Andalusite bricks are type of refractory material primarily composed of andalusite (Al₂SiO₅). It features high refractoriness, excellent thermal shock resistance, and strong erosion resistance. It is widely used in industries such as ceramics, glass, and cement. · High Refractoriness: With a refractoriness of over 1700°C, it is suitable for high-temperature environments. · Excellent Thermal Shock Resistance: Capable of withstanding rapid temperature changes, reducing thermal shock damage. · Strong Erosion Resistance: Highly resistant to both acidic and alkaline slags. · Low Creep: Minimal deformation under high temperature and load, ensuring a long service life.
Ceramics Industry: Used in the firing zone of ceramic kilns, saggars, and kiln furniture.
Glass Industry: Applied in the melting tank, refining tank, and forehearth of glass furnaces.
Cement Industry: Utilized in the burning zone, transition zone, and cooling zone of cement rotary kilns.
