Magnesia-alumina spinel bricks are refractory material primarily composed of magnesia-alumina spinel (MgAl₂O₄). It features high refractoriness, excellent thermal shock resistance, and strong erosion resistance. It is widely used in industries such as steel, cement, and glass. · 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.
Steel Industry: Used in the lining, roof, and bottom of steelmaking furnaces and converters.
Cement Industry: Utilized in the burning zone, transition zone, and cooling zone of cement rotary kilns.
Glass Industry: Applied in glass furnaces.
