5mm Graphitized Petroleum Coke Carbon Additive
What the Graphitized petroleum coke Is
Our 5mm Graphitized Petroleum Coke (GPC) Carbon Additive is produced by graphitizing high‑quality petroleum coke at temperatures above 2,800°C, resulting in a highly ordered carbon structure that enhances reactivity and thermal conductivity in molten metal. This 5mm GPC grade is engineered for steel plants and foundries seeking precise carbon control, as its uniform particle size sinks reliably into the melt, enabling rapid carbon diffusion and high recovery rates while reducing overall consumption of Graphitized Petroleum Coke.
With low sulfur and ash content, GPC supports cleaner steelmaking by minimizing gas formation, floating losses, and slag interference, helping maintain strict chemical standards in both steel and iron production. Suitable for EAF, induction furnaces, ladle refining, and cupola systems, the consistent 5mm size of our Graphitized Petroleum Coke ensures stable feeding and predictable performance across diverse metallurgical processes. Each batch of GPC is tested for carbon content, sulfur, particle uniformity, and moisture, with customizable sizes available based on specific furnace requirements.
