G grade Carbon Electrode 500-700 CNBM China Silicon Production

Q: Thermal expansion coefficient of graphite: In the graphite electrode, the national standard, the volume density in more than 1.60 of both high power graphite electrode, of course because of the national standard index is low now, the volume density of normal power graphite electrode factory can reach 1.65, such as Chengde and long carbon factory.

Q: Why graphite can be used as conductive material?: Lubricants can not be used in high speed, high temperature, high pressure conditions, and graphite wear-resistant materials can be at the temperature and at a high sliding speed, without lubricating oil work. Many transporting corrosive media devices are widely used, which is made of graphite material piston ring, the sealing ring and the bearing, they are running, without adding lubricating oil, graphite and many metal processing when good lubricant.

Q: Specification for graphite electrodes commonly used in steel works: General specification for graphite electrode diameter Phi 300 Phi 500mm, Phi Phi 550 - the current usage of 800mm graphite electrodes is also great, the graphite electrode length was between 1600 and 2700mm.

Q: Graphite can be used in acid towers in chemical plants because of graphite: Ultra high power graphite electrode. A graphite electrode that allows current densities greater than 25A/ cm 2 is allowed. Mainly used in ultra high power steelmaking arc furnace

Q: What kind of asphalt is better for natural graphite coating?: The graphite electrode includes: (1) ordinary power graphite electrode. Allows the use of current density below 17A / cm 2 graphite electrode, mainly used for steelmaking, smelting silicon, refining yellow phosphorus, such as ordinary power furnace. (2) oxidation resistance coating graphite electrode. A graphite electrode coated with an antioxidant protective layer is applied to form a protective layer that is conductive and resistant to oxidation at high temperature, thereby reducing electrode consumption during steelmaking. (3) high power graphite electrode. A graphite electrode with a current density of 18 ~ 25A / cm 2 is allowed to be used as a high power arc furnace for steelmaking. (4) ultra high power graphite electrode. Permits use of graphite electrodes with current densities greater than 25A / cm 2. Mainly used in ultra high power steelmaking arc furnace.

Q: MITSUBISHI machine graphite electrode processing, how does not accumulate carbon?: The impact of carbon on the car is quite large, first of all, to reduce the power of the engine, that is, to make the power output uneven and gradually attenuated, in other words, more and more lack of force. Two is to increase fuel consumption, increase your financial burden.

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: Do electroplating experiments, graphite as an electrode, graphite how to pre process to ensure that the coating will not fall, resulting in increased color of the solution: This graphite will eventually wear out, even if you use the nickel plate directly, the nickel plate is still wearing, but compared to graphite than the much better. You should ask the question, the brush plating industry association, oh, they study this stuff all day long.

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: Infeasible!Iron plating is not easy because two - valent iron is not well - controlled with ferric ironGenerally, metal plating with multivalent States is not well controlled

Q: What are pyrolytic graphite electrodes used for?: Discharge consumption; because the spark oil also contains C atoms in the discharge process, high temperature oil spark decomposition of C atom, and form a protective film on the surface of the graphite electrode, graphite electrode loss compensation.
