1. Brief introduction of graphite electrode
Graphite electrode is mainly in the petroleum coke and needle coke, coal tar pitch as binder, calcinations, 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.
2. graphite electrode instructions
A. wet graphite electrode, use before drying.
B. Remove the foam protection cap on the spare graphite electrode hole and check the integrity of the screw inside the electrode hole.
C. 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.
D. Carefully turn the connector into one of the electrodes of the spare graphite electrode (not recommended to be mounted directly onto the electrode in the furnace) and shall not impact the thread.
E. The electrode sling (graphite spreader is recommended) is screwed into the electrode hole at the other end of the standby electrode.
F. lifting the electrode, the electrode to the standby pad fluffer joint end, to prevent the ground damage joints; rings with a hook into the spreader after lifting, lifting the electrode to smooth, prevent the electrode from B and other loose or fixed device collision.
G. 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.
H. Use the torque wrench to reserve the electrode until the ends of the two electrodes are in close contact (the gap 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, in addition to graphene is strong, the one and only has a series of characteristics, graphene or conductive properties of the currently known excellent material, which makes it has great application potential in the field of microelectronics. Researchers even see graphene as a replacement for silicon and can be used to produce supercomputers in the future.
