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

Green petroleum coke is the raw by-product of oil refining. CPC is produced by heating green coke to 1200-1350°C to remove volatile matter, resulting in higher carbon purity, lower moisture, and better stability for metallurgical use.
CPC offers a superior balance of high fixed carbon, low sulfur, and low ash. This minimizes contamination in the molten steel while ensuring rapid and efficient carbon absorption.
By providing a stable and pure carbon source, CPC helps in achieving the precise chemical composition required for specific steel grades, improving the mechanical properties and cleanliness of the metal.
Yes, CPC is widely used in aluminum production, as a raw material for manufacturing graphite electrodes, and in various other high-temperature metallurgical applications.
CPC should be stored in a dry, well-ventilated area to prevent moisture absorption and contamination, ensuring its high purity remains intact until it is added to the furnace.
Absolutely. We offer various specifications and grades of CPC that can be customized based on your specific furnace conditions and industrial requirements for optimal absorption.
