Product description
High-strength and wear-resistant high temp castable refractory cement are mainly made of high-strength refractory raw materials such as special-grade alumina, corundum and silicon carbide as aggregates and fine powder, and added with micro powder. The material has the characteristics of good volume stability, high strength, good wear resistance, thermal shock resistance, corrosion resistance, no cracking, no peeling, etc. The product is mainly used in parts of industrial kilns with severe erosion and wear such as ball rotary kilns and coal injection pipes.
Advantages of high temp castable refractory cement:
◆ Environment friendly
◆ Reasonable raw material and size to make sure good fluidity
◆ High strength and high refractoriness
