1.Introduction of silicon carbide :
Silicon carbide is an inorganic non-metallic materials with high hardness, high wear resistance, low coefficient of friction, oxidation resistance, good thermal stability, low thermal expansion coefficient, thermal conductivity and thermal shock and great resistance to chemical corrosion, etc. excellent characteristics, can be used for a variety of requirements for abrasion, corrosion and high temperature mechanical equipment. Engineering and technical staff after years of unremitting efforts, has greatly improved the performance of silicon carbide. Now, silicon carbide has become an important engineering materials. Widely used in the field of machinery, metallurgy, petrochemical, shipbuilding, military equipment, etc., such as mechanical seal friction, plain bearings, nozzles, cutting tools, etc.
2.Features of silicon carbide ring :
1) Heat shock stablity
2) chemical corrosion-resistant( resistant to strong acid/strong alkali /salt / gas / deleterious )
3) High temper-endure(up to 1650°)
4) Wearing/corrosion/oxidation resistant
5) Highly performance of mechanical strength
6) Cleaning or etching the hardest sub-surfaces
7) long life high hardness resistant to wear; especially resistant to hydrofluoric acid
8) Used for grinding, lapping, and wire saw cutting as well as abrasive blasting

4.Applications of silicon carbide thrust ring :
With silicon carbide ceramics the material properties remain constant up to temperatures above 1,400°C. The high Young’s modulus > 400 GPa ensures excellent dimensional stability. These material properties make silicon carbide predestined for use as a construction material. Silicon carbide masters corrosion, abrasion and erosion as skillfully as it stands up to frictional wear. Components are used in chemical plants, mills, expanders and extruders or as nozzles, for example.
“The variants SSiC (sintered silicon carbide) and SiSiC (silicon infiltrated silicon carbide) have established themselves. The latter is particularly suitable for the production of complex large-volume components.”
Silicon carbide is toxicologically safe and can be used in the food industry. Another typical application for silicon carbide components is dynamic sealing technology using friction bearings and mechanical seals, for instance in pumps and drive systems. Compared to metals, silicon carbide enables highly economical solutions with longer tool life when used with aggressive, high-temperature media. Silicon carbide ceramics are also ideal for use in demanding conditions in ballistics, chemical production, energy technology, paper manufacturing and as pipe system components.
5.production lines:
Granulation-compression moulding-sintering-grinding -finishing and fining the inspection for each step of the production is conducted strictly.
