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. It is more and more popular in this filed.
3, apply: Used in electric furnace steel smelting and cast-iron for improving the carbon content
- Q:Why is the battery electrolyte more potassium hydroxide and sodium hydroxide is less used?
- Anode material of nickel cadmium batteries is a mixture of nickel hydroxide and graphite as anode material, sponge cadmium and cadmium oxide powder powder, the electrolyte is usually sodium hydroxide or potassium hydroxide solution. When ambient temperature is high, use a sodium hydroxide solution with a density of 1.17 to 1.19 (15 C).
- Q:What are the hazards of inhalation of graphite dust?
- It must be harmful to human beings! Look at the dictionary of carbon black dust lung disease Description: black carbon pneumoconiosis: long-term inhalation of carbon black dust caused by pneumoconiosis. Carbon black is mainly the quality of easy flying carbon. Although the production has been closed and automated, the phenomenon of dust flying still exists. Therefore, workers who produce and use carbon black may have black carbon pneumoconiosis, the shortest length of onset is 15 years, the longest can be more than 25 years, the clinical symptoms are mild, and the progress is slow, and generally does not affect the ability to work.
- Q:Is the graphite powder poisonous?
- Qingdao Huatai graphite for you to answer, graphite powder itself is no poison, graphite powder is powder, a long time in the graphite powder prone to pneumoconiosis and other occupational diseases, work should bring masks, ventilation conditions, eat more fungus and so on to prevent,
- Q:The principle of a graphite missile
- The graphite missile contains carbon fibers and is highly conductive. After the explosion of carbon fiber floats attached to the high-voltage lines immediately cause transformer short circuit burned, to destroy the enemy's power to.
- Q:Are graphite powders soluble in water, dilute acids, dilute bases, and organic solvents?
- At room temperature, the chemical properties of stone toner are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents;
- Q:How to measure the conductivity of powdered graphite?
- The conductivity of conductive graphite powder was measured by resin methodTo buy some conductive paint resin, add the same amount of conductive graphite powder, and then coated on a board, with digital multimeter to measure its conductivity on the list.
- 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:Graphite powder what is the difference?
- So the pencils are not made of lead, but made of graphite, which prevents the children from damaging their bodies by biting their pencil heads. Hope to adopt!
- 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
- 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.
