Item specifice
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 advise that more steel plants can use GPC. 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
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:Distinguish iron powder and graphite powder by chemical method
- Add dilute sulfuric acid, there is a bubble generated iron powder, the phenomenon is Shi Mofen
- Q:How to identify iron powder and graphite powder in a simple way?
- Can also take the first touch, using magnets to attract or drop method with acid identification of three substances. [a] analytical method (first touch after magnet): touch the two kinds of powder by hand, are oily powder graphite powder, and then take the other two kinds of powder with a magnet, the magnet can be as for iron, can not be sucked up into powder;
- Q:What mask should be used to prevent stone powder?
- As an enterprise employee, we must actively advocate the right of labor protection to the enterprise owner, and the stone powder can be worn with industrial masks
- Q:Refractive index and absorbance of graphite powder
- I have already said, the color change, that change the material inside, you have not had the measured absorbance of the substance determination in you have set the wavelength of the sum of the original material, but a new generation of absorption material and the residual absorbance. The original substance must have been reduced, and its contribution to absorbance is correspondingly reduced, but the newly formed material may have a stronger absorption at this wavelength, so the overall result is an increase in absorbance. If you want to use absorbance analysis, you must select a suitable wavelength so that only the material you wish to measure at this wavelength is absorbed without interference from other substances.
- Q:How many kinds of lubricating graphite powder can be added to the car engine?
- Graphite particles, such as sand, will not touch iron, nor oil, the dispersion is very good. Small enough graphite particles, even if the oil back to the oil pan, but also still exist between iron and iron (pressed, want to run, can not run away ah).
- Q:It's hard to remove a lot of graphite powder on the glass cake. Who has a good way to remove the graphite powder above?
- Suggestion: use a certain amount of concentrated nitric acid infiltrated graphite part, nitrate solution the best there is a certain amount of 1-2 weeks (timing can also be placed with a glass rod, pour stirred) acid, diluted with water to acid and then scrub brush. Because the temperature nitric acid reaction is very slow, but the long-term infiltration, the graphite surface. Especially with the glass contact surfaces may be immersed in a small amount of acid, oxidation, then scrub may have the effect.
- Q:Sunshine door lock winter treatment
- Check the locking gap between the lock body and the locking plate regularly, whether the lock tongue is matched with the height of the locking plate hole or not, the optimum clearance between the door and the door frame is 1.5mm-2.5mm. In case of any change, the position of the door hinge or the lock buckle shall be adjusted. At the same time pay attention to the weather (spring wet, dry in winter) caused by cold contraction, thermal expansion, to ensure that the door and door frame, locking body and the locking plate gap reasonable coordination, in order to ensure the smooth use of locks. When you buy, you can ask the manufacturer directly.
- Q:What does composite graphite mean?
- Flexible graphite is prepared into graphite powder as a kind of simple, while the composite graphite is graphite powder with one or more other medium mixed products, their preparation materials are different, the application is different, the above information is a reference to Qingdao Huatai graphite.
- Q:How can the antirust graphite powder used for locks be operated? Where is it painted?
- In the process of switching the door locks on weekdays, the best holding handle lock tongue into the lock, closed the door and then let go, don't bang the door, otherwise it will reduce the service life. Do not use wet cloth to wipe the lock and handle, because some metallic lock will rust; lock alloy material will lose coating worn, beautiful appearance.
- Q:What binder does the graphite powder form with?
- Graphite powder is divided into natural graphite powder and artificial graphite powder, graphite powder made of graphite products, you need to add binders, binders useful for a variety of resins, asphalt and so on. 100~200 C is not called high temperature for the preparation of carbon graphite products, but only resin can be prepared at this temperature.
