PRODUCT DETAILS

Graphite electrode is a major conduction material used in the electric smelting industry, which has the properties of superior electric conductivity, thermal conductivity, high mechanical strength, oxidation and corrosion resistance in high temperature. Graphite electrode is typically used in EAF(for smelting steel),submerged-arc furnace(for producing ferrodalloy, pure silicon, phosphor, matte, calcium carbide, etc.)And electric resistance furnace furnace, such as graphitization furnace producing graphite electrodes, glass-melting furnace, electric furnaces producing carborundum, etc.

Q:How to improve the efficiency of graphite electrode milling, please tell me
The technical development of the high-speed machining center lays the foundation for improving the milling efficiency and quality of the graphite electrode, especially for the milling of the small electrode with complicated shape and thin wall. In the EDM mold processing, the graphite electrode needs to be processed by the high-speed machining center (HSM), so the demand for HSM machine tools is also increasing. But for some time, because of the technological developments in hard steel processing, it seems possible to make graphite electrodes an obsolete technology.
Q:How does graphite produce solar cells?
The team at the Massachusetts Institute of Technology has confirmed that electrodes based on graphene and ITO devices are comparable in efficiency. Although the power conversion efficiency of graphene is 4.2% lower than that of a general silicon cell, it will be competitive for special use in the future.
Q:The reason why graphite is used as electrode
The graphite has good conductivity and thermal conductivityThe conductivity of graphite is one hundred times higher than that of ordinary non-metallic minerals. Heat conductivity exceeds steel, iron, lead and other metal materials. The coefficient of thermal conductivity decreases with increasing temperature, and even at extremely high temperatures, the graphite becomes hot.
Q:The original battery is not necessary to form the electrode potential? Why can we use graphite as electrode only? No potential difference.
Indeed, the original battery electrode potential using two different electrodes, produce potential difference, so that the electron flow generated current. Graphite is used as an electrode because of its excellent electrical conductivity and stability
Q:Graphite electrode press device
High power graphite electrodes. Graphite electrodes with a current density of 18 ~ 25A / cm 2 are allowed. They are mainly used in high power arc furnaces for steelmaking
Q:How should carbon deposits be treated?
It is very necessary to clean the throttle valve, clean the nozzle, and clean the carbon in the engine cylinder! However, in order to reduce the trouble of cleaning, it is best to join the regular application of graphene Moqi additive in lubricating oil for engine.
Q:After vacuum melting of quartz crucible, there are three graphite electrode rods. What's the adjustment?
Or did you adjust the electrode when it was installed? There are two electrode distance, two away, causing melting after different lengths.
Q:What's the use of carbon?
Common power graphite electrode. Allows the use of current density of less than 17A/ cm 2 graphite electrode, mainly used for steelmaking, smelting silicon, yellow phosphorus and other ordinary power furnace.
Q:Is graphite flammable?Why do I bake pencil cores with a fever that doesn't burn?
In theory, as long as a certain temperature is reached, any substance can be burned, and the diamond is converted to graphite at 2000~3000 DEG C under anaerobic conditions. That is to say, graphite (flake graphite)
Q:What is the application of wire cutting with graphite electrode?
Machine: wire cutting wire, wire EDM, wire EDM wire is the cutting machine.
