This carburizer boasts high-purity carbon composition with minimal harmful impurities, which helps eliminate common casting defects like porosity and inclusions in ductile iron, greatly enhancing casting density and surface finish. Thanks to complete high-temperature graphitization, its carbon structure is stable and active, dissolving and spreading quickly in molten iron. This ensures fast and consistent carburizing effect with even carbon distribution across the casting, effectively avoiding component segregation and stabilizing the mechanical performance of finished ductile iron parts. In actual casting production, the material features excellent high-temperature oxidation resistance and low burnout loss. It maintains steady carbon equivalent control during smelting, reduces production instability, and helps foundries cut overall production and scrapping costs.

Manufactured through professional high-temperature graphitization craftsmanship and strict multi-round quality inspection, this GPC carburizer is tailored for high-standard ductile iron casting. The product features ultra-high purity and negligible harmful impurities, with stable quality across all batches. It fully complies with the strict material requirements of high-end ductile iron production. We can adjust the particle specifications flexibly according to customers' smelting equipment and on-site production conditions to match diverse casting processes.

Adopting this graphitized petroleum coke carburizer in ductile iron production effectively facilitates graphite nucleation and uniform growth, restrains casting chill tendency, and optimizes internal graphite morphology. It comprehensively upgrades the toughness, tensile strength and fatigue resistance of ductile iron products. Compatible with mainstream smelting methods including electric furnace and cupola, it fits all conventional ductile iron grades. Long-term application helps enterprises reduce defective rate, improve overall production efficiency, and guarantee stable and reliable quality of finished castings.
