Graphite used for EDM machining is an isotropic material with a grain size ranging from a few microns to about 20 microns. In the 1970's, improvements made by graphite manufacturers (isotropic properties, consistent quality, large size billets) combined with the emergence of EDM machines equipped with iso-plus generators, allowed graphite to become the most commonly used material for EDM machining electrodes.Graphite has many advantages that have made it the material most widely used for EDM electrodes. Graphite is made up of carbon particles that are put through a graphitizing process to produce graphite. The smaller the particle size is, the better the graphite. Graphite can be purchased in big blocks, and then cut up to be machined; or it can…
The performance of the graphite crucible with excellent wear resistance, thermal conductivity and electrical conductivity, and so on. Use the graphite crucible, not only can improve the service life, reduce the current consumption, but also can save energy and reduce the system load. At the same time, the graphite crucible for energy saving, environmental protection also play a very important role. Based on the above advantages, graphite crucible factory in tianjin is also our very reliable manufacturer. Graphite crucible is made from natural high quality graphite refined but become, have good thermal conductivity and high temperature resistance, high temperature environment used in the thermal expansion is not only the number is small, but also has thermal shock resistance strain performance,…
1, For the refractory material: graphite article having properties of high temperature and high strength, the metallurgical industry mainly used to manufacture a graphite crucible, commonly used in the steel ingot of graphite as a protective agent, a metallurgical furnace lining. 2, As the conductive material: the electrode, the cathode brushes, carbon rod, carbon tubes, mercury positive converter, graphite gaskets, phone parts, television picture tube coatings used for manufacturing in the electrical industry. 3, For wear and lubrication materials: graphite as a lubricant in the machinery industry often. Lubricants are often not on the premise of high speed, high temperature, high pressure use, and the wear-resistant material may be graphite (a) 200 ~ 2000 ℃ temperature at high sliding speeds,…
