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.

FAQ
1, Usage: used to improve the Carbon content in steel-melting and Ductile iron foundry. It is more and more popular
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:Use of carburizing agents
- The particle size is too fine, easy to burn, too coarse, float on the surface of liquid steel after adding, and it is not easy to be absorbed by steel. The particle size of 0.2-6mm in the induction furnace, the steel and other ferrous metal particles in 1.4-9.5mm high carbon steel, low nitrogen, particle size in 0.5-5mm, and according to the specific needs of the furnace smelting specific types of workpiece so the details of specific judgment and selection.
- Q:Are graphite powders soluble in water, dilute acids, dilute bases, and organic solvents?
- Under heating, the graphite powder is more easily oxidized by acid. At high temperature, it can react with many metals to produce metal carbides, which can smelt metals at high temperature
- Q:Why does an electromagnetic point timer not prick a needle and use toner paper?
- With the needle point than the powder paper friction, many experimental results of!
- Q:What is the simple test method for graphite powder used in casting?
- Mainly depends on its carbon content, hand stick a little bit on the white paper uniform, if there is a clear scratch is graphite powder
- Q:Two simple physical methods are used to identify iron powder and graphite powderHurry up, you need it urgently! Thank you
- A magnet attracts iron powder... Take the same volume of two substances, respectively, in the hands of weighing, the heavier iron powder
- Q:How does graphite powder look good or bad?
- The graphite powder is soft, black and gray, greasy and polluting paper. Hardness is 1~2, along the vertical direction with the increase of impurities, its hardness can be increased to 3~5. The specific gravity is 1.9 ~ 2.3. Under isolated oxygen conditions, the melting point is above 3000 degrees Celsius and is one of the most refractory minerals. At room temperature, the chemical properties of stone toner are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents. The material has high temperature resistance and conductivity, and can be used as refractory materials, conductive materials, wear-resistant and lubricating materials.
- Q:What effect does graphite powder and graphite gas have on people? Also, I smell graphite gas as if I can't breathe. What's the harm to people?
- If it is a long-term work in the environment first, graphite dust masks, the more than 2 eat bananas, like blood. Case said harmful, you can not see any problems with graphite processing. In short, the dust class should pay attention to, and avoid direct inhalation
- 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.
- Q:How to measure the iron content in graphite powder?
- Take a certain amount of samples, adding dilute hydrochloric acid, excessive filtering and drying. The quality of the filter residue. By weighing the quality of the sample quality is the quality of minus slag containing iron. With this value divided by the sample quality, the mass fraction of iron.
- Q:Method for identifying iron powder, aluminium powder and graphite powder
- They can be used to determine the reaction with acid: the same quality, the same mass fraction of dilute hydrochloric acid solution, and then the three kinds of powder into three kinds of solution, graphite powder and hydrochloric acid reaction observed, iron and aluminum powder and hydrochloric acid hydrochloric acid reaction is slow, can react violently, prove that the nature of the most active aluminum iron, the main component of carbon graphite is the most stable chemical properties.
