Graphitized Petroleum Coke Product Overview
High-purity Graphitized Petroleum Coke (GPC) is a premium carbon additive widely used in steelmaking, ductile iron casting, and other metallurgical processes requiring stable carbon input. Through high-temperature graphitization, GPC achieves excellent carbon purity, improved electrical conductivity, and reduced volatile content.
Its high fixed carbon content and low impurity levels make it suitable for applications where clean carbon sources are essential for achieving precise metallurgical results. GPC is also valued for its thermal stability, fast dissolution rate, and ability to reduce production variability.
This material is used by steel plants, foundries, and industrial smelters aiming to improve efficiency, reduce slag formation, and produce higher-quality metal products.
Key Advantages
- High carbon purity for consistent metallurgical performance
- Excellent graphitization level for strong conductivity
- Low sulfur and ash content
- Fast dissolution in molten metal
- Reduced slag formation and better carbon recovery
- Suitable for large-scale steel and iron production
