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.
3, apply: Used in electric furnace steel smelting and cast-iron for improving the carbon content
- Q:Know how the colloidal graphite powder comes in
- There are two ways to make colloidal graphite: (1) mechanical method. Natural graphite is crushed and treated with hydrochloric acid and hydrofluoric acid to remove impurities. Added to the aqueous solution of tannic acid, which is repeatedly inverted into paste. Colloidal graphite can be obtained by adding a certain proportion of water and ammonia, and then by ultrasonic treatment to further reduce the particle size. (2) chemical method. After being purified and crushed, the natural graphite is added with concentrated nitric acid and concentrated sulfuric acid and water at 90 DEG C, and then obtained by cleaning, drying, adding water, ethanol, acetone and other dispersing agents to obtain colloidal graphite. Add stabilizer such as sodium oleate, sulfate and so on, so that graphite particles do not agglomerate. Ammonia transfers the graphite colloid to the gum solution and regulates the pH value.
- Q:The axis and drum can use graphite powder lubrication
- This doesn't seem good. Graphite powder is a solid lubricant. It is suitable for heavy equipment lubrication. The axis and drum or low viscosity lubricating grease is better, so fast.
- Q:Is the graphite powder poisonous?
- There are three kinds of substances that fly out of the black spot from the carbon factory:1. Bituminous dust.2. A relatively fine particle of calcined coke (petroleum coke after calcination).3. A fine particle of calcined and graphitized Shi Mofen (calcined coke and bituminous mixture).Both poisonous.
- Q:Can I use super fine stone powder in grease or lubricating oil?
- Yes, it can play a role in increasing extreme pressure. But it has little effect on low temperature and high temperature resistance. It can not play the role of total synthesis of molybdenum disulfide high temperature grease.
- 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. An extruded graphite core with different impregnation treatments
- Q:Does the pencil core go into the baby's face to keep the skin tight?
- If it's obvious, you need to go to the hospital early, otherwise the macula can last for a long time (a few years, or even ten years). This I have experienced (hand stabbed too) for at least more than 10 years, black.
- Q:Can you tin to latex paint
- Can not brush metal thermal expansion and contraction principle is very strong, or how long it will fall off, really want to brush with a small nail unless many small eyes in atoms in the metal, and then dust coat paint brush
- Q:Graphite powder screening process, because with static holding together, resulting in vibration screen plugging network how to solve?
- The other is to install an electrostatic eliminator when the material falls into the vibrating screen. When the material is dropped, the powder static electricity is removed and the mass will not be assembled again.
- Q:How to distinguish between iron powder, aluminum powder and graphite powder (pencil core powder), there are two ways
- Method three: in reverse order with method(1) take a little powder and add dilute hydrochloric acid respectivelyIf bubbles are produced and green light is generated, the solution is iron powder (chemical equation Fe+2HCl = FeCl2+H2)The reaction is more intense, there are more bubbles, the color of the solution does not change, it is aluminum (chemical equation 2Al+6HCl = 2AlCl3+3H2)No obvious phenomenon is graphite powder (not reaction)(2) if the difference between the bubble phenomenon is not obvious, then two kinds of powder with magnetCan be the magnet is not attracted by the permanent magnet is iron powder; powder(high school can also use NaOH solution to identify iron aluminum, aluminum reacts to dissolve hydrogen, iron does not respond)
- Q:Is oxygen allowed in the oxygen pipe?
- Graphite is a stable substance, and oxygen pipes permit graphite
