    Fused white corundum

    Exothermic-insulating sleeves are used to increase the yield in foundry practice. Function of the sleeve is predominant to enhance the effective casting modulus by increasing feeding efficiency. This is represented by a modulus extension factor (MEF)

    product details
    • Fused white corundum is a kind of high-grade and middle level refractory material, with the host lattice of ɑ-AL2O3, and in white and crystal-like color. The products are of high bulk density and low air hole rate, which can efficiently improve dimensional stability and thermal shock resistance of materials.

      Fused white corundum is a primary material for production of high-grade and middle level unshaped and shaped refectory.such as large ladle castable, high-grade iron runner castable coating materials. precast parts. various kinds of corundum products, such as corundum brick. corundum sagger and corundum mullite sagger, corundum porous plug brick for refining.overall spray gun, composite water gap. high temperature industrial furnace lining, etc. It is widely used in steel, cement ceramics, abrasive, petrochemical, and other industries.
