The role of graphite blocks

1. As refractory materials: graphite and its products have high temperature resistance, high strength properties, in the metallurgical industry is mainly used to manufacture graphite crucibles, in steelmaking commonly used graphite as a protective agent for steel ingots, metallurgical furnace lining.

2. As a conductive material: in the electrical industry used as the manufacture of electrodes, brushes, carbon rods, carbon tubes, mercury positive current device of the positive electrode, graphite gaskets, telephone parts, TV picture tube coating, etc.

3. As a wear-resistant lubrication material: graphite is often used as a lubricant in the machinery industry. Lubricating oil is often not used under high-speed, high-temperature, high-pressure conditions, and graphite wear-resistant materials can be used at a high sliding speed at a temperature of 200 ~ 2000 °C, without lubricating oil. Many equipment for conveying corrosive media, widely using graphite materials to make piston cups, seals and bearings, do not need to add lubricating oil when they run. Graphite milk is also a good lubricant for many metal processing (wire drawing, pipe drawing).

4. Graphite has good chemical stability. After special processing of graphite, with corrosion resistance, good thermal conductivity, low permeability and other characteristics, it is widely used in the production of heat exchangers, reaction tanks, condensers, combustion towers, absorption towers, coolers, heaters, filters, pump equipment. Widely used in petrochemical, hydrometallurgy, acid and alkali production, synthetic fiber, paper and other industrial sectors, can save a lot of metal materials.

5, For casting, sand turning, pressing and high temperature metallurgical materials: due to the small coefficient of thermal expansion of graphite, and can withstand the change of rapid cold and heat, can be used as a casting mold of glassware, the use of graphite after the ferrous metal to get the casting size is accurate, the surface finish rate is high, without processing or slight processing can be used, thus saving a lot of metal. The production of powder metallurgy processes such as cemented carbide, usually made of graphite materials into porcelain boats for stamping and sintering. Crystal growth crucibles, regional refining vessels, bracket fixtures, induction heaters, etc. of monocrystalline silicon are all processed with high-purity graphite. In addition, graphite can also be used as a graphite insulation plate and base for vacuum smelting, high-temperature resistance furnace tube, rods, plates, lattice sheds and other components.

6. used in the atomic energy industry and national defense industry: graphite has a good neutron reducer for atomic reactors, uranium-graphite reactor is currently more used in an atomic reactor. As a powered atomic energy reactor in the deceleration material should have a high melting point, stability, corrosion resistance performance, graphite can fully meet the above requirements. The purity of graphite used as an atomic reactor 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 defense industry to make nozzles for solid-fuel rockets, nose cones for missiles, parts for space navigation equipment, thermal insulation materials, and ray-proof materials.

7. graphite can also prevent boiler scaling, the relevant unit test shows that adding a certain amount of graphite powder in the water (about 4 to 5 grams per ton of water) can prevent the boiler surface from scaling. In addition, graphite applied to metal chimneys, roofs, bridges, pipes can be anti-corrosion and rust-proof.

8. Graphite can be used as pencil refill, pigment and polishing agent. After special processing, graphite can be made into various special materials for use in the relevant industrial sectors.

9. the electrode: graphite instead of copper as an electrode
