Product Description

  Product Overview:

     Tabular corundum casting material uses high-purity, high-melting plate-shaped corundum as the main raw material, combined with high-quality active alumina powder and other raw materials, has high thermal shock stability, anti-peeling and creep resistance. High fire resistance, good volume stability, high temperature performance and wear resistance are significantly enhanced. At the same time, by adding silicon carbide, the corrosion resistance of Corundum texture casting material is greatly enhanced. Mainly suitable for large and medium-sized cement kiln mouths and coal injection pipes.
