Factorydirectly 98% Carbon Graphite Recarburizer /Recarburizer
Graphited petroleum coke is made by calcined petroleum coke. The main process is the graphitiztion in the graphitization furnace. Graphitized petroleum coke is a good quality recarburizer product with low nitrogen Characteristics.
Graphite petroleum coke is widely used in special casting processes as a recarburiser, in particular in manufacturing high-quality ductile and grey cast iron products with precisely controlled sulphur content, as well as in other applications.

Difference of CPC Calcined Petroleum Coke and GPC Graphitized Petroleum Coke
| Appearance | In appearance, the calcined coke has an irregular shape, while the graphitized petroleum coke has a darker and brighter color. |
| Application | Graphitized petroleum coke and calcined petroleum coke are used in steel smelting and casting manufacturing industries, but graphitized petroleum coke has the advantages of low sulfur, low nitrogen and high carbon compared with calcined coke, and the metal luster is stronger. |
| Manufacturing technique | Graphitized petroleum coke is produced when the internal structure changes at a high temperature of about 3000 degrees, and the temperature of calcined coke is about 1300 degrees. |
The difference between CPC Calcined Petroleum Coke Recarburizer and GPC Graphitized Petroleum Coke Carburant
| Raw Materials | petroleum coke |
| Smelting Environment | Graphitized carburizer is produced in graphitized smelting furnace at a temperature of about 3000 ° C |
| The post-calcined petroleum coke carburizer is produced at a temperature of more than 1500 ºC in the smelting furnace after forging | |
|
Fixed Carbon Content |
Graphitized carburizer fixed carbon is generally about 98%, the highest can reach 99% |
| The fixed carbon of calcined petroleum coke carburizer is generally about 98.5%. | |
| Sulfur Content | The sulfur content of graphitization carburizer is generally between 0.03-0.06%, and generally 0.05% is more. The absorption rate is generally between 90% and 95%. |
| The sulfur content of calcined petroleum coke carburizer is generally about 0.5%. The absorption rate is generally between 80% and 90%. | |
|
Smelting Time |
The smelting environment of graphitized carburizer is longer than that of calcined petroleum coke carburizer |
