Industrial Graphite Petroleum Coke Product Overview
Industrial Graphite Petroleum Coke (GPC) ASTM Standard is a premium carbon material used extensively in steelmaking, foundries, and other high-temperature industrial applications. This product is produced by calcining petroleum coke at high temperatures to enhance its carbon content and improve its graphitic structure, resulting in superior conductivity and stability.
Conforming to ASTM specifications, this GPC material is designed to provide consistent performance, ensuring cleaner melts, improved carburization, and optimized silicon recovery in metallurgical processes. Its low impurity levels help reduce slag formation, resulting in higher-quality metal and more efficient operations.
This GPC material is highly effective for use in electric arc furnaces (EAF), induction furnaces, ladle refining, and other advanced steelmaking processes.
