In the world of iron, steel, and casting, carbon content determines quality.

Our graphitized recarburizer is refined using a high-temperature graphitization process, offering high fixed carbon content, low impurity levels, and a stable structure.

During the smelting process, it enables rapid absorption and a stable increase in carbon levels, effectively enhancing the quality of molten steel and iron, boosting smelting efficiency, and reducing production costs.

Widely used in:
Iron and steel smelting | Foundry industry | Alloy production

Ensure consistency in every heat—starting with precise carbon adjustment.

🔥 How Petroleum Coke Becomes Calcined Petroleum Coke (CPC)

In oil refining byproducts, green petroleum coke is just the first step.

It contains a high amount of volatile matter, has a loose structure, and unstable purity, making it unsuitable for direct use in high-end metallurgical fields.

So, how is it "upgraded" into high-quality calcined petroleum coke?

⚙️ Key Step: High-Temperature Calcination

In a specialized rotary kiln or pot furnace,

the petroleum coke is heated to a high-temperature environment of 1200°C – 1400°C.

During this process:

🔥 Volatile matter is completely removed

🔥 Residual oil and moisture are completely removed

🔥 The carbon structure rearranges and densifies

⚡ What happens during the structural upgrade?

After high-temperature treatment:

✔ Significantly increased fixed carbon (up to 98%+)

✔ Reduced resistivity and enhanced conductivity

✔ Reduced impurities and higher stability

✔ More dense and uniform particle structure

🏭 Final product: Calcined petroleum coke (CPC)

It has become an important carbon material in the steel and aluminum industries:

Steelmaking carbon raiser
Aluminum anode material
Graphite electrode raw material
Finding industry carbon source raiser petroleum coke mill
