Specification
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. it is playing more and more important role in the industry
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: Can you tin to latex paint
- Can not brush metal thermal expansion and contraction principle is very strong, or how long it will fall off, really want to brush with a small nail unless many small eyes in atoms in the metal, and then dust coat paint brush
- 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 does graphite powder look good or bad?
- High quality graphite powder has high carbon content, superior performance, good quality and wide application range. This is the reason why the quality of graphite powder is higher than other graphite powder.
- Q: Use of carburizing agents
- In the smelting process, due to improper ingredients or improper loading and excessive decarburization, the carbon content in the steel sometimes does not meet the requirements of the top stage. The commonly used carburizing agents include carburized pig iron, electrode powder, petroleum coke powder, charcoal powder and coke powder. When smelting medium and high carbon steel in converter, the oil containing little impurity is used, and Jiaozuo is used as carburizing agent. For BOF steelmaking using recarburizer requirement is high to low fixed carbon, ash, volatile matter and sulfur, phosphorus, nitrogen and other impurities, and dry, clean, moderate size.
- Q: Can graphite powder be found in plastic?
- Can effectively improve these shortcomings of plastic, so graphite powder can be used in plastic, and I hope to help you, I hope to adopt, thank you very much.
- Q: Know how the colloidal graphite powder comes in
- There are two ways to make colloidal graphite: (1) mechanical method. Natural graphite is crushed and treated with hydrochloric acid and hydrofluoric acid to remove impurities. Added to the aqueous solution of tannic acid, which is repeatedly inverted into paste. Colloidal graphite can be obtained by adding a certain proportion of water and ammonia, and then by ultrasonic treatment to further reduce the particle size. (2) chemical method. After being purified and crushed, the natural graphite is added with concentrated nitric acid and concentrated sulfuric acid and water at 90 DEG C, and then obtained by cleaning, drying, adding water, ethanol, acetone and other dispersing agents to obtain colloidal graphite. Add stabilizer such as sodium oleate, sulfate and so on, so that graphite particles do not agglomerate. Ammonia transfers the graphite colloid to the gum solution and regulates the pH value.
- Q: What is graphite powder?
- Graphite is soft, black and gray; greasy feeling, can piece of paper pollution. 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. Under normal temperature and chemical properties of graphite is relatively stable, insoluble in water, dilute acid and dilute alkali and organic solvent; different high temperature reaction with oxygen, carbon dioxide or carbon monoxide; only in halogen fluorine can react directly with elemental carbon; under heating, the graphite powder is easy to be oxidized under high temperature, acid; but with many metal reaction, formation of metal carbides, can smelt metal at high temperature.
- Q: Does graphite allow lubrication of rusted doors?
- Tolerable。 However, there is a premise: rust must be removed with rust.Lock force rust is generally not easy to lock inside the material easily rust off, then need to use oil to rust, rust removing, the graphite powder filling hole, and then the key to rotate back and forth, you can make the door lubrication.
- 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 kinds of graphite powder has it? What's the function?
- The graphite powder can be divided into colloidal graphite powder and graphite powder, both of which are graphite products, and the colloidal graphite powder is colloidal
