Graphite electrode introduction
Graphite electrodes are used mainly in electric arc furnace steel production. They are presently the only products available that have the high levels of electrical conductivity and the capability of sustaining the extremely high levels of heat generated in this demanding environment. Graphite electrodes are also used to refine steel in ladle furnaces and in other smelting processes.

1,The high power graphite electrode uses Fushun petroleum coke,Japanese imports of needle coke and temperature modified asphalt as raw material,in accordance with the high power graphite electrode production processes,crushing,screening,dosing,kneading,forming,baking,hi pressure impregnation,the second time of baking,graphitization and machining refined.
2,The nipple uses Japanese imports of needle coke,three times of baking processes.
- Q: Is graphite electrode good for foreign trade?
- I do graphite electrode production, but also do trade. The profit depends on the price you talked about. It should be around 2000.
- Q: Why is graphite conductive electrode oxidized?
- The reason for its oxidation is that it is oxidized at atmospheric temperature by reacting with the oxygen in the air
- Q: What are the factors affecting the service life of graphite electrode in ultra high power arc furnace?
- China's graphite electrode quality standard (YB/T4090-2000) to evaluate the quality of the ultra high power graphite electrode is defined 6 physicochemical indexes, including resistivity, flexural strength, elastic modulus, bulk density and linear expansion coefficient as the quality evaluation index, ash as a reference index.
- 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: Graphite powder produced by graphite electrode and what we usually call graphite is a kind of thing?
- Graphite electrode is mainly in petroleum coke, coke as raw material
- Q: How can hydrogen be produced by electrolysis of sodium hydroxide with graphite as an electrode?
- Because there is no hydrogen ions in the molten state of sodium hydroxide, sodium hydroxide and the onlyThis reaction should have occurred,Na+ + e=Na4OH-- 4e=O2+H2O
- Q: The production of one ton of steel required graphite electrode
- The consumption of graphite electrode in steelmaking in arc furnace, according to the different material, different specifications of graphite electrode used (normal power graphite electrode, high power graphite electrode, ultra high power graphite electrode) have relations.
- 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: Carbon graphite electrode and what is the difference?
- The material is composed of carbon carbon, but without graphite, after molding sintering temperature is only more than 1000 degrees, no graphitization.
- Q: What is anodized graphite?
- According to the production method of brush, there are two kinds. One is colored brush, that is, metal graphite brush. One is black brush. The black brush is made of petroleum coke, pitch coke, carbon black, charcoal and natural graphite powder and so on. Some binders (such as coal tar pitch, coal tar and artificial resin etc.) are added to the black brush. The resin binder by curing brush manufactured for high resistance brush, and the calcined product called carbon brush and graphite brush (with natural graphite as the main raw material) graphitised after product called electrographite brush,
