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: Why should supercapacitors use graphite as electrode material?
- Because graphite material, light weight, good thermal conductivity and conductivity.
- 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: 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 difference between graphite electrode and graphite rod
- The difference between an electrode and a rod is that the electrode has a lead conductor, and the rod is not.
- Q: Please senior doubts. The graphite electrode is used in the mold cavity In what case is graphite processing taken?
- Instead of copper as discharge material.1. Electrode design1 can reduce the number of individual electrodes / can be made into a composite electrode2, it can save the electrode clamp system and save the cost2, the electrode processing1, high speed milling rough processing copper block 3 times2, high-speed milling finishing faster than copper 5 times3. Good machinability4, complex geometric modeling can be realized3, light weight, its density is less than 1/4 of copper1, good thermal stability (without deformation)2 can reduce the number of individual electrodes / can be made into a composite electrode3, without deburring4. The electrode is easy to clamp4 、 electric discharge machining EDM1, roughing, the electrode loss is small2, high work removal rate3 can reduce the number of individual electrodes / can be made into a composite electrode4. No pollution to the environment in the electrolyte5, light weight, its density is less than 1/4 of copper6, excellent thermal stability, the electrode does not change7, the fine graphite electrode can be used to produce high quality workpiece surfaceDifferent grades of graphite materials can be used for processing different workpieces
- 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: How can the graphite powder be processed into high quality carburizing agent? Thank you
- If you are through the material can also be screened and then sold, usually 1-5 of the particle size, fine powder can only add adhesive column
- 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: 800KVA and 12500 EAF transformer data graphite electrode furnace.
- The graphite electrode must be roasted by a cathode or anode baking furnace, and a large amount of harmful gas and dust will be produced during the roasting process.
- Q: How about graphite electrode high-temperature oxidation resistant coating?
- Heat resistant coating is generally able to withstand 300 degrees below the temperature, commonly used aluminum heat-resistant paint, high temperature resistance can withstand higher temperatures, such as 800 degrees or more, commonly used silicone heat-resistant paint
