Graphitized Petroleum Coke / Semi-graphitized Petroleum Coke Product Description Petroleum coke granules are categorized into graphitized petroleum coke and semi-graphitized petroleum coke. Manufactured via high-temperature graphitization followed by crushing, milling, screening and iron removal, they are high-end carburizer raw materials for metallurgy. Non-carbon impurities, sulfur, nitrogen and volatile matters in raw coke are decomposed and eliminated under high temperature, while amorphous carbon transforms into lamellar graphite crystalline structure. Featuring black granular or powdery appearance with distinctive graphite metallic luster, the products serve as premium dedicated carburizers for steelmaking and ductile iron casting. Key Characteristics High absorption rate Low sulfur, low nitrogen and low impurity content Homogeneous and stable chemical composition ...

Calcined Petroleum Coke Granules for Friction Materials Particle Sizes: 20–40 mesh, 40–60 mesh, 80–120 mesh, etc. Functions of Petroleum Coke Granules in Friction Materials Adjust porosity and optimize moulding performance   With inherent porous structure, the coke forms interconnected voids during hot pressing to avoid blistering, delamination and cracking of finished products. It improves the compression resilience of the formulation and prevents brittle fracture of brake pads during cold compaction. Stabilize friction coefficient and restrain high-temperature fade   The micro-pores of coke store and conduct frictional heat under high-temperature braking, quickly dissipating accumulated heat. It prevents sharp drop of friction coefficient above 300 ℃ (thermal fade) and delivers stable braking force across full temperature range. Reduce ...
