2. Introduction of Graphite Electrodes
G-High Graphite Electrodes have the properties of superior electric conductivity and chemical stability, high mechanical strengt
G-High Graphite Electrodes are made from Petroleum Coke and Needle Coke, using Coal Tar Pitch as agglutinant, produced through the process of calcining, mixing, kneading, compressing, roasting, graphitization and machining, etc.
G-High Graphite Electrodes have the properties of superior electric conductivity and chemical stability, high mechanical strength, less impurity, seismic performance in high temperature. G-High Graphite Electrodes are mainly used for steel-making in electric furnaces, mineral hot furnaces and electric resistance furnaces.
Graphite Electrodes conduct electric current into the furnace. Electric current produces arc in the smelting district, when the temperature increases to about 2000°C, smelting begins. Our series of Graphite Electrodes are applicable to the common furnaces and high power furnaces with high voltage and short arc. G-High Graphite Electrodes are classified into three classes.
NP Graphite Electrodes: mainly used in common power electric ovens for smelting steel, smelting silicon and smelting yellow phosphorus;
HP Graphite Electrodes: mainly used in high power electric ovens for smelting steel;
UHP Graphite Electrodes: mainly used in ultra high power electric ovens for smelting steel.

- Q: What is the striking electrode in the die making? Where is the technical point?
- Electrical discharge machining (EDM) is a spark discharge in a liquid medium at a lower voltage range to meet the required shape and size.
- Q: Thermal expansion coefficient of graphite
- Thermal expansion coefficient (100 degrees Celsius --600 degrees Celsius) diameter 200--500 graphite electrode body is not greater than 2.410 of the negative four times per degree Celsius
- Q: How to improve the efficiency of graphite electrode milling, please tell me
- The technical development of the high-speed machining center lays the foundation for improving the milling efficiency and quality of the graphite electrode, especially for the milling of the small electrode with complicated shape and thin wall. In the EDM mold processing, the graphite electrode needs to be processed by the high-speed machining center (HSM), so the demand for HSM machine tools is also increasing. But for some time, because of the technological developments in hard steel processing, it seems possible to make graphite electrodes an obsolete technology.
- 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: How to solve the problem of graphite electrode being crushed during electrolysis
- There's no way. It's an industrial problem, and that's how graphite works.
- Q: Does the silicon carbide heat plant require a fine structure graphite electrode? What kind of graphite products do you need?
- But because the silicon carbide is too hard, it is difficult to machining, good workability, such as non special requirements, using graphite instead of silicon carbide, instead of the effect is not good, but can use a silicon carbide, easy processing, small life than silicon carbide.
- 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: Electrolytic water solution, two electrodes are graphite electrode, the negative electrode can produce large amounts of hydrogen, the anode does not produce half of oxygen, and only a small amount of it?
- Anodic iron is directly oxidized without oxygen generation
- Q: How does graphite produce solar cells?
- The team at the Massachusetts Institute of Technology has confirmed that electrodes based on graphene and ITO devices are comparable in efficiency. Although the power conversion efficiency of graphene is 4.2% lower than that of a general silicon cell, it will be competitive for special use in the future.
- Q: After vacuum melting of quartz crucible, there are three graphite electrode rods. What's the adjustment?
- The shorter one is the farther away from the other, and the shorter one is the shorter one
