Brief: Discover the High Temperature Wear Resistance 95% Al2O3 Refractory White Corundum Brick, designed for electric arc furnaces. This corundum brick offers exceptional hardness, corrosion resistance, and high-temperature stability, making it ideal for demanding industrial applications.
Related Product Features:
  • High hardness with Mohs hardness close to 9, making it harder than steel.
  • Excellent corrosion resistance to acids, alkalis, and chemical solutions.
  • High temperature resistance with a load softening degree between 1600-1800°C.
  • Dimensional stability with good thermal shock resistance and refractoriness not lower than 1690°C.
  • High normal temperature compressive strength, reaching up to 340MPa.
  • Strong resistance to acidic or alkaline slag, metal, and glass liquid.
  • Available in two types: sintered corundum bricks and fused corundum bricks.
  • Widely used in blast furnaces, refining furnaces, glass melting furnaces, and petrochemical industrial furnaces.
Faqs:
  • What is the Al2O3 content in the corundum brick?
    The Al2O3 content in the corundum brick is greater than 90%, ensuring high performance in high-temperature environments.
  • What are the typical applications of this corundum brick?
    This corundum brick is used in iron-making blast furnaces, blast furnace hot blast stoves, refining furnaces, sliding water heaters, glass melting furnaces, and petrochemical industrial furnaces.
  • How does the corundum brick perform in thermal shock conditions?
    The corundum brick has good thermal shock resistance, with a linear expansion coefficient of about 0.03mm/degree between 20-450°C, allowing it to withstand high-temperature melt flow static pressure without rupture.
