Introduction to graphite electrodes

Graphite electrode, mainly made of petroleum coke and needle coke, coal tar pitch as binder, calcined, compounded, kneaded, pressed, calcined, graphitized, machined, is released in the form of electric arc in electric arc furnace The conductor that heats and melts the charge of the electric charge can be divided into ordinary power, high power and ultra high power according to its quality index.

Graphite electrode • Instructions for use

1. Damp graphite electrodes should be dried before use.
2. Remove the foam protective cap on the spare graphite electrode hole and check whether the internal thread of the electrode hole is complete.
3. Clean the surface of the spare graphite electrode and the internal thread of the hole with compressed air without oil and water; avoid cleaning with steel wire or metal brush.
4. Carefully screw the joint into the electrode hole of the end of the spare graphite electrode (it is not recommended to directly insert the joint into the electrode removed from the furnace). Do not hit the thread.
5. Screw the electrode spreader (a graphite spreader is recommended) into the electrode hole at the other end of the spare electrode.
6. When lifting the electrode, pad the soft material to the underside of the end of the spare electrode fitting to prevent the ground from damaging the joint; lift the lifting ring with the hook into the lifting ring of the spreader, and lift the electrode to be stable to prevent the electrode from being loosened by the B end. Take off or collide with other fixtures.
7. Hang the spare electrode above the electrode to be connected, and then slowly drop it after aligning the electrode hole; rotate the spare electrode to rotate the screw hook together with the electrode; when the distance between the two electrode ends is 10-20mm, use compressed air again. Clean both ends of the electrode and the exposed part of the joint; when the electrode is completely lowered at the end, it should not be too strong, otherwise the electrode hole and the thread of the joint will be damaged due to the violent collision.
8. Screw the spare electrode with a torque wrench until the end faces of the two electrodes are in close contact (the correct connection between the electrode and the joint is less than 0.05 mm).
Graphite is very common in nature, and graphene is the most intensely known substance in humans, but scientists may still have to spend years or even decades to find a way to convert graphite into large pieces of high-quality graphene "film". The methods that can be used to make a variety of useful substances for humans. According to scientists, graphene has a unique set of properties in addition to its exceptionally strong properties. Graphene is currently the most well-known material for electrical conductivity, which makes it a potential application in the field of microelectronics. Researchers have even seen graphene as a replacement for silicon that can be used to produce future supercomputers.

Graphite electrode ? production process

The petroleum coke and needle coke are used as raw materials, and the coal bitumen is used as a binder, which is prepared by calcination, compounding, kneading, pressing, roasting, graphitization and machining.
