Operational Value & Buyer Pain Points Solved
1. Maximized Carbon Absorption & Lower Energy Consumption
Low volatile matter ( ≤0.5%) eliminates gas pickup during ladling and ensures rapid dissolution in liquid iron/steel. This directly reduces tap-to-tap times and furnace electrical load.
2. Strict Sieving Control = Less Dust Loss
Fines (<0.5 mm) in CPC often burn off instantly on the bath surface without dissolving. We use multi-deck mechanical screening to enforce a strict <5% fines limit, ensuring every bag paid for makes it into the melt.
3. Reliable Sulfur & Ash Control for Refractory Protection
With ash constrained under 0.5%, slag volumes remain low. This prolongs crucible and refractory lining lifespan by reducing chemical erosion in induction furnaces.

FAQ
Q: Is FC 98% CPC a direct substitute for Graphite Petroleum Coke (GPC)?
A: Not in all cases. While CPC delivers lower cost-per-carbon in general steelmaking and gray iron, high-end ductile iron foundries requiring extreme low sulfur (≤0.05%) and rapid graphitization should utilize GPC. For general recarburization where sulfur budget permits up to 0.5%, our Low-S CPC provides a 20%-30% raw material cost savings.
Q: .What is the typical shelf life and storage requirement for calcined petroleum coke?
A: CPC is chemically inert and does not degrade over time. If kept in dry, covered conditions away from direct open flames or strong oxidizing agents, the material maintains its specification indefinitely. We recommend storing jumbo bags on elevated pallets in covered warehouses to prevent ambient moisture absorption from standing water.
