Reaction-sintered silicon carbide wear-resistant pipe coat silicon carbide as the main raw material, adding a variety of chemical wear-resistant raw materials and anti-oxidants, effectively improve the wear resistance of products, SiO, micro powder to do high temperature combination phase, a silicon carbide product fired at high temperature. With high temperature dimensional stability, deformation resistance, high temperature strength; Thermal shock resistance, wear resistance, corrosion resistance; Resistance to oxidation and erosion. Can be widely used in: electric power, steel slag trench, coal chemical industry, mining, transportation pipeline.
