Product Description:


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.


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:Thermal conductivity and density of graphite powder
For the same type of graphite, the thermal conductivity increases with increasing density, and Figure 11 shows the relation between the density of HDFG and the density of the same graphite.The heat treatment temperature of polycrystalline graphite is mostly made by roasting the semifinished material by high temperature heat treatment. The higher the heat treatment temperature is, the more perfect the crystallite growth is, the La increases, and the thermal conductivity also increases. With calcined petroleum coke and coal tar pitch, roasting sticks made of extrusion, after different heat treatment (HTT), the value of La are shown in Table 4. The axial thermal conductivity will change with temperature is shown in figure 12. The reciprocal of thermal conductivity 1/ lambda is called thermal resistance. At different temperatures, the relationship between the axial thermal resistance of graphite is shown in Figure 13 and l/La / 1/.
Q:The difference between silicone and silicone?
Silica gel and grease are helpful to system cooling material, the difference is that the silica gel with good thermal performance and insulation, and will not lose its stickiness pale yellow translucent glue at higher temperatures, mainly used in the surface of the heat radiating sheet sticking device; and the grease is not sticky, is a liquid emulsion or cream like, its role is to fill the gap between the chip and the heat sink, improve the efficiency of heat conduction.
Q:Why is there a range of electrode powder powder resistivity? The reasons for the high and low are not good.
Read millivolt values and sample height, calculated according to the formula P =UA/IL type resistivity. The resistivity of the conductor is in P, Omega - M; L for voltage measurement distance between two probes for m; A for the conductor cross-sectional area, m2; U, the voltage between two probes for the determination of voltage V; I the strength of the current flowing through the conductors, the resistivity of A. graphite is (8 ~ 13) * 10-6 (/m), high - low note inside magazines. For reference only!
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: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:What binder does the graphite powder form with?
Graphite powder is divided into natural graphite powder and artificial graphite powder, graphite powder made of graphite products, you need to add binders, binders useful for a variety of resins, asphalt and so on. 100~200 C is not called high temperature for the preparation of carbon graphite products, but only resin can be prepared at this temperature.
Q:How much is one graphite used as electrode?
Graphite particles 6800 yuan / ton, graphite fine powder 8000 yuan / ton, you buy 30 yuan / kg is the natural graphite powder? Not made of graphite electrodes. The graphite powder used in the electrode is actually synthetic graphite powder.
Q:Will dust explosion occur in graphite dust? If you have definite or negative judgment, please share it according to data.
Dust explosion condition(1) flammable dusts are suspended in the air at proper concentration to form dust clouds which are often called;(2) adequate air and oxidizing agents;(3) there is fire or strong vibration and friction. Generally believed that the explosive dust as long as the conditions (1) and conditions (2), it means that there are possible signs of the accident.
Q:How can graphite paper be made? Can graphite powder be solidified without brittleness?
Single layer graphite paper is all graphite products, excluding other materials
Q:Does anyone know how to change graphite powder into graphite?! What kind of equipment do you need?!
As for the equipment used, there are many, and the price is also high, light an oil press will not be possible, there are dipping pot, baking furnace, etc., at least tens of millions of it.
