PRODUCT DETAILS

Graphite electrode is a major conduction material used in the electric smelting industry, which has the properties of superior electric conductivity, thermal conductivity, high mechanical strength, oxidation and corrosion resistance in high temperature. Graphite electrode is typically used in EAF(for smelting steel),submerged-arc furnace(for producing ferrodalloy, pure silicon, phosphor, matte, calcium carbide, etc.)And electric resistance furnace furnace, such as graphitization furnace producing graphite electrodes, glass-melting furnace, electric furnaces producing carborundum, etc.

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
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: How to improve the efficiency of graphite electrode milling, please tell me
There are many factors that determine the need to continue producing graphite electrodes, so high-speed machining has become a key manufacturing process in the die manufacturing industry. Compared with the time required for the milling of graphite electrodes, the processing of high rigidity hard steel still takes longer. When milling dies, cavities, and complex 3D surfaces on hard steel, radial runout errors and tool deviations often result in fracture of the tool. When the tool is broken, it will not only stop the continuous processing of the steel, but also affect the quality of the product, which will lead to the scrap of the parts and the waste of the material.
Q: What is the difference between pyridine type nitrogen and graphite type nitrogen?
High purity graphite is said to produce graphite electrode, ash is very low, generally below 10 million.
Q: Electrolytic salt water why use iron as a cathode, all with graphite can not?
The iron electrode is easier to be installed in the electrolytic cell, which is more convenient than the graphite electrode, and the density of the graphite is small. After being adsorbed by hydrogen, the graphite is easy to float up, and the density of the iron is larger. This problem does not exist in the.5
Q: Which department in the steel plant needs graphite in large quantities?
The variety and specifications of graphite electrodes used in modern EAF steelmaking are mainly determined by the technical parameters of the steelmaking furnace. With the development of EAF steelmaking technology, the steel-making technology is developing towards large scale and ultra high power. The graphite electrode is mainly made of large size graphite electrode and ultra high power graphite electrode.
Q: How long is the graphite electrode machining cycle?
Industrial graphite is hard and brittle, and the tool is worn more seriously during machining. It is generally recommended to use carbide or diamond coated cutting tools. When the graphite is rough, the cutter can be directly worked on the workpiece. When it is finished, it is necessary to use light knife to walk quickly to avoid the occurrence of chipping and chipping
Q: Can Naiduo high temperature graphite
Graphite gasket medium: hot water, steam, oil, acid, alkali, ammonia, hydrogen, organic solvents, hydrocarbons, cryogenic liquids, etc..Maximum use pressure of graphite gasket: 30MPa.Service temperature of graphite gasket: -200~650
Q: The graphite electrode made by the machining center adopts cooling method, which is water cooled, oil cooled and blow cold. Which is good?
I had worked on graphite electrodes for 3 years before, and the fact told me that in addition to using the wind to remove the powder, the others were ineffective or disorderly. Because you have to measure size while processing.
Q: Iron and graphite as electrodes and Nacl as electrolyte solutions. Why do they produce electric current? Graphite and iron react not with solution, can they be connected by wires?
Because the metal activity order form sodium potassium calcium magnesium aluminum, zinc and tin lead (hydrogen), mercury copper silver platinum, iron in the front row because of water water hydrogen, ionized hydrogen ions by iron replacement
