. They are available in various sizes tailored to meet specific project requirements, allowing for precise fitting and optimal installation efficiency. This flexibility ensures that the bricks can be used in diverse applications, from lining blast furnaces and steel ladles to cement kilns and petrochemical reactors.

Among the range of refractory products, the Alumina-Chrome-Zr brick stands out for its exceptional combination of alumina, chrome, and zirconia. This composite structure provides enhanced resistance to chemical attack, thermal shock, and high-temperature erosion. The Alumina-Chrome-Zr brick is particularly favored in environments where exposure to molten metals and corrosive slags is frequent, as it maintains structural integrity and performance under such harsh conditions.

In summary, the High Alumina Refractory Bricks represent a superior choice for industries requiring reliable, durable, and high-performance refractory materials. Their carefully balanced bulk density, impressive cold crushing strength, and optimized chemical composition make them suitable for a wide range of high-temperature applications. With the added benefit of customizable sizes and the proven advantages of the Alumina-Chrome-Zr brick technology, these bricks ensure enhanced operational efficiency and longevity in refractory linings.

Applications:

The Annec High Alumina Refractory Bricks, originating from China, are specially designed to withstand extreme temperatures and harsh industrial environments. With an application temperature of ≥1500℃ and a working temperature range between 1300-1560℃, these bricks are ideal for high-temperature applications where durability and thermal stability are paramount. The chemical composition, including Al2O3, SiO2, Fe2O3, CaO, and MgO, ensures excellent resistance to thermal shock, corrosion, and abrasion, making them highly reliable in demanding conditions.

One of the primary application occasions for Annec’s Alumina-Chrome-Zr brick is in the steelmaking industry. These bricks are frequently used to line blast furnaces, converters, and electric arc furnaces, where high temperatures and aggressive slag environments prevail. The high alumina content combined with chrome and zirconium additives enhances the brick’s ability to resist slag corrosion, extending the lifespan of furnace linings and reducing maintenance costs. This makes the Alumina-Chrome-Zr brick a preferred choice for steel plants aiming to improve operational efficiency and safety.

Another significant scenario for these high alumina refractory bricks is in cement rotary kilns. Operating under high thermal stress and chemical attack from alkaline materials, the bricks provide excellent structural support and heat insulation. Their ability to maintain integrity at temperatures up to ≥1700℃ (RUL) ensures that the kiln lining remains stable over long operational periods, minimizing downtime and improving productivity.

Annec’s Alumina-Chrome-Zr brick is also widely used in petrochemical cracking furnaces, glass melting furnaces, and non-ferrous metal smelting furnaces. In these applications, the bricks' high alumina content combined with chrome and zirconium enhances resistance to alkali and acidic slags, thermal shock, and mechanical wear. This makes them indispensable in industries requiring refractory materials that deliver consistent performance under extreme thermal and chemical conditions.

In summary, the Annec High Alumina Refractory Bricks, with their robust chemical composition and high-temperature endurance, are perfectly suited for heavy industrial use. Whether it is steelmaking, cement production, glass manufacturing, or petrochemical processing, the Alumina-Chrome-Zr brick provides reliable, long-lasting protection and performance in some of the most challenging environments.
