Also known as: Calcined petroleum coke · CPC carbon raiser
Calcined Petroleum Coke (CPC) is a carbon raiser used to set and correct carbon content in molten iron and steel. Calcination drives off volatiles and orders the carbon structure, yielding a dense material with ≥ 98.5% fixed carbon, ≤ 0.5% S, ≤ 0.5% ash and ≤ 0.7% V.M. Dissolved in the melt, that carbon raises the C level and feeds graphite nucleation, which governs strength and machinability in cast iron. Foundries pouring grey and ductile iron use it for carbon adjustment heat after heat, and EAF mills recarburize the charge and run it as part of slag-foaming carbon practice. Typical additions run roughly 0.5-2.0 wt% in cast iron, with charge-level dosing in steelmaking, tuned to bath temperature and target C. The 1-5 mm sizing supports steady dissolution and high recovery with low fume. Low sulphur protects nodularity in ductile grades and limits desulphurization load. Each lot ships with COA. Multi-regional sourcing supports CIF Marmara delivery and Gebze bonded stock, 20 MT FCL. Send your grade and tonnage for an RFQ.
