High Alumina Brick

1. Product Overview

High Alumina Brick is a premium refractory material manufactured with a high concentration of alumina (Al₂O₃) to provide exceptional resistance to heat, abrasion, chemical attack, and thermal shock. It is primarily used for lining high-temperature industrial furnaces, kilns, reactors, boilers, and other thermal-processing equipment. Its high refractoriness, mechanical strength, and dimensional stability support longer service life and reduced maintenance requirements. High Alumina Brick is a strategic refractory solution for industries requiring dependable performance under demanding operating temperatures and harsh processing conditions.

2. Key Specifications & Technical Characteristics

• Material Composition: High-purity alumina-based refractory material, typically produced from high-alumina bauxite, calcined alumina, or related alumina-rich raw materials.
• Alumina Content: Available in multiple grades, commonly ranging from approximately 55% to 90%+ Al₂O₃, depending on application requirements.
• Refractoriness: Excellent resistance to high-temperature operation, with grade-dependent service temperatures typically exceeding 1,500°C.
• Physical Form: Dense, rigid refractory bricks with uniform dimensions and engineered shapes available for specific furnace designs.
• Color: Typically light grey, cream, beige, or white, depending on raw materials and manufacturing process.
• Bulk Density: Generally approximately 2.3–3.0 g/cm³, depending on alumina grade and product specification.
• Cold Crushing Strength: High mechanical strength suitable for heavy-duty refractory lining applications.
• Thermal Properties: Low creep, good thermal stability, and strong resistance to thermal shock depending on grade and formulation.
• Chemical Resistance: Strong resistance to slags, molten materials, and aggressive industrial atmospheres.
• Customization: Standard and special shapes, dimensions, alumina grades, and technical specifications can be supplied according to project requirements.
• Packaging: Export-grade pallets, shrink wrapping, cartons, or customized industrial packaging.
• Shelf Life: Long-term storage is possible when kept dry, protected from moisture, and stored on suitable pallets.

3. Core Industrial Applications

• Steel & Metallurgy: Used in furnace linings, soaking pits, reheating furnaces, ladle areas, and other high-temperature zones exposed to severe heat and mechanical wear.
• Cement Industry: Applied in rotary kilns, preheaters, coolers, and high-temperature processing areas requiring durable refractory protection.
• Glass Manufacturing: Used in furnace linings and high-temperature zones where resistance to heat and chemical corrosion is essential.
• Non-Ferrous Metals: Suitable for furnaces and thermal equipment processing aluminium, copper, zinc, and other metals.
• Petrochemical & Chemical Processing: Used in reactors, reformers, incinerators, and other equipment exposed to elevated temperatures and corrosive environments.
• Power Generation: Applied in boilers, combustion chambers, and industrial thermal systems.
