Semi-Graphite Petroleum Coke Sgpc GPC (0.5-5mm 1-5mm) as The Recarburizer of Cast Iron
Petroleum coke can be used in the industries of graphite, smelting and chemical industry depending on its quality. Low-sulfur, high-quality cooked coke, such as needle coke, is mainly used to manufacture ultra-high-power graphite electrodes and some special carbon products. In the steel-making industry, needle coke is an important material for developing new technologies for electric steelmaking. Medium sulfur, ordinary cooked coke, used in large quantities for aluminum smelting. High sulfur and ordinary coke are used in chemical production, such as the manufacture of calcium carbide, silicon carbide, etc., as well as fuel for metal casting.
Application of Graphitized Petroleum Coke
Graphitized Petroleum coke is mainly used for metallurgy & foundry, it can improve the carbon content in steel-melting and casting, Also it can increase the quantity of scrap steel and reduce the quantity of pig iron, or use no scrap iron at all. It's also can be used for brake pedal and friction material.

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 |
