Corundum Mullite Bricks are high-performance refractory material that combines the excellent properties of corundum (Al₂O₃) and mullite (3Al₂O₃·2SiO₂). It features high refractoriness, excellent thermal shock resistance, high load softening temperature, and strong resistance to erosion. It is widely used in industries such as steel, glass, ceramics, cement, petrochemicals, non-ferrous metals, and power generation. · High Refractoriness: With a refractoriness exceeding 1750°C, it is suitable for high-temperature environments. · Excellent Thermal Shock Resistance: Capable of withstanding rapid temperature changes, minimizing thermal shock damage. · High Load Softening Temperature: Maintains structural strength under high temperatures. · Strong Erosion Resistance: Demonstrates robust resistance to acidic, alkaline slags, and molten metals. · Low Creep: Minimal deformation under high temperature and load, ensuring a long service life.
