Q: Classification, uses and manufacturers of graphite electrodes: The difference between graphite electrodesMainly from the current, density, resistance, bending strength, ash parameters are measured

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: 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: Is graphite flammable?Why do I bake pencil cores with a fever that doesn't burn?: In anaerobic conditions, the ignition temperature is at least above 3000 degrees. There are many types of graphite, different types of ignition points, and the burning point of pyrolytic graphite...

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: What's the use of carbon?: Common power graphite electrode. Allows the use of current density of less than 17A/ cm 2 graphite electrode, mainly used for steelmaking, smelting silicon, yellow phosphorus and other ordinary power furnace.

Q: The difference between graphite electrode and graphite rod: The difference between an electrode and a rod is that the electrode has a lead conductor, and the rod is not.

Q: How can the graphite powder be processed into high quality carburizing agent? Thank you: If you are through the material can also be screened and then sold, usually 1-5 of the particle size, fine powder can only add adhesive column

Q: What are the factors that affect the electrode wear rate of machine tools?: In the pulse peak voltage, current and pulse width decreased, the electrode loss increase, and the heat produced from the processing of large pulse width, is conducive to the adsorption of copper electrode graphitization induced by carbon, which is commonly referred to as the covering effect".

Q: How can I electroplate iron? I would like to use graphite as an electrode. Iron is plated on graphite with iron solution, so it can be processed into iron parts. I wonder if it can be done: Iron plating can be, with 2 valence iron, but on the graphite joint force is good, it is difficult to say, electroplating is bad, peeling is also common. Relatively speaking, iron parts on nickel plating is relatively simple, also more applicable
