Q:Classification, uses and manufacturers of graphite electrodes: Graphite as electrode(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.(2) lighter weight: the density of graphite is only 1/5 of copper. When large electrode is used for discharge machining, it can effectively reduce the burden of machine tools (EDM). It is more suitable for large-scale die applications.

Q:What is the application of wire cutting with graphite electrode?: With the development of science and technology, the machine manufacturing technology has undergone profound changes. Due to the social demand for diversification of products is more intense, more varieties, small batch production increasing proportion in WEDM by traditional processing equipment has been difficult to adapt to the processing of high efficiency, high quality, diversified requirements, CNC technology should be used

Q:800KVA and 12500 EAF transformer data graphite electrode furnace.: Graphite project: Project Description: steel furnace and iron smelting furnace, ferrosilicon smelting, electrolytic aluminum and so on, all use large surface graphite electrode.

Q:I remember the more lively metal, the electron?: C is a salt solution of copper metal because copper is first reduced to a single element on a graphite electrode.Moreover, the addition of dilute sulfuric acid has a H2 emission, then a H of the previous metal.

Q:Electrolysis of CuCl2 solutions with graphite electrodes: The energization is the electrolysis of CuCl2 solutions, i.e., redox reactions. So you can't mix ionization and electrolysis.

Q:Electrolytic salt water why use iron as a cathode, all with graphite can not?: From an economic point of view, the storage amount of iron is much larger than that of graphite, graphite iron is cheaper and easier to get.

Q:What are the structures of pyrolytic graphite electrodes? What are their properties and applications? We hope that some details will not be found: The high purity graphite component is put into the furnace, and nitrogen and methane are produced under vacuum high temperature. Then graphite is shown to produce 10% coating.

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: I can only use the experience of the past to tell you that if you want to save money easily, the time can be considered as the costA thick graphite stick; inexpensive

Q:What is the striking electrode in the die making? Where is the technical point?: Technology of EDM should master the characteristics of electric discharge between tool electrode and workpiece is not in direct contact, but there is a gap, the gap is generally between 0.05~0.3mm, sometimes may reach 0.5mm or more, full of fluid, processing by high voltage pulsed discharge, the discharge of corrosion the workpiece.
