What is Graphite Foil? - Graphite foil is a pliable graphite material with anisotropic properties similar to pyrolitic graphite. It is a good thermal and electrical conductor within the plane of the surface but a much poorer conductor through the thickness of the material. It also has a surface reflectivity several times that of ordinary graphite. Graphite foil products are in stock as sheets, discs, rings & rolls in standard, commercial & high purity grades. All items are to customer requirements. Specialty products include gaskets, tape, die cut rings, carbon fiber yarn & foil yarn with cotton or wire core. Graphite foil is an excellent sealing material for high temperature, high-pressure transfer of liquids, gases, steam, chemicals and corrosives. It…
Graphitization process is the key process in the processing of graphite electrode production, Physico-chemical properties of the graphite electrode is largely determined by the temperature of graphitization process, the graphitization temperature shall be above 2500 ℃. Graphitization furnace used in the graphite electrode processing mainly use the direct method which include two types of the furnaces,one is Acheson graphitization furnace,and another one is LWG furnace. 1、Acheson graphitization furnace Its main characteristic is contained into the roasting products constitute furnace resistance together with the resistance of material, the graphitization temperature will be 2000~3000℃.It is still widely used in China now.This furnace is characterized by simple structure, Strong and durable, easy to maintenance which is mainly the graphitization of equipment in the…
Graphite electrodes are usually used for melting metal, such as aluminum melting and copper melting and so on. Graphite electrodes easier processing, and processing speed significantly faster than copper electrodes. For example, the use of milling machining graphite, its processing speed than other metal working 2 to 3 times faster and does not require additional manual processing, and copper electrodes require manpower grinding frustration. Similarly, if the high-speed machining centers graphite electrode, faster, more efficient manner, but also no dust problems. In these processes, select the right tools and graphite hardness can reduce the wear loss and damage of copper tools. If the time is relatively specific milling graphite electrode and copper electrode graphite electrodes, graphite 67% faster than the…
