The petroleum coke is the waste residue of the oil refining process, the graphitization is the process which we make petroleum coke into graphite after high temperature treatment , this process is the petroleum coke electricity after the high temperature of 3000 degrees so that the carbon molecular morphology of petroleum coke by irregular arrangement into six square uniform arrangement way, the petroleum coke can be better decomposition in hot metal this way, all of the main carburetants on the market is graphitized petroleum coke. The graphitized petroleum coke is a thing in recent years, although it is not a new product, it’s one of the graphite material , it develops a new purpose because it’s production is simple and…
Carbon felt in the vacuum or inert atmosphere after more than 2000 degrees under high temperature treatment for graphite felt, carbon content than carbon felt, up to more than 99%. At the end of 60s the world has a graphite felt good supply. Because of the different selection of raw graphite felt for pitch based and PAN based graphite felt and viscose based graphite felt three. The Japan Kureha chemical as a representative of the asphalt in the insulation industry mainstream, Europe and the United States insulation felt basically to adhesives based, and China is most clear polypropylene based as raw material. Process of polyacrylonitrile based carbon felt or rayon based carbon felt cut into the desired size, rolled into…
Graphite crucible formation and types of graphite crucible is in crystalline form of natural graphite as the main raw material, plastic refractory clay as binder, with different kinds of clinker with and made the main application of anti flint graphite crucible smelting special alloy steel, molten non-ferrous metal and alloy. In terms of the performance and use of the product, the graphite crucible is a component of the refractory material. Graphite crucible formation and types of graphite crucible is in crystalline form of natural graphite as the main raw material, plastic refractory clay as binder, with different kinds of clinker with and made the main application in smelting special alloy steel, molten non-ferrous metal and its alloy refractory graphite crucible.…
