Dense fused 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
  • Dense fused corundum is a kind of top refractory material with the host lattice of ɑ-AL2O3 and in hoar color. The products are of high melting point, high bulk density and low air hole rate. It has fine fastness, slag resistance, dimensional stability and thermal shock resistance under high temperature. It is recognized as the most outstanding refractory in the corundum series.


    Dense fused corundum is an ideal material for making unshaped refractory materials such as blast furnace iron runner castable, ladle castable, ramming material, precast parts, etc and various shaped products such as continuous castings, gas supply brick and nozzle seat brick, etc. It is widely used in iron and steel.cement, ceramics and petrochemical, etc
