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. it is well-used
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 apply: Used in electric furnace steel smelting and cast-iron for improving the carbon content
- 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: 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: Can you tin to latex paint
- Yes, it's better to paint with antirust paint and putty,
- 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: How to measure the iron content in graphite powder?
- Excessive amounts of dilute sulphuric acid can be used to measure the amount of gas produced, and then the amount of iron is calculated according to the amount of gas.
- Q: Sunshine door lock winter treatment
- Always keep the lubricant in the locking part of the lock so as to keep the transmission smooth and prolong the service life. It is recommended to check it for half a year or one year, and check whether the fastening screws are loose or not, to ensure the fastening.
- Q: Why should the lubrication of automobile leaf springs be made of graphite grease?
- This ultra high temperature grease in high temperature above 200 DEG when the base oil volatilize slowly, will be attached to the graphite solid lubrication lubrication is formed on the surface of graphite, itself is a kind of solid lubricant for heavy load / load impact or damp / high temperature friction parts and bearing lubrication under the pollution of the environment, to provide maximum anti rust corrosion protection
- Q: Can graphite powder be used as a carburizing agent?
- It is OK to use a machine that processes fish food with high carbon content,
- Q: Graphite and graphite in the end is not a matter I would like to know the graphite and graphite
- Graphite gum APS two, colloidal or semi - colloidal graphite. (a) colloidal graphite, graphite powder from natural or artificial graphite fine powder in water or other media (e.g., alcohol, mineral oil) colloidal suspensions in the form, and can add a few other products (e.g., tannic acid or ammonia) to be stable. Colloidal graphite is usually semi liquid and is used primarily for lubricating products or for its high electrical conductivity. (two) a semi colloidal graphite (i.e., a colloidal suspension of graphite in water or other medium). Semi crystalline graphite can be used to prepare graphite lubricants or to form graphitized surfaces. This class contains only colloidal or semi colloidal suspensions of graphite with graphite as base material in any medium.
- Q: Why can graphite powder conduct electricity?
- Dense crystalline graphite is also called massive graphite. These crystals are crystalline and visible to the naked eye. Particle diameter greater than 0.1 mm. The crystals are arranged in a dense and blocky structure. The graphite is characterized by a very high grade, general carbon content is 60 ~ 65%, sometimes up to 80 ~ 98%, but its plasticity and unctuousness as fine flake graphite.
