Graphite Petroleum Coke GPC

Graphitized Petroleum Coke (GPC) – High Carbon Material for Steelmaking & Metallurgy

Graphitized Petroleum Coke (GPC) is a high-carbon industrial material produced by graphitizing calcined petroleum coke at extremely high temperatures. With high fixed carbon, low sulfur, and low ash, GPC is widely used in steelmaking, foundries, and metallurgical processes where precise carbon control is required.

For industrial users, GPC provides stable carburizing performance, high absorption efficiency, and consistent metallurgical results.

Key Characteristics of Graphitized Petroleum Coke

GPC is engineered for demanding metallurgical environments and offers the following features:

• Very high fixed carbon content

• Low sulfur and low ash levels

• High carbon purity and crystalline structure

• Excellent carbon solubility in molten metal

• Stable and predictable carburizing behavior

These properties make GPC a preferred carbon additive in modern steel and iron production.

Applications in Steelmaking

In steelmaking operations, Graphitized Petroleum Coke is used as a recarburizer, providing:

• Accurate carbon adjustment in molten steel

• Fast carbon dissolution and high absorption rate

• Reduced impurity introduction compared to other carbon sources

• Improved steel cleanliness and quality stability

• Reliable performance in electric arc furnaces (EAF) and induction furnaces

Its high carbon purity supports precise metallurgical control and consistent steel chemistry.

Foundry and Metallurgical Applications

GPC is also widely applied in foundries and non-ferrous metallurgy:

• Carbon addition for cast iron production

• Alloy adjustment in metallurgical melts

• Reduction of slag and oxidation losses

• Support for high-temperature refining processes

The graphitized structure allows efficient carbon transfer, even in short melting cycles.

Advantages of Using GPC in Metallurgy

Compared with traditional carbon materials, GPC offers:

• Higher carbon utilization efficiency

• Lower sulfur impact on final metal quality

• More consistent performance across batches

• Reduced slag formation

• Improved cost control in large-scale production

These advantages make GPC especially suitable for high-quality steelmaking and precision metallurgy.
