High Alumina Brick SK Series

High Alumina Brick SK Series are neutral refractory materials mainly composed of high - purity alumina (Al₂O₃). They are made from high - alumina bauxite clinker as the main raw material through high - temperature sintering, and are ideal lining materials for high - temperature equipment in industries such as metallurgy, building materials, and chemicals.

Common Specifications: Standard brick size is 230mm×115mm×65mm. Special - shaped bricks can be customized.

Features and Properties

1. High - temperature Performance: The refractoriness reaches 1790 °C, with excellent high - temperature structural strength.
2. Thermal Stability: Capable of withstanding rapid heating and cooling conditions, with outstanding thermal - shock resistance.
3. Erosion Resistance: Resistant to both acidic and alkaline molten slag (better resistance to acid than to alkali).
4. Mechanical Strength: Compressive strength at normal temperature is ≥ 45 MPa, and it has good high - temperature wear resistance.
5. Shape Adaptability: Standard and special - shaped bricks are provided to meet the masonry requirements of complex structures.
