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
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:Is the graphite powder produced with sulphuric acid?
- Not only by crushing crusher can achieve, such as high purity stone toner, expanded graphite by sulfuric acid and other chemical methods for purification, preparation and so on
- Q:Like the wolf, adding graphite powder in the failure of electronic instrument air explosion in aircraft rocket season, really make it
- If you want to hit the plane down, EMP is more practical! Besides, it is also expensive than with stinger!
- Q:The processing technology of graphite powder is different, will the price of graphite powder be different?
- The transportation cost of graphite powder is different: in different areas, transportation costs and prices are different, which will lead to more change in the price of graphite powder.
- Q:Can graphite powder be found in plastic?
- In the plastic production process, to join Qingdao Huatai graphite powder, because the plastic with graphite powder, high temperature resistance, lubrication performance, good wear resistance
- 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:Can I use super fine stone powder in grease or lubricating oil?
- Not really. It depends on the amount of graphite powder. If the graphite powder forms a continuous through zone, it can be considered a conductor.You can use lubricating oil, preferably not with graphite, which will cause the sliding rheostat to fail
- Q:What is graphite powder?
- Graphite is a crystalline mineral of carbonaceous elements. Its crystalline framework is hexagonal layered structure. The distance between each network layer is 340pm, and the distance between the carbon atoms in the same network layer is 142pm;. Of the six Fang system with a complete lamellar cleavage. The cleavage surface is mainly based on molecular bonds, and has weaker molecular attraction, so its natural floatability is very good.Graphite and diamond, carbon 60, carbon nanotubes are carbon elements, they are allotropes.
- 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:Graphite powder what is the difference?
- Lead chemical symbol Pb, belonging to heavy metals, toxic to the human body, excessive intake of lead will accumulate in the body, the body can not take the initiative to discharge, a great harm.
- Q:What is the ratio of the coated sand to the graphite powder? How to improve the refractoriness of precoated sand
- Or change the sand species, change the high refractoriness sand species, this cost is relatively large.
