Calcined Petroleum Coke (CPC) is a premium-grade carbon additive specifically engineered for high-performance steel casting, foundry, and metallurgical operations. Produced through the rigorous thermal treatment of green petroleum coke at temperatures between 1200°C and 1350°C, this material undergoes a structural transformation that removes volatile matter, significantly enhancing its carbon purity, thermal stability, and overall chemical consistency.
As a critical recarburizing agent, CPC is utilized to precisely adjust and increase carbon levels in molten iron and steel, ensuring the final metallurgical properties meet stringent industrial standards. Its superior density and optimized mechanical strength make it an indispensable resource for producers aiming to improve production efficiency, reduce waste, and maintain the highest levels of material cleanliness in high-end steel manufacturing.
