Corundum Mullite Castable Introduction

Corundum mullite refractory castable is a kind of refractory castable which contains Al2O3 more than 70%. It is made from corundum, mullite, dispersant and coagulant according to a certain proportion. Corundum mullite brick features with high temperature strength, wear resistance, high thermal conductivity, good thermal shock resistance and air tightness. In addition, it cures fast with high strength at the early stage. Corundum mullite castable is widely used in circulating fluidized bed boiler, metallurgy, oil chemical, thermal power, and other industries.
