Fengcheng Ruixing Carbon Products Co., Ltd
1, as refractory material: Graphite and its products have the properties of high temperature resistant, high strength, mainly used in the manufacture of graphite crucible in the metallurgical industry, the graphite is commonly used in steelmaking for ingot protectant, metallurgical furnace lining.
2. Conductive materials: used in the electrical industry for electrode, brush, carbon rod, carbon tube, mercury positive current, graphite gasket, telephone parts, coating of TV tube, etc.
Make wear-resistant lubrication material: graphite is often used as lubricant in the mechanical industry. Lubricating oil can not be used in high speed, high temperature and high pressure conditions, and graphite wear-resisting material can be in (a) 200 ~ 2000 ℃ temperature under high sliding velocity, no lubricating oil. Many devices that carry corrosive media are widely used to make piston cups, seals and bearings using graphite materials. Do not add lubricating oil when running. Graphite milk is also a good lubricant for many metal processing (wire drawing and drawing).
4. Graphite has good chemical stability. Through special processing of graphite, has advantages of good corrosion resistance, thermal conductivity, low permeability, a large number of used in heat exchanger, reaction tank, condensation, burning tower, absorption tower, cooler, heater, filter, pump equipment. Widely used in petrochemical, wet metallurgy, acid and alkali production, synthetic fiber, paper and other industrial sectors, can save a large amount of metal materials.
5, casting, aluminum casting, molding and high temperature metallurgical materials: due to the small thermal expansion coefficient of graphite, and ability to the change of thermal shock, can be used as glass mold, after using graphite black metal casting dimension precision, smooth surface high yield, without processing or make a little processing can use, thus saving a large amount of metal. Powder metallurgy, such as hard alloy, is usually made of graphite materials and ceramic boats used in sintering and sintering. The crystal growth crucible of monocrystalline silicon, regional refining container, bracket fixture and induction heater are all made of High Purity Graphite. In addition, graphite can be used for vacuum smelting graphite insulation board and base, high temperature resistance furnace tube, rod, board, lattice and other components.
6. For the atomic energy industry and the defense industry: graphite has a good neutron moderator for atomic reactors, and uranium a graphite reactor is one of the more used atomic reactors. The deceleration material used as a power reactor should have high melting point, stable, corrosion resistant performance, and graphite can meet the above requirements. The purity of graphite used as an atomic reactor is high and the content of impurity should not exceed dozens of parts per million. In particular, the boron content should be less than 0.5 PPM. In the defense industry, graphite is also used to make solid fuel rocket nozzles, missile nose cones, cosmic navigational components, thermal insulation materials and anti-radiation materials.
7. Graphite can also prevent fouling of the boiler, and relevant unit tests show that adding a certain amount of Graphite Powder (about 4-5 grams of water per ton of water) to the water can prevent the boiler surface scaling. In addition, graphite is coated in metal chimneys, roofing, Bridges and pipelines that can rust and rust.
