Corundum bricks are high-performance refractory material primarily composed of corundum (Al₂O₃). It is characterized by high refractoriness, excellent thermal shock resistance, and strong resistance to erosion. It is widely used in industries such as steel, glass, ceramics, and cement. · High Refractoriness: With a refractoriness exceeding 1750°C, it is suitable for high-temperature environments. · Excellent Thermal Shock Resistance: It can withstand rapid temperature changes, minimizing thermal shock damage. · Strong Erosion Resistance: It exhibits robust resistance to acidic and alkaline slags, as well as molten metals.
Steel Industry: Used for lining, roof, and bottom of steelmaking furnaces and hot blast stoves.
Glass Industry: Utilized in the melting tank, refining tank, and forehearth of glass furnaces.
Ceramics Industry: Applied in the firing zone, saggars, and kiln furniture of ceramic kilns.
