What Are The Main Function of Graphite?

1. Graphite as refractory: graphite and its products have high temperature, high-intensity properties, in the metallurgical industry is mainly used in the manufacture of graphite crucible, in steelmaking commonly used graphite as a protective agent for ingot, metallurgical furnace lining.

2. Graphite as conductive material: in the electrical industry for the manufacture of electrodes, brushes, carbon rods, carbon tubes, mercury positive flow of the cathode, graphite washers, telephone parts, TV picture tube coating.

3. Graphite is used as wear-resisting lubricating material: graphite is often used as lubricant in mechanical industry. Lubricating oil is often not used in high-speed, high-temperature, high-pressure conditions, and graphite wear-resistant materials can be at a high sliding speed at 200 temperature, without lubricating oil work. Many of the equipment to transport corrosive media, widely used graphite materials made of piston cups, seals and bearings, they operate without the need to add lubricating oil. Graphite emulsion is also a good lubricant for many metal processing (wire drawing, tube).

4. Graphite has good chemical stability. After special processing of graphite, with corrosion resistance, good thermal conductivity, low permeability characteristics, a large number of used in the production of heat exchanger, reaction trough, condenser, combustion tower, absorber, cooler, heater, filter, pump equipment. Widely used in petrochemical, hydrometallurgy, acid and alkali production, synthetic fiber, paper and other industrial sectors, can save a large number of metal materials.

5. For casting, foundry, die and high-temperature metallurgical materials: Because of the small thermal expansion coefficient of graphite, and the ability to quench the heat changes, can be used as a mold glass, the use of graphite after the ferrous metal to obtain castings size precision, the surface of the high yield, without processing or a little processing can be used, thus saving a lot of metal. The production of cemented carbide and other powder metallurgy process, usually graphite materials made of die and sintered porcelain boat. Crystal growth crucible of monocrystalline silicon, area refining container, bracket clamp, induction heater, etc. are all made from high purity graphite. In addition, graphite can also be used as vacuum smelting graphite insulation plate and base, high-temperature resistance furnace tube, rods, plates, trellis and other components.

6. Used in the atomic energy industry and the National defense industries: Graphite has a good neutron reducer used in atomic, uranium a graphite reactor is currently used more than a atomic. As a power-driven nuclear reactor, the deceleration material should have a high melting point, stable, corrosion-resistant properties, graphite can meet the above requirements. The purity of graphite used as atomic is very high, and the impurity content should not exceed dozens of ppm. In particular, the boron content should be less than 0.5PPM. Graphite is also used in the defence industry to make solid fuel rocket nozzles, nose cones for missiles, parts of cosmic navigational equipment, insulation materials and radiation-proof material.

7. Graphite can also prevent the boiler scaling, the relevant unit tests show that in the water to add a certain amount of graphite powder (about $number grams per ton of water) can prevent the boiler surface scaling. In addition, graphite coated in metal chimneys, roofs, bridges, pipelines can be anti-corrosion rust.

8. Graphite can be used as pencil core, pigment, polishing agent. After special processing of graphite, a variety of special materials can be produced for the industrial sector.

9. Replace copper as an electrode.
