The advantages of graphite electrode are easy to process, high removal rate of EDM and small graphite loss. Therefore, some customers of group based spark machine abandon copper electrode and use graphite electrode instead. In addition, some electrodes with special shape can not be made of copper, but graphite is easier to form, and copper

The graphite electrode is located in Beijing in the 1990s and has developed earlier. The first enterprise has been adhering to the professional development and production of graphite products. It has advanced numerical control production equipment and processing center, exquisite production technology and complete detection means. Since the early 1990s, due to the excellent performance

Graphite electrode, mainly made of petroleum coke and needle coke as raw materials and coal asphalt as binder, is made by calcining, batching, kneading, pressing, roasting, graphitization and machining. It is a conductor that releases electric energy in the form of electric arc to heat and melt the furnace charge. According to its quality index,

  Graphite is very common in nature, and graphene is the most powerful material known to human beings, but it may still take years or even decades for scientists to find a way to turn graphite into a large high-quality graphene “film”, so that they can be used to make all kinds of useful materials

The physical and mechanical properties of pyrolytic graphite plate depend on its preparation method. Although the material prepared at 2100 – 2400C has high strength, the pyrolytic graphite plate prepared at low temperature has the highest strength. The oxidation resistance of pyrolytic graphite is very strong, and it is more stable along the deposition direction.

During the operation of the electrolyzer, the graphite anode is mainly consumed through the following forms of corrosion. First of all, the electrolyte contains a lot of hydrogen oxide ions and a small amount of sulfuric and hypochlorite ions as impurities, which will discharge on the anode to generate oxygen. The primary oxygen produced oxidizes
