    Refractory Grade Calcined Bauxite Aggregate For Industrial Applications

    Product Description of Supply High-Quality Refractory Grade Calcined Bauxite Bauxite Aggregate for Industrial Applications
    Bauxite, also known as alumina, is primarily composed of alumina and hydrated alumina, along with various impurities. This earthy mineral can appear in shades of white, gray, brown, yellow, or light red, depending on its iron content. With a density ranging from 3.9 to 4 g/cm³ and a hardness of 1-3, bauxite is quite brittle and challenging to melt. While it does not dissolve in water, it is soluble in sulfuric acid and sodium hydroxide solutions. Bauxite is predominantly utilized in the production of aluminum and refractory materials.
    As a top supplier of refractory grade calcined bauxite, Rongsheng Refractory provides a wide range of bauxite products, including refractory grade bauxite, calcined bauxite aggregate, and bauxite powder, all offered at competitive prices.
    Features of Calcined Bauxite
    High Alumina Content: Typically contains over 48% Al2O3, making it suitable for high-temperature applications.
    Excellent Refractoriness: Can withstand temperatures up to 1780°C, making it ideal for refractory materials.
    Low Iron Content: Low Fe2O3 levels enhance its purity, making it a stable choice for demanding industrial uses.
    High Density and Hardness: Calcined bauxite is durable, resistant to abrasion, and ideal for products needing strength and longevity.
    Thermal Stability: Retains stability under extreme heat, making it reliable for applications in steel, ceramics, and aluminum production.
    Chemical Resistance: Resists corrosion from acidic and alkaline environments, ensuring longevity in chemical applications.

    Applications of Calcined Bauxite and Bauxite Powder

    1. Aluminum Production: Crucial for the extraction and production of aluminum metal.

    2. Precision and Investment Casting: Bauxite fines can be utilized to create molds for high-accuracy casting processes.

    3. Refractory Materials: High alumina bauxite offers excellent refractoriness, reaching temperatures of up to 1780°C, and demonstrates outstanding chemical stability and mechanical strength (Al2O3 ≥ 48% with low Fe2O3 content).

    4. Aluminosilicate Refractory Fiber: When high alumina bauxite grog is subjected to temperatures of 2000°C-2200°C in an electric arc furnace, it melts to form aluminosilicate refractory fiber, which can be processed into blankets, boards, and textiles.

    5. Lining for Steel Ladles: The combination of magnesia and bauxite grog with binders enhances the performance of linings in molten steel ladles.

    6. Bauxite Cement Production: Serves as a primary component in the formulation of bauxite cement.

    7. Abrasive Manufacturing: Plays a significant role in the production of abrasive materials.

    8. Ceramics Production: Utilized in the manufacture of a wide variety of ceramic goods.

    9. Chemical Manufacturing: Employed in the synthesis of various aluminum compounds.
