Specification
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 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.

- Q: Whether the ordinary graphite powder is sprinkled on the electronic instrument can lead to the malfunction of the instrument
- Graphite powder mainly high pure graphite, graphite powder, nano graphite powder, each is toner has a specific map, if abused, graphite powder will have a certain impact on the letter together, Ruida professional build thermal field | graphite graphite graphite | | isostatic graphite graphite mold, hope this the answer can help to you
- Q: What are the specifications of the graphite powder used for conduction?
- In principle, the higher the purity, the better the conductivity. The finer the particle size is, the more dispersed the stone toner is. The better.
- Q: Use of carburizing agents
- The particle size is too fine, easy to burn, too coarse, float on the surface of liquid steel after adding, and it is not easy to be absorbed by steel. The particle size of 0.2-6mm in the induction furnace, the steel and other ferrous metal particles in 1.4-9.5mm high carbon steel, low nitrogen, particle size in 0.5-5mm, and according to the specific needs of the furnace smelting specific types of workpiece so the details of specific judgment and selection.
- 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: Like the wolf, adding graphite powder in the failure of electronic instrument air explosion in aircraft rocket season, really make it
- Unable to do so, although the graphite can make cars, aircraft and other short circuit, but the aircraft is basically insulated, airtight, the engine is not affected. This is the need for film and television work.
- Q: Why is there a range of electrode powder powder resistivity? The reasons for the high and low are not good.
- A cylinder is inserted in the pipe, and the cross section of the pipe is slightly smaller than the inner diameter of the sample tube. The lower cylinder is fixed on the base of the instrument, and the upper cylinder can move up and down in the tube as a prop to pressurize the sample. The sample is located in the insulating casing on the cylinder between the positive and negative pole and galvanometer millivoltmeter are respectively connected to the drum two cylinder, rotary measuring height, driven by the leading screw rod lifting rod to balance, balance level, sample by 3.92MPa pressure, then switch on the current, the current adjustment into the sample to 300mA, then open the switch millivoltmeter,
- Q: Can ultrafine powder iron conduct heat? How many purpose graphite powder can be called superfine stone powder? Pingdu graphite powder which good?
- Ultrafine toner is a thermal conductive function, because ultrafine toner is processed from natural graphite, which inherits the characteristics of natural graphite conduction and heat conduction.
- Q: What is the ratio of the coated sand to the graphite powder? How to improve the refractoriness of precoated sand
- In addition to improve the refractoriness with graphite, can also add red. It also plays a role in increasing refractoriness and reducing gas output.
- 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: Does the graphite powder cause explosion? If so, how to prevent the production of graphite products in the workshop?
- The graphite powder will cause an explosion. The production of graphite products in the workshop by means of centralized collection and fire protection to avoid explosion.The combustible dust explosion, dust explosion limits in encountered heat (fire or high temperature), flame spread instantly throughout the mixing space dust, fast chemical reactions, while releasing large amounts of heat, resulting in high temperature and high pressure, the system of energy into mechanical energy and light and heat radiation, has a strong destructive power. In the dust explosion with aluminum powder, zinc powder, aluminum powder, grinding a variety of plastic powder, organic synthesis of drug intermediates, wheat flour, sugar, wood, dyes, bakelite ash, milk powder, tea powder, tobacco powder, coal dust, dust and other plant fibers to produce production and processing places.
