Specification
Graphite Electrode
Graphite electrode is made from the domestic first class 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, ultra high power and square electrode. The range of diameters covers from 200mm to 800mm. Our products own the following characteristics: low electric resistivity, good electrical and thermal conductivity, high oxidation resistance, greater resistance to thermal and mechanical shock, high mechanical strength, high machining accuracy.
CNBM and its partner have 4 production bases and the annual production capacity of graphite electrodes is 60,000 MT.

- Q: The future of graphene
- Field of semiconductor materials. Graphene is considered to be an ideal material for replacing silicon. A large number of powerful enterprises have developed graphene semiconductor devices. The Han Guocheng Institute has developed a highly stable n type graphene semiconductor that can be exposed to air for a long time. Graphene silicon optoelectronic hybrid chip developed by Columbia University has broad application prospects in optical interconnection and low power photonic integrated circuit. IBM researchers have developed graphene field effect transistors with cutoff frequencies of up to 100GHz, with frequency performance far superior to the cut-off frequency of the most advanced silicon transistors of the same gate length.
- Q: Does the silicon carbide heat plant require a fine structure graphite electrode? What kind of graphite products do you need?
- Silicon carbide graphite is very famous for its high hardness and wear resistance. It is generally used in high wear resistance machinery industry and high wear resistant sealing industry.
- Q: What is the graphite furnace electrode with a diameter of 400?
- The variety and specifications of graphite electrodes used in modern EAF steelmaking are mainly determined by the technical parameters of the steelmaking furnace.
- Q: Can graphite be used as an electrode for electrolysis of silver in silver nitrate?
- Xiaoyi Liyang said the principle is correct, but can get silver? I think we can solve the problem if we take proper measures to get the silver elements, such as separating the anode and the cathode from the salt water!
- Q: Please senior doubts. The graphite electrode is used in the mold cavity In what case is graphite processing taken?
- Because of the great loss of graphite electrode in finishing, it is not suitable to be used as finishing electrode material. Because of the small coefficient of thermal expansion of graphite, it can also be used as a big electrode material in perforation processing.
- Q: What are the losses in graphite electrode?
- In EDM, discharge principle is to remove the workpiece material by using the tool and the workpiece anode spark discharge explosion, spark discharge is bidirectional, not only will the workpiece removal part, forming processing, will cause some loss of electrode. Electrode loss is one of the main causes of machining errors in machining, and is an important technical parameter affecting the accuracy and quality of EDM
- 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
- Q: What about graphite electrodes for steel mills?
- For steel and iron alloys, graphite electrodes are used, when powerful currents pass through electrodes into the melting zone of the electric furnace to produce an arcThe electric energy is converted into heat energy, and the temperature is increased to about 2000 degrees, so as to achieve the purpose of smelting or reaction. In addition, the electrolytic goldWhen the magnesium, aluminium and sodium are used, the anode of the electrolytic cell is also made of graphite electrode. The resistance furnace for carborundum is also made of graphite electrode as the burnerConductive material.
- Q: What is the difference between SGL graphite electrode and graphite electrode in general?
- In fact, the graphite electrode abroad (including Japan) in several ways than we can control the fine, one is pure, another is anisotropic (resistance, thermal conductivity ah) usually do some control, in the strength of domestic now is also doing well, but when we are comparing high quality products, general domestic products it is basically a piece of the indicators are poor
- Q: How large is the permissible overload current per square millimeter of the graphite electrode cross section?
- 9A/mm2 safety current should be bare overhead, 5A/mm2 is obviously insulation lines, the indoor environment standards.
