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.

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.
Silicon carbide ceramics have the best oxidation resistance among carbides, but between 1000-1400°C, the oxidation rate of SiC in the air is higher. The volume resistivity of silicon carbide does not change much in the range of 1000-1500°C. With their good chemical stability, high mechanical strength, and thermal shock resistance. Silicon carbide plate is widely used in various industrial fields, petroleum, laser, and heat treatment industries.
“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
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.
