High alumina bricks are type of refractory material primarily composed of aluminum oxide (Al₂O₃). They are characterized by high refractoriness, excellent erosion resistance, and a high load softening temperature. They are widely used in industries such as steel, glass, ceramics, and cement. ·High Refractoriness: With a refractoriness exceeding 1700°C, it is suitable for high-temperature environments. ·Excellent Erosion Resistance: It exhibits strong resistance to both acidic and alkaline slags. ·High Load Softening Temperature: It maintains good structural strength under high temperatures.
Steel Industry: Used for lining, roof, and bottom of steelmaking furnaces and hot blast stoves.
Ceramics Industry: Applied in the firing zone, saggars, and kiln furniture of ceramic kilns.
Cement Industry: Employed in the firing zone, transition zone, and cooling zone of cement rotary kilns.
