RBSiC silicon carbide ceramic lining tube with high wear-resistance
RBSiC silicon carbide ceramic lining tube with high wear-resistance
also called silicon carbide wear resistance bushing,it is synthesized from silicon carbide and carbon at high temperature,belongs to a kind of silicon carbide product.The silicon carbide wear resistance parts are widely used in mining,ore crushing,screening and transport of high wear,high corrosive fluids,also very suitable for mechanical products with high precision and sealing requirements,such as high pressure pump,magnetic pump etc.Is a new type of wear resistance material.Reaction-sintering silicon carbide wear resistance bushing has the characteristics of high hardness,high wear resistance,impact resistance,high temperature resistance,acid and alkali corrosion resistance and so on,and the actual service life is more than 6 times that of polyurethane.It is especially suitable for the operation of classification, concentration and dehydration of strong abrasive and coarse-grained materials,has been successfully applied in many mines.Our company is a professional silicon carbide wear resistance ceramic products supplier,hardness second only to diamond,with high wear resistance,long service life features.The wear resistance pipe and elbow that produced with silicon carbide wear resistance lining,its ceramic lining thickness is 6-25mm,the structure is to install the already sintered ceramic tube into the corresponding caliber steel tube, with the glue in the middle.Wear resistance ceramic pipes have the following properties compared with the previous adopted cast-stone pipes,wear-resistant alloy cast steel pipes and ceramic composite pipes.
Features of sic ceramic bushing silicon carbide lining with high anti-wear property:
1.Liner engineering ceramics with high strength,high hardness,excellent wear and corrosion resistance.
2.Various processes:bonding,inlaying and socketing.
3.The ceramic is firmly bonded to the substrate and has good temperature resistance(-50℃ to 1350℃).
4.The surface of silicon carbide ceramic is smooth,it can prevent scale and dust.
5.High cost effective,simple process.
6.Easy to install.
