High Alumina Bricks
High alumina bricks from Zhengzhou Huachen Refractory Co., Ltd. are calcined refractory products with an Al2O3 content exceeding 55%, engineered for extreme heat resistance in industrial furnaces and kilns. The bricks are formed from high-grade bauxite or silica-alumina raw materials, achieving a refractoriness of 1750 - 1790°C, with a load softening temperature higher than clay bricks but lower than silica bricks due to the lack of a fully formed mullite crystal network. Their neutral refractory profile resists both acid and alkali slag, though alkali resistance is slightly reduced by the presence of SiO2.
The material’s composition typically includes calcined bauxite as the primary aggregate, with controlled impurities to minimise glass phase formation, ensuring stability under thermal cycling. Standard industry grades for high alumina bricks often classify products by Al2O3 content, such as 55%, 60%, 70%, or 80%, with higher percentages offering greater thermal and mechanical performance. These bricks are commonly supplied in standard dimensions for industrial linings, with tight tolerances to ensure uniform masonry.
Industries such as steelmaking, cement production, glass manufacturing, and petrochemical processing rely on these bricks for lining electric arc furnaces, rotary kilns, and glass furnaces. Buyers typically source them in bulk, with packaging on wooden pallets for secure export. Confirmation of exact dimensions, Al2O3 grade, and application-specific suitability is recommended before ordering, as performance varies with composition and firing conditions.

Sourcing High Alumina Bricks from Zhengzhou Huachen Refractory Co., Ltd. - China Import Guide
Before ordering high alumina bricks from Zhengzhou Huachen Refractory Co., Ltd., verify the exact Al2O3 content and grade to ensure compatibility with your application. Confirm the bricks’ dimensions and tolerances, as these must align with your furnace or kiln design for proper installation. Request documentation on thermal properties, such as refractoriness and load softening temperature, to validate performance claims.
Discuss logistics details, including lead time, Incoterms, and packaging requirements. High alumina bricks are typically shipped on wooden pallets, but confirm the supplier’s packaging standards to avoid damage during transit. Clarify whether the supplier can accommodate specific Incoterms, such as FOB or CIF, and negotiate payment terms that align with your procurement policies.
Conduct quality checks upon receipt, including visual inspection for cracks or defects and verification of dimensions against your specifications. Request test certificates or third-party inspections if your industry requires validation of thermal properties. Ensure all documentation, including material safety data sheets and compliance certificates, is provided to meet regulatory and operational standards.
