Graphitized Petroleum Coke Product Overview
Graphitized Petroleum Coke (GPC) 1–5mm is a specialized carbon additive widely used in steelmaking, ductile iron foundries, and metallurgical refining operations. The 1–5 mm granule size offers an optimal balance between dissolution speed and carbon recovery efficiency.
Processed at ultra-high temperatures, GPC achieves excellent graphitization, resulting in high fixed carbon, low sulfur, and minimal ash. These characteristics make it a reliable recarburizer for adjusting carbon levels with precision while improving melt cleanliness and overall metallurgical performance.
This material is ideal for converters, electric arc furnaces (EAF), induction furnaces, and ladle treatment systems.
Key Advantages
- Efficient carbon recovery during melting
- Consistent 1–5mm granule size for predictable dosing
- Low ash and sulfur for cleaner metallurgical processes
- High thermal conductivity and graphitic structure
- Fast dissolution in molten iron and steel
- Suitable for both primary steelmaking and secondary metallurgy
