Graphite products and process are widely used in many different fields, such as machinery, electron, semiconductor, mono-crystal silicon metallurgy, oil, chemistry,conductive material etc.we constantly maintain our research and development in the carbon and graphite technology.We interested in supplying those materials for you.As a leading Chinese graphite manufacturer and supplier, we specialize in providing high quality graphite material, carbon carbon composites and graphite parts.The below are different types of graphite applications.
1.As refractory materials including refractory brick, crucible curse, continuous casting powder, casting mold, mold detergent and high temperature resistant material.
Magnesia carbon brick, magnesia carbon refractories is in the mid 1960s, by the United States developed; in the world within the scope of magnesia carbon brick has been widely used in steelmaking, and has become a graphite a traditional uses. Alumina carbon brick, aluminum carbon refractory material mainly used in continuous casting, steel billet from a transmission pipeline protective cover, water nozzle and oil pipe bomb.
Forming and refractory made of graphite crucible and related products, such as crucible, retort, plug head and nozzle, with high fire resistance, low thermal expansion, metal smelting process by metal infiltration and erosion is also stable, high temperature and good thermal shock resistance and excellent thermal conductivity, so increasing graphite disaster and related products is widely used in process for the direct melt metal.
2.Steelmaking
Graphite and other impurities can be used as the material for the steel industry carburetant. Using carburizing carbonaceous material, is very wide, including artificial graphite, petroleum coke, metallurgical coke and natural graphite. In the world of one of the main uses of steel carbon graphite or amorphous graphite.
3.As conductive material
Graphite in the electrical industry are widely used as electrode, brush, carbon, carbon nanotubes, mercury rectifier anode, graphite gaskets, telephone parts, TV picture tube coating and so on. Among them, the graphite electrode is widely used in the smelting of various alloy steels, iron alloys, graphite electrodes. The graphite used in the electrical industry is very high in granularity and grade..
4.For wear and lubrication materials
Graphite often lubricant in mechanical industry. Lubricating oil often cannot in high speed, high temperature and high pressure conditions using, and abrasive resistant graphite materials can in a 2000 DEG C temperature of 200 DEG C and at high sliding speed (100 m / s) without the lubricating oil. Many equipment for conveying corrosive medium, the widespread adoption of graphite material piston ring, sealing ring and the bearing, they are running, do not need to add lubricating oil, graphite and metal processing (Roberts, trombone) good lubricant.
5.As corrosion-resistant materials
Graphite has good chemical stability.. After special processing of graphite, corrosion resistance, good thermal conductivity, low permeability characteristics, widely used in the manufacturing of heat exchanger, reaction tank, condenser, burning tower, absorption tower, cooler, heater, filters, pumps, etc. equipment. The equipment is used in petrochemical industry, wet metallurgy, acid alkali production, synthetic fiber, paper and other industrial sectors, can save a lot of metal materials.
6. For the atomic energy industry and defense industry
Graphite has good neutron reduction performance, the earliest as the reducer for atomic reactors, uranium graphite reactor is currently a more application of an atomic reactor. As the power of the atomic energy reactor in the reduction material should have a high melting point, stability, corrosion resistance, graphite can meet the above requirements.
7. Anti - scale anti - rust material.
Graphite can prevent boiler fouling. The test shows that adding a certain amount of graphite powder in the water can prevent the fouling in the boiler surface.. In addition graphite coated metal chimney, roof, bridge, pipeline can be anti-corrosion and rust.
8. Other new uses
1) Flexible graphite products. Flexible graphite, also known as expanded graphite, is a new graphite product developed in the 70's.. 1971 United States successfully studied the flexible graphite seal material, solved the problem of leakage of atomic energy valve, then Germany, Japan, law also began to develop and produce. This product has special flexibility and elasticity except for the characteristic of natural graphite.. Therefore, it is an ideal sealing material, widely used in petrochemical industry, atomic energy and other industrial fields, the international market demand increased year by year.
2) Making half metal friction material. Since the 70 s, the clutch and auto lining have been widely used in half metallic friction materials. Semi metallic friction material is graphite and metal powder, steel fiber, clay powder made of synthetic resin bonding. These automatic liners are mainly used for high-speed equipment, such as airplanes, trucks and brake devices and clutch discs for off-road vehicles
