Production Description:
Graphite electrode is made from the domestic first petroleum coke and high quality needle coke and widely used in the electric arc furnaces for production of alloy steels, metal and other nonmetallic materials, etc. The graphite electrodes include regular power, high power, super high power, ultra high power and square electrode. The range of diameters covers from 200mm to 700mm. Our products own the following characteristics: low electric resistance, good electric and thermal conductivity, high oxidation resistance, greater resistance to thermal and mechanical shock, high mechanical strength, high machining accuracy.

- 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: Where is the graphite electrode scrap?
- Atoms, ions, and electrons collide with each other in strong oscillatory motion to produce more electrons and ions.
- Q: What is the reason that the current cannot be increased when the graphite electrode is used for anode electrolysis?Add calcium chloride and sodium bicarbonate into electrolytic water
- Because in the process of electrolysis of water in cathode electron generated hydroxyl, the alkaline solution increased. But with the hydroxyl reaction of sodium carbonate and sodium bicarbonate, carbonate and calcium ions exist at the same time, must produce the precipitation of calcium carbonate, the ion in the solution is reduced, thereby conductive resistance increases. Thus weakened over time current cannot be raised
- Q: Electrolytic salt water why use iron as a cathode, all with graphite can not?
- When electrolyzed salt water is used, the cations in the solution (H+, ionized by H2O) are moved to the cathode by the electric field force, and electrons are generated at the cathode to produce H2 hydrogen, and the hydrogen H2 generated does not react with iron
- Q: Will the concentration of electrolytic sodium sulfite be increased with graphite as electrode?
- No, sodium sulfite reacts with the oxygen produced.
- Q: How much does a graphite electrode cost about a ton?
- According to purity and quality, the price is 1-6 tons / tonDo not calculate the processing cost
- Q: What are the losses in graphite electrode?
- So tell, this problem is to answer a lot, graphite under high temperature oxidation, generally around 400 degrees, began a slight oxidation, but the human eye is to be observed, with the increase of temperature, the graphite oxide will increase, this time should be used to protect gas or vacuum to protect what you said is, nitrogen protection, and general protection of nitrogen can reach more than 2000 degrees, if the high temperature to 3800 degrees, will you say that vapor formed in graphite surface. To achieve this temperature, it is necessary to add inert gas to achieve, otherwise, can not reach, generally to 4350 degrees, the graphite began to soften.
- Q: How can I electroplate iron? I would like to use graphite as an electrode. Iron is plated on graphite with iron solution, so it can be processed into iron parts. I wonder if it can be done
- Iron plating can be, with 2 valence iron, but on the graphite joint force is good, it is difficult to say, electroplating is bad, peeling is also common. Relatively speaking, iron parts on nickel plating is relatively simple, also more applicable
- 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,
- Q: How about graphite electrode high-temperature oxidation resistant coating?
- The utilization ratio of graphite energy can reach more than 95%. Many kinds of antioxidant paint, it is recommended to directly find their technicians, you can give professional advice, according to the actual situation, the reasonable use of high-temperature oxidation resistant paint.
