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.

HP Graphite Electrode
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: Where is the graphite electrode scrap?
- Finally, a bright white Ar-ICP discharge is formed, especially like a drop of water droplets.
- Q: Will the concentration of electrolytic sodium sulfite be increased with graphite as electrode?
- No, sodium sulfite reacts with the oxygen produced.
- Q: The original battery is not necessary to form the electrode potential? Why can we use graphite as electrode only? No potential difference.
- A galvanic cell is a device that converts chemical energy into electrical energy. Electron transfer not by oxidizing and reducing agents to complete the effective collision between, but the reducing agent loss electron oxidation reaction occurs in the anode, the electron transport to the anode through the external circuit, the oxidant to the anode electron reduction reaction, so as to complete the transfer of reductant and oxidant electrons.
- Q: What's the purpose of the electrode material?When the electrolytic molten state of NaCl is said, what is the use of the graphite electrode and the iron electrode?
- The copper electrode used for finishing size of the copper electrode discharge speed is not fast but spent graphite electrode is relatively smallRequirements of the high surface, the appearance of products are copper electrode discharge processingThe iron electrode is not clear enough to be used
- Q: Why is the production of one ton of ultra high power graphite electrode requires 1.05 tons of coke?
- After calcined to eliminate ash and volatile part of the points in this process will be a lot of weight loss, in the process of crushing mixing in process of baking or graphite in high temperature heat treatment, another part of the impurities were excluded, so the raw material is higher than the rate of finished products.
- Q: How should carbon deposits be treated?
- In this way, can keep the engine seal, to prevent oil because the gap is too large and rampant, buried carbon curse generation "".
- Q: Classification of graphite electrodes
- 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: What are the losses in graphite electrode?
- In what environment is the loss, friction, or in the case of high temperature, high temperature will be oxidized, and if in the case of friction, you can first use more wear-resistant graphite material. So please ask this question clearly, and then answer you, thank you.
- Q: What is the composition of petroleum coke and what is its use?
- Petroleum coke can be used for the manufacture of graphite, smelting and chemical industries, depending on its quality. For example, the quality of cooked sweet coke coke, mainly used in the manufacture of ultra high power graphite electrode and some special carbon products; needle coke in steelmaking industry is an important material new technology development of EAF steelmaking.
- Q: What are pyrolytic graphite electrodes used for?
- The weight is lighter: the density of graphite is only 1/5 of copper. When the large electrode is used for EDM, it can effectively reduce the burden of machine tools (EDM). It is more suitable for applications on large moulds.
