What are the processing methods for different types of carbon materials

(1) Processing of graphite electrodes. The processing of electrodes can be divided into three processes: boring and rough flat end faces, turning outer circles and fine flat end faces, and milling threads.(2) Processing of conical joints. The processing of conical joints can be divided into six processes: cutting, flat end face, turning conical surface, milling thread, drilling and installing bolts, and slotting.(3) Processing of cylindrical joints. The cylindrical joint can be divided into three processes: cutting, flat end face, and thread milling.(4) Processing of carbon blocks. The processing of carbon blocks mainly involves flat six surfaces.(5) Processing of special-shaped carbon materials. According to user needs, perform cutting, turning, grinding, boring, slotting, and planing. For products with special requirements, more precise processing is required after normal processing.

Material characteristics of graphite powder

Graphite powder is a substance that is very sensitive to chemical reactions. In different environments, its resistivity will change, which means its resistance value will change. However, there is one thing that does not change. Graphite powder is one of the good non-metallic conductive substances. As long as the graphite powder is kept uninterrupted in an insulated object, it will also be electrified like a thin wire. However, there is no accurate number for the resistance value, Because the thickness of graphite powder varies, the resistance value of graphite powder will also vary when used in different materials and environments. Due to its special structure, graphite has the following special properties:1) High temperature resistant type: The melting point of graphite is 3850 ± 50 ℃, and the boiling point is 4250 ℃. Even after being ignited by an ultra-high temperature arc, the weight loss and thermal expansion coefficient are very small. The strength of graphite increases with te

What should be paid attention to when processing refractory materials with flake graphite?

Will room temperature superconductivity become the next graphene

On July 22nd, a South Korean research team published a paper on the preprint website arXiv, claiming to have synthesized the world's first room temperature and atmospheric pressure superconductor, named LK-99.Superconductivity refers to superconductivity. Under normal temperature and pressure, almost all conductors have resistance, resulting in thermal energy loss during current conduction. Superconductors are materials that can conduct current with zero loss due to the disappearance of resistance, and have complete diamagnetism (internal magnetic induction strength is zero), with advantages such as stability, low loss, and fast transmission.Previously, superconducting materials needed to enter the superconducting state at lower temperatures. The keyword "room temperature superconductivity" mentioned by the Korean team in this paper refers to the phenomenon of superconductivity achieved under room temperature conditions. According to the standards of condensed matter physics

Graphite

One of the main purposes of graphite is to produce refractory materials, including refractory bricks, crickets, continuous casting powder, molding cores, mold casting, detergent and high temperature resistance. In recent years, the two important changes in the refractory material industry are that magnesium carbon bricks are widely used in the inside of the steelmaking furnace, and the application of aluminum carbon bricks in continuous casting. The refractory material for graphite is closely connected to the steelmaking industry, and the refractory material consumed by the steelmaking industry around the world.Because graphite has many excellent performance, it has been widely used in industrial departments such as metallurgy, machinery, electrical, chemicals, textiles, and national defense. Can be used as refractory materials. Graphite products maintain the chemical characteristics of the original scales graphite and have strong self -lubrication performance. The characteristics of

Mining and processing of graphite: Technological advances and environmental challenges

The mining and processing of graphite is a complex and delicate process involving multiple technical links and environmental challenges. As the global demand for graphite resources continues to grow, mining and processing technology is also improving, but at the same time, it also needs to face increasingly severe environmental problems.In terms of mining, with the progress of geological exploration technology, people can more accurately locate the location and scale of graphite deposits, and improve mining efficiency. At the same time, the application of mechanization, automation and other technologies has also reduced mining costs and improved production safety. However, the waste rock, waste water and other wastes generated in the mining process have caused a lot of pressure on the environment, and effective treatment measures need to be taken.In terms of processing, the purification, crushing, molding and other processes of graphite are also constantly optimized.
