Email: sale@zanewmetal.com
Product Overview
Graphitized Petroleum Coke (GPC) Casting Additive is a carbon raiser used in casting production to adjust carbon content during melting. It is produced by graphitizing petroleum coke at high temperature, which improves carbon structure and helps reduce volatile components. In foundry operations, GPC is applied when carbon adjustment needs to be stable and impurity impact must be controlled.
GPC is widely used in cast iron and ductile iron production, especially in induction furnace melting. Carbon correction in casting is not only related to final chemistry. It also affects melt cleanliness, slag behavior, and defect control during pouring. A stable recarburizer helps keep daily melting more consistent, particularly when the foundry is producing repeat batches of the same grade.
ZhenAn supplies premium Graphitized Petroleum Coke (GPC) with 98.5%+ Fixed Carbon. Specially designed for EAF melting and ladle refining, our carbon raiser ensures stable carbon pickup with ultra-low sulfur (<0.05%) to meet the requirements of high-grade steel and foundry production.
GPC is used in casting mainly for:
- carbon adjustment in cast iron melting
- recarburizing in ductile iron production
- induction furnace carbon correction
Compared with regular petroleum coke, graphitized petroleum coke generally provides cleaner carbon input and more stable absorption. In casting, impurity control is important because sulfur and ash can influence slag formation and melt cleanliness. Stable material quality helps reduce fluctuations between heats.
GPC is usually supplied in granules or particles. Proper particle size improves handling and melting efficiency during foundry charging.
