Graphitized petroleum coke GPC recarburizer

Graphitized petroleum coke GPC recarburizer

short description:

Graphitized petroleum coke recarburizer, also called graphite petroleum coke GPC or artificial graphite, is used to increase carbon for casting. Made from green petroleum coke and processed at 2000-3000 ℃,Graphitized petroleum coke features high carbon 99%min,low sulphur 0.05%max and Low nitrogen 300PPM max.The appearance of petroleum coke is black or dark gray honeycomb structure, and the pores are mostly elliptical. Graphitized petroleum coke is the best carbon raiser in foundry because it can increase carbon efficiently. It’s widely used in steel, brake pads and other kinds of ductile iron or high end casting.

Size is can be 1-5mm, 0.2-1mm, 0.5-5mm, 0-0.5mm or customize.

Advantage of Graphitized petroleum coke GPC

a) High carbon: Fixed carbon of our GPC is higher than 98.5%
b) Low sulphur: Sulphur of high-level recarburizer can reach 0.01%-0.05%. sulphur of Graphitized petroleum coke can reach 0.01-0.03%, When manufacturers produce ductile iron , if there are sulfide residues in the castings, it will destroy the strength of the matrix, which will allow the casting to form slag holes and subcutaneous pore.
c) Low nitrogen : Too high nitrogen content is easy to bring in nitrogen porosity , which is a negative impact on castings. Nitrogen content is between 80PPM and 250PPM .it’s a perfect material for steel strand.
d) High absorptivity : The absorption rate can be as high as 95%. Comparing with anthracite or calcined petroleum coke, the absorption speed of our product is much faster.
e) High graphite crystal nucleus and high graphitization degree.

Shipping,Package and storage

a) Xintan can deliver graphitized petroelum coke below 60 tons within 7 days.
b) 25kg small plastic bag into ton bags
c) Keep it in dry environment, It can be stored over 5 years.

Applications of graphitized petroleum coke

Foundry is the foundation of industry, and material is the core of foundry graphitized petroleum coke recarburizer produced by Hunan Xintan New Material is widely applied in foundry below:
a) Precision machine.
b) Brake pads.
c) Steel.
d) auto parts, like camshaft, cylinder liner and other casting.
As the rise of new energy vehicles, graphitized petroleum coke is also applied in negative electrode material for car batteries
