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. it is more and more widely used in the steel industry.
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: What is the industry standard of graphite powder coating for casting?
- The two is fine, the finer the better, generally with the "eye" as a unit, that is, sieve stone toner used in the screen, square inch area included in the number of holes, the larger the number the better.
- Q: How do you use graphite powder in copper?
- This question is a bit vague, you can say it, is inlaid with copper and graphite, the graphite powder melt into the copper, if it is the former, is easy to do, if it is the latter, it is necessary to copper melting after adding graphite powder, the latter is relatively difficult.
- Q: Is graphite powder conductive?
- The bottom current may be the internal resistance of the battery is too large, in addition to graphite reasons, the contact state of battery cathode and graphite copper check, graphite powder, no contact measurement, the conductivity of no experience, resistance measurement of graphite column can be compared (with the current large and small current comparison test),
- Q: What is the ratio of the coated sand to the graphite powder?
- General additives accounted for 0.1-0.5 of the original sand weight. Different demand, of course, the proportion is not the same, there is no fixed number.
- Q: What does composite graphite mean?
- Flexible graphite products. Flexible graphite, also called expanded graphite, is a new graphite product developed in the 1980s. In addition to its natural graphite, flexible graphite has high temperature resistance, lubrication and other characteristics, but also has a special flexibility and flexibility.
- 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: What is the use of flake graphite in making flake graphite powder?
- Flake graphite powder: natural crystalline graphite, the shape of fish like phosphorus, is a six party crystal system, layered structure, with good resistance to high temperature, conductive, heat conduction, lubrication, plasticity and acid and alkali resistance.
- Q: What mask should be used to prevent stone powder?
- As enterprise owners, should actively take labor protection measures, do not mean this little money, because if workers suffer from silicosis, treatment and late payment of responsibility is the business owner himself. This runs the risk of.
- Q: Graphite powder made of graphite oxide, how much weight gain?
- 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: Why does the temperature rise when the graphite powder is turned on?
- The presence of resistance, melting point at 3850 + 50 degrees C, graphite powder is a very sensitive chemical substances, in different circumstances, his resistivity will change, that is, his resistance value will change
