One of the main uses of graphite is in the production of refractory materials, including Graphite Tile, tantalum, mold cores, mold detergents and high temperature resistant materials. New processes and new technologies for graphite production include artificial graphite, petroleum coke, metallurgical coke and natural graphite.
Color black porous, the main element of carbon, ash content is very low, generally below 0.5%. Petroleum coke is a kind of easy graphite carbon, petroleum coke in the chemical industry, metallurgy and other industries have a wide range of uses, is the production of artificial graphite products and electrolytic aluminum with the main raw materials.
SYNTHETIC GRAPHITE: Synthetic Graphite is the graphitization of CPC to temperatures of over 3000°C. There are essentially three types of Synthetic Graphite: The first is electrographite, which is pure carbon produced from calcined petroleum coke and coal tar pitch in an electric furnace.
2.Graphite factory 3. Introduction: Artificial graphite electrode is made of high-quality low ash materials, such as petroleum coke, needle coke and coal pitch. After calcining, burdening, kneading, forming, baking and pressure impregnation, it is graphitized in a high temperature of over 3000°C, and then treated with machining.
Soft Petroleum Coke (002) We produced soft petroleum coke is optional flexible Coke hardness low porosity of the high oil Coke after high-temperature roasting after treatment and should soften Marche.
Carbon-graphite is a specially formulated, formed and baked mix of petroleum coke, pitch and graphite. Due to the presence of graphite, carbon-graphite extruded and molded grades do not have to be graphitized, thus making the finished product harder and stronger than graphite, and more suitable for mechanical appliions.
Graphite Electrodes and Carbon Electrodes Definition. Using petroleum coke, needle coke as aggregate, coal asphalt as binder, graphite electrode is manufactured with high quality refractory raw material through the production process of calcining, crushing, burden, mixing kneading, extruding, baking, impregnation, graphitization, manufacturing and packing.
