HP Graphite Electrode
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:Synthesis techniques of carbon nanotubes
- The synthesis techniques of carbon nanotubes are mainly arc method, laser ablation (Zheng Fa) method, catalytic cracking or catalytic chemical vapor deposition (CCVD), and directional control growth method based on various synthesis techniques.
- Q:After electrolysis of CuCl2 solution with graphite electrode for a period of time, we can observe that the graphite surface attached to the DC power supply is attached to the red material,And will the color of the solution be deep or shallow?
- Negative poleThe color becomes lighter (the copper ion gets electrons in the cathode and becomes copper)
- Q:What is the difference between pyridine type nitrogen and graphite type nitrogen?
- In fact, this problem is very simple, the carbon graphite is six square lattice ordered, natural graphite and artificial graphite is divided into two kinds: the classification of natural graphite flake graphite and graphite is earthy, basically it is not forming soil shaped graphite graphite, are rough machining, the battery core and do more. The use ratio of flake graphite.
- Q:Why graphite can be used as conductive material?
- Graphite used in the electrical industry requires a high degree of particle size and grade. Such as alkaline batteries and some special electric carbon products, requiring graphite particle size control within the scope of the project, grade above, harmful impurities are required in the following. The graphite used in a picture tube for television is required below. As a wear-resistant and lubricating material, graphite is often used as a lubricant in the mechanical industry.
- Q:Why should supercapacitors use graphite as electrode material?
- Because graphite material, light weight, good thermal conductivity and conductivity.
- Q:What are pyrolytic graphite electrodes used for?
- (1) the processing speed is faster: normally, the mechanical processing speed of graphite can be 2~5 times faster than copper, while the discharge processing speed is 2~3 times faster than copper;More material is not easily deformed: obvious advantages in the processing of thin electrodes; copper softening point at about 1000 degrees, easily deformed by heat; graphite sublimation temperature is 3650 degrees; the thermal expansion coefficient of copper is only 1/30.
- Q:Graphite electrode in milling machine processing, dust is especially big, boot 5 minutes, workshop can not open the figure, what is the solution?
- Connect the fan with a thicker pipe and suck it out of the workshop. The air inlet is mounted on the milling head. Reduce milling speed properly.
- 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
- The reason is that the resistance increases continuously, the number of ions is limited, and the conductivity is limited
- Q:In EDM, the electrodes are made of graphite and copper. Please tell us the difference between them
- For operators, copper is certainly better, graphite will have dust, the human body has serious harm
- Q:Specification for graphite electrodes commonly used in steel works
- In general, the graphite electrode used in steelmaking furnace is mostly made of ordinary power and high power graphite electrode. Now, the use of ultra high power graphite electrode increases year by year, accounting for almost half of the graphite electrode.
