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.

- Q: Use of graphite in steelmaking
- Application of graphite electrode in smelting, alloy steel, iron alloy, graphite electrode, the strong current through the melting zone, the arc electrode into the electric furnace, the electrical energy into heat, the temperature rises to 2000 degrees Celsius, so as to achieve the purpose of melting or reaction.
- Q: What is the difference between pyridine type nitrogen and graphite type nitrogen?
- High purity graphite is said to produce graphite electrode, ash is very low, generally below 10 million.
- Q: Why should the carbon brush for the trolley be made of graphite?
- Graphite conducts electricity and is self lubricant, resistant to wear. As for why, high school chemistry textbooks have ah.
- Q: What are the structures of pyrolytic graphite electrodes? What are their properties and applications? We hope that some details will not be found
- The high purity graphite component is put into the furnace, and nitrogen and methane are produced under vacuum high temperature. Then graphite is shown to produce 10% coating.
- 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: Can high-purity graphite be used as an electrode?
- The utility model has the advantages of small density and suitable tool electrodes for processing large parts or moulds, and the whole quality is small.
- Q: Graphite electrode press device
- Ultra high power graphite electrodes. Use of graphite electrodes with a current density greater than 25A / cm 2. Used primarily in ultra high power arc furnaces
- Q: I used 12V direct current, graphite electrode electrolysis sodium sulfide solution, the anode produced a large number of black material, this is why ah?
- The problem is this. I have done the test of electrolytic copper sulfate, and the anode produced the same phenomenon. Finally, the chemistry teacher told me that it was because the graphite was broken in the process of electrolysis
- Q: What is the composition of petroleum coke and what is its use?
- Medium sulphur and common cooked coke; used in large quantities for aluminium smelting. High sulfur, ordinary coke is used in chemical production, such as the manufacture of calcium carbide, silicon carbide, etc., but also as a metal casting and other fuels. Most of the petroleum coke produced in China belongs to low sulfur coke, which is mainly used for smelting aluminium and making graphite.
- Q: Graphitized anode, cathode and graphite electrode, respectively How can one differentiate and use differently?
- In electrolysis industry, using graphite anode plate as the anode has a history of more than 100 years, the metal anode is in recent decades, the research and application of metal anode in China late last century, only in 70s the technology related to the research and experiment of metal anode, anode on electrolysis industry, mainly through the silver (2%) (0.5%): low silver lead silver alloy, lead and silver tin antimony alloy, lead calcium alloy and lead silver alloy adding nucleating agents and several stages
