Graphite electrodeAdd time：2018-01-31
Graphite electrode is mainly in the petroleum coke and needle coke, coal tar pitch as binder, calcination, mixing, kneading, pressing, baking and graphitization, and made the processing machine, is a conductor in an electric arc furnace to form arc release electricity for heating and melting of the charge, according to the quality index level, can is divided into ordinary power, high power and ultra high power.
1. A wet graphite electrode, which should be dried before use.
2, remove the foam plastic protective cap on the hole of the spare graphite electrode and check whether the thread is complete in the hole of the electrode.
3, compressed air oil and water to clean up the spare graphite electrode surface and the hole threads; avoid using wire or metal brush cleaning cloth regiment.
4, the joint shall be carefully screwed into the electrode end of the spare graphite electrode （it is not recommended to directly connect the connector to the electrode hole in the furnace）， so it is not allowed to impact the thread.
5. The electrode hanger （recommended by graphite material） is twisted into the electrode hole on the other end of the standby electrode.
6, when lifting the electrode, cushion the soft part to the bottom of the backup electrode assembly, so as to prevent the ground from damaging the joint. After hoisting the hook into the lifting ring of the hanger, it will hang up, and the electrode must be stable to prevent the electrode from loosening from the B end or to collide with other fixed devices.
7, the electrode to be connected to standby hanging above the electrode, electrode alignment hole slowly after falling; rotating standby electrode, the spiral hook electrode together with rotation in two decline; the electrode surface is 10-20mm, again with the compressed air cleaning electrode two and exposed part of the joint end; at last completely decentralized electrode. Not too hard, otherwise because of violent collision, will cause the thread electrode hole and joint damage.
8. A torque wrench is used to twist the standby electrode until the end face of the two electrodes is in close contact （the correct connection between the electrode and the joint is less than 0.05mm）。
Graphite is very common in nature, and graphene is the highest intensity substance known to man, but scientists may still take several years or even decades of time, to find a way to change the graphite into a large high quality graphene thin film, which can manufacture all kinds of useful substances for human use. According to scientists, graphene is not only exceptionally strong, but also has a series of unique characteristics. Graphene is also known as the best conductive material at present, which makes it have great potential in the field of microelectronics. Researchers even think of graphene as a substitute for silicon, which can be used to produce a future supercomputer.
