Introduction
The High-purity Graphitized Petroleum Coke is made from high quality petroleum coke under a temperature of 2800°C. As a high-purity carbon material, it has characteristics of high fixed carbon content, low sulfur, low ash, low porosity, high absorptive character , no residue will be left and save production cost etc.
This product can be used as carbon raiser (Recarburizer) to produce high quality steel, special steel, cast iron and alloy or other related industry. We can get high quality steel if use it. It can also be used in plastic and rubber as an additive.
Features
The graphitized petroleum coke powder (grain) is made by graphitization heat treatment of high-quality low-ash petroleum coke at high temperature of 2800 ° C or above in vacuum. The product is featured by high carbon content, low hardness, high temperature resistance, large porosity and low heat conductivity coefficient. Compared with the traditional natural graphite and calcined coke, it can obviously improve caking property and stabilize friction coefficient, maintains the stable and comfortable braking process, and reduce the damage to mating plate surface, brake noise, wear and cost, and is an ideal material for the friction material plant.
In order to control the package and quality, we send people to inspect the loading at loading port and take samples for third party inspection for everyshipment, and will keep customers updated about the loading condition and the inspection result.
Graphite petroleum coke is used in producing casting, it can increase the used quantity of Scrap steel and reduce the quantity of Scrap iron, or use no Scrap iron at all, graphite petroleum coke has high absorptive character, no residue will be left, save production cost. It is more and more useful in steel business

FAQ
1, Usage: used to improve the Carbon content in steel-melting and Ductile iron foundry
2, Characteristic: high carbon, low sulfur, with stable effect for improving the carbon content, high absorptive of carbon.
3, apply: Used in electric furnace steel smelting and cast-iron for improving the carbon content
- Q:How to distinguish between iron powder, aluminum powder and graphite powder (pencil core powder), there are two ways
- Method three: in reverse order with method(1) take a little powder and add dilute hydrochloric acid respectivelyIf bubbles are produced and green light is generated, the solution is iron powder (chemical equation Fe+2HCl = FeCl2+H2)The reaction is more intense, there are more bubbles, the color of the solution does not change, it is aluminum (chemical equation 2Al+6HCl = 2AlCl3+3H2)No obvious phenomenon is graphite powder (not reaction)(2) if the difference between the bubble phenomenon is not obvious, then two kinds of powder with magnetCan be the magnet is not attracted by the permanent magnet is iron powder; powder(high school can also use NaOH solution to identify iron aluminum, aluminum reacts to dissolve hydrogen, iron does not respond)
- Q:Crystal graphite of graphite powder
- Pure graphite flake graphite and high directional pyrolytic graphite, which have less defects and larger sizes, can generally be considered as perfect graphite single crystals. Considerable research has been done on the thermal conductivity of such graphite. Under compressive stress, the pyrolytic graphite above 3000K processing, the bulk density is 2.25g/cm, 2.266g/cm is close to the theoretical density of the single crystal, the half width of the diffraction peak (002) show only 0.4 degree angle (mosaic angle), is also very close to the theoretical value of zero. The thermal conductivity of this graphite is shown in table 1. These values are generally considered to represent the corresponding values for single crystal graphite. The thermal conductivity along two principal directions is denoted as lambda a along the layer, and is marked by lambda C along the vertical plane.
- Q:What are the hazards of inhalation of graphite dust?
- The main pathological change was two lung was black, the whole lung has isolated or clusters of small black nodules around the bronchioles and small blood vessels, irregular nodules; around focal emphysema, pleural thickening and adhesion. X - ray was mainly manifested in increased lung markings, with fine mesh fabric and fine nodular shadows, coarse mesh progression increased, often associated with emphysema, China has listed as the occupation scope of carbon black pneumoconiosis disease.
- Q:Are sand and particle powders used for casting quartz sand? Detailed and accurate.
- General small foundry is river sand, quartz sand is also useful. But the cost is higher, if the product is not high, the river sand on it. You have a particle powder quartz powder with clay, coal powder, in what way do you use.
- Q:The graphite powder can replace thermal grease?
- Graphite is non-toxic, but graphite powder is harmful to human body; and graphite is used mostly in conductive products (common battery).
- Q:Does anyone know how to change graphite powder into graphite?! What kind of equipment do you need?!
- As for the equipment used, there are many, and the price is also high, light an oil press will not be possible, there are dipping pot, baking furnace, etc., at least tens of millions of it.
- Q:What are the specifications of the graphite powder used for conduction?
- There are many kinds of specifications. There are 1 grams, 2 grams, 3 grams, which kind do you need?
- Q:How does graphite powder look good or bad?
- Graphite powder is a kind of negative electrode material for batteries.The process of graphite powder, will after the bursting of the raw ore by car to crush the rock breaking machine, and ball mill by flotation, the flotation of graphite ball mill grinding wet material sending selected, wet material will be selected to bagging dry dry machine, shower shower has become dry, dry material is graphite products. Will pour into the dry drying workshop, drying after bagging, namely ordinary graphite powder, the carbon content of the finished product is an average of 90%.The utility model relates to a pencil core, a graphite electrode for a battery, and a lubricant for a cable carA dark gray, metallic opaque opaque flaky solid. Graphite is very soft, creamy feel. It has excellent electrical conductivity
- Q:Phosphoric acid, two aluminium hydride, with graphite powder and mud
- Of a chemical bond, there is a certain minimum energy for molecules can break chemical bonds between the atoms, the energy corresponding to a critical wavelength, can make the chemical bond breaking in the wavelength of light irradiation.
- Q:Does the graphite powder cause explosion? If so, how to prevent the production of graphite products in the workshop?
- Dust produced in the process of production of some factories and mines, especially the dust produced in the processing of some organic matters, will explode and burn under certain conditions.(2) adequate air and oxidizing agents;(3) there is fire or strong vibration and friction.Such as effective ventilation and biological film, dust suppression technology, integrated dust suppression technology, dust removal measures, smoking and fire operations are prohibited. A pressure relief valve or other device is arranged in the outer shell of the equipment, and an explosion containment system is adopted. For factories with dust explosion hazards, the design must be strictly carried out according to the technical grade of explosion protection, and ventilation and dust removal systems shall be installed separately. Often wet cleaning workshop floor and equipment, to prevent dust flying and gathering. Ensure that the system has a good airtight, if necessary, in airtight containers or pipes in the flammable dust filled with nitrogen, carbon dioxide and other gases, in order to reduce the content of oxygen, dust suppression explosion.
