Chrome Corundum Brick

  • Using a-Al2O3 as raw material, adding appropriate amount of chromium oxide powder, chrome corundum powder and additives, etc., after molding, it is fired at a high temperature of 1700 ℃ to form chrome corundum bricks.
  • Advantages:

    excellent thermal shock stability, small high temperature creep value, and good corrosion resistance.
  • Application:

    It can be used as lining of glass melting furnace, small furnace and target wall of regenerator, brushed glass flow hole cover brick, E glass fiber kiln flue and rising part, ladle ventilation brick and heating furnace track in metallurgical industry and other parts.
