High alumina insulation bricks for industrial furnace linings High temperature resistant lightweight insulation bricks High refractoriness mullite bricks suitable for ceramic roller kilns Metallurgical heating furnaces

This high-alumina insulating brick is crafted from high-quality industrial alumina and high-alumina bauxite, with an alumina content of ≥48%. Its primary crystal phase is mullite or corundum + glass. It offers a maximum refractory temperature of 1800°C and a long-term operating temperature of 1650°C. Its excellent thermal shock resistance, high strength, and low thermal conductivity significantly reduce the heat capacity of furnaces, saving energy and extending furnace life. Its porous structure balances thermal insulation performance with mechanical stability, meeting international refractory standards (such as ISO and ASTM). It is widely used in high-temperature equipment in the steel, ceramics, petrochemical, and other industries worldwide. We specialize in the manufacture of high-quality industrial refractory materials, with exports to Europe, America, Southeast Asia, the Middle East, and other regions, providing a trusted, export-grade refractory solution.

1. High-purity raw materials ensure stable performance and refractoriness up to 1800°C;
2. Low thermal conductivity design, significant energy saving effect, and improved furnace temperature control accuracy;
3. Excellent thermal shock resistance and compression strength, suitable for frequent start-stop conditions;
4. Standardized production process, good batch consistency, suitable for large-scale procurement;
5. Lightweight structure reduces the load on the furnace and facilitates installation and maintenance.

Suitable for lining insulation of high-temperature industrial equipment such as hot blast furnaces, ceramic roller kilns, steelmaking heating furnaces, petrochemical reforming furnaces, and glass melting furnaces in the metallurgical industry. This product is primarily targeted at customers in the global building materials, metallurgy, chemical, and energy sectors, and is particularly suitable for industrial users seeking energy conservation, consumption reduction, and equipment longevity.
