Xintai Corundum Refractory Castables are designed to offer exceptional performance in high-temperature environments. Made from a blend of high-purity corundum, bauxite clinker, and advanced calcium aluminate cement, our corundum castables are highly resistant to heat, wear, and thermal shock. These high-strength, durable castables can withstand extreme temperatures from 1400°C to 1650°C, making them perfect for a wide range of industrial applications.

Our corundum castables are engineered using advanced micro-powder technology and are constructed through pouring methods for ease of use. They can be directly applied to the desired areas by mixing with water and stirring, followed by vibration application. Alternatively, prefabricated parts can be supplied for quicker and easier installation. With Xintai’s corundum refractory castables, you benefit from a highly effective solution for your high-temperature requirements.

Product Features

High Refractoriness: With Al₂O₃ content exceeding 90%, these castables exhibit outstanding resistance to high temperatures, making them ideal for use in high-temperature kilns and furnaces.
High Bulk Density: The high bulk density enhances the structural integrity of the castable, making it resistant to wear and erosion in the harshest environments.
Flexural Strength: Offers excellent mechanical strength, ensuring stability and longevity in applications exposed to fluctuating temperatures.
Easy Construction: Our corundum castables can be easily applied by mixing with water and then using vibration or manual ramming methods for smooth and durable surfaces.
Long Service Life: The castables are resistant to both mechanical wear and chemical corrosion, significantly extending the lifespan of your kilns and furnaces.

Applications

Xintai Corundum Refractory Castables are highly versatile and can be used in a range of industrial applications, particularly those requiring high thermal resistance and durability.

Cement Rotary Kilns: Protects against slag erosion and high-temperature damage in the kiln. Commonly used in areas such as grate coolers, tertiary air ducts, and hoods.
Circulating Fluidized Bed (CFB): Ideal for furnace linings, cyclone separators, and feeders in gasification, combustion, and desulfurization processes.
Other High-Temperature Kilns: Perfect for use in furnaces, incinerators, and other high-temperature processing systems.

The superior performance of Xintai Corundum Refractory Castables improves the service life of kilns by 10% to 15%, making them an excellent choice for industrial applications demanding reliability and durability.
