DESCRIPTION
Calcined petroleum coke (CPC) is a high-quality carbon material that is used as a key raw material in the production of graphite electrodes for the steel and aluminum industries. The process of calcining green petroleum coke removes volatile matter, moisture, and other impurities from the raw coke, leaving a high-purity carbon material that is ideal for use in the production of graphite.
The production of graphite electrodes involves mixing CPC with other materials, such as coal tar pitch and recycled electrodes, to form a paste that is then molded into the desired shape and baked in a high-temperature furnace. The resulting graphite electrode has excellent electrical conductivity, thermal conductivity, and chemical stability, making it an essential component in electric arc furnaces used for steel and aluminum production.
When selecting CPC for graphite production, several properties are important, including:
- Fixed Carbon (FC): The FC content of CPC should be above 98% to ensure a high-quality graphite electrode.
- Volatile Matter (VM): The VM content should be as low as possible to minimize the risk of cracking or breaking during the electrode baking process.
- Ash Content: The ash content should be low to minimize the impurities in the final graphite electrode, as impurities can affect the electrode’s performance and durability.
- Particle Size Distribution: The particle size distribution of CPC can be tailored to meet the specific requirements of the customer’s graphite production process.
- Sulphur Content (S): The S content should be as low as possible to avoid contamination of the molten metal during the steel or aluminum production process.
