Petroleum coke is mixed with coal tar pitch and extruded and shaped into blocks which are baked to carbonise the pitch and finally heated to 3 000 C to graphitise, a process which aligns the carbon atoms to finally form graphite. This process can take from 60 to
Calcined Petroleum Coke (CPC) is a form of highly electrically conductive, densed Carbon with very low specific Electrical Resistance, and having fixed Carbon of approximately 99.5%. CPC is used extensively as Anode in Alumina Smelters, as Soderberg''s Electrode for Ferroalloy Industries, and in the manufacturing of Graphite/ Graphite Electrodes, and Thermal Paste for Ferro Alloys &
Calcined petroleum coke is made when petroleum coke is calcined, or roasted, just below the melting point. This coke is commonly used in the smelting industry for the creation of metals such as titanium, aluminum and steel.
Graphite electrode is made of petroleum coke and needle coke as aggregate, coal pitch is used as binder, and it is kneaded and formed. A high temperature resistant graphite conductive material produced by a series of processes such as type, roasting, dipping, graphitization, and machining.
20190117 China petroleum coke market continues to be weak in the short term, the price of related calcined coke recarburizer is low, mainly based on volume. In terms of Sinopec, some high-sulfur coke shipments in East China are still satisfactory. Individual
Green Petroleum Coke Green petroleum coke is produced in the following process: - Separate heated crude oil by using the difference in the boiling point of the components. - Distill the residual oil in vacuum and fractionate it into gasoline, kerosene, light oil, etc.
13/6/2020· Raw materials for synthetic graphite fabriion (petroleum coke, pitch coke, carbon black, natural graphite and secondary graphite scrap are loaded and stored in raw materials silos. At the first step the raw materials are pulverized (ground) in crushers and ball mills.
In our advanced facility, we produce petroleum needle coke through a multi-step process, which we continuously monitor, sample and test. Coking Decant oil feed is preheated, separated by fractionation and reheated to temperatures hot enough to induce an endothermic reaction and form green coke.

Natural flake graphite has a melting point above 3000 C, which is one of the most temperature-resistant minerals. In addition, petroleum coke powder can also be obtained by calcining and graphitizing. Artificial graphite powder has high purity (98%-99.9% and
NAME: HD Graphite Electrode MODEL: 200MM Introduction The graphite electrode is mainly made of petroleum coke and needle coke, and the coal asphalt is used as a binder. It is made by calcination, distributing, kneading, forming, roasting, graphitization and
Our firm is engaged in offering a premium quality range of Calcined Petroleum Coke that is suitable for diverse industrial usage. It is extensively used as a deoxidant in steel making industry and appreciated for its low volatile content, high ash constraint, low impurities and superior quality.
graphite powder with melting point of 3850 ± 50 , boiling point of 4250 , even after ultra-high temperature electric arc burning, weight loss is very small. graphite also with thermal small expansion coefficient and at 2000 ℃ temperature strengthe
‘Most graphite is obtained from petroleum coke, i.e., the black tar that remains after all of the useful fuels and lubricants have been removed from crude oil.’ ‘UP to 2,000 jobs will be put at risk if the Government''s proposal to ban bituminous coal and petroleum coke
Graphite, one of the softest materials known, is a form of carbon that is primarily used as a lubricant. Although it does occur naturally, most commercial graphite is produced by treating petroleum coke, a black tar residue remaining after the refinement of crude oil, in an oxygen-free oven.

The main users of low sulfur petroleum coke are carbon plant, the aluminum industry, iron and steel plants. As fuel for the cement plant and electric plant, which need a high caloric value and a good grinding; As raw materials for Aluminum and steel plants or carbon factory, whether as artificial graphite electrode and the raw material of anode paste, both need to control sulfur and volatile.
The sulfur content of petroleum coke and pitch coke cannot exceed 0.5%. Needle coke is also required for the production of high power or ultra high power graphite electrodes. Advantage The advantage of graphite electrode is that it is easy to process, the electricity discharge processing rate is high, and the graphite loss is small.
materials from the carburization efficiency point of view are: synthetic graphites, petroleum coke, natural graphites and the anthracite [4-6]. When the anthracite is added on the molten alloy surface the high efficiency can be obtained, too, but it requires
melting will drive greater usage of coustion energy and more gas tight furnace design in order to reduce energy losses. This will increase oxidation and the thermal stress requirements for graphite electrodes. The quality of the key raw material, needle coke
17/4/2020· Spheroidal Graphite (S.G) Iron is the name given to that cast –iron, where the graphite is present in the matrix in the form of spheroid or globules or nodules. Hence it is also called as Nodular Iron and because of its exceptionally high ductility (with elongation some times as high as 22%) is also referred to as ductile iron.
