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:How do you use graphite powder in copper?
- It is to drill holes on the copper block and pour the graphite into the hole to ensure that the stone toner can not run out and play the role of oil-free lubrication
- Q:How to distinguish between iron powder, aluminum powder and graphite powder (pencil core powder), there are two ways
- Method two: Ignite (ignite in oxygen bottle)Iron sparks, release a lot of heat, and generation of black powderAluminum burns violently, gives off dazzling white light, emits a large amount of heat, and simultaneously produces white solidThe graphite powder is formed to clarify the turbid water of the lime waterMethod three: in reverse order with method(1) take a little powder and add dilute hydrochloric acid respectively
- 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:Is graphite powder conductive?
- The bottom current may be the internal resistance of the battery is too large, in addition to graphite reasons, the contact state of battery cathode and graphite copper check, graphite powder, no contact measurement, the conductivity of no experience, resistance measurement of graphite column can be compared (with the current large and small current comparison test),
- Q:Does graphite allow lubrication of rusted doors?
- Sure。 When we were young, the teacher reminded us that we could use the pencil core to scrape the end and put it into the keyhole to lubricate it.
- Q:Will dust explosion occur in graphite dust? If you have definite or negative judgment, please share it according to data.
- Any object that is crushed will have a surface energy (internal energy), but the temperature will not increase, so the specific heat will become largerFuel burns because its energy is already full (reaching a point of fire)When the object reaches the ignition point, internal energy = (ignition +273.15) * specific heat capacity
- 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:The principle of a graphite missile
- Graphite conducts graphite on the wire to short-circuit the circuit
- Q:Can graphite powder be used for concrete?
- Generally, stone toner is not used for concrete.There is no standard used or not used in this respect.Individuals believe that in order to form black concrete, it is feasible to add a small amount of graphite powder to concrete, but it should be proved to be in conformity with concrete standards and shall be reported to the business management department for approval. In other cases, even graphite powder can be used for concrete and is also a waste of resources. From the point of view of resource saving, graphite powder should not be used in concrete.
- Q:Thermal conductivity and density of graphite powder
- In the formula, P is porosity, and lambda 0 is the thermal conductivity without hole (P=0). This formula is of historic significance. For graphite, the pores are not spherical or more unequal, but of course they do not apply. But it shows that the larger the porosity (the smaller the density), the smaller the thermal conductivity. This qualitative conclusion is correct.
