Ricarburante (antracite calcinata)

CAC

Calcined anthracite carbon raiser (CAC) is a thermally treated anthracite recarburizer that raises the carbon level of molten iron and steel. Calcination drives off volatiles and orders the carbon structure, so fixed carbon dissolves into the melt and lifts final C toward target chemistry without the cost of graphitized grades. With F.C 90-95% and a graphite-poor structure, recovery sits below synthetic graphite — which is precisely why it serves as an economical bulk carbon tier where premium pickup is not required. Typical use: grey and ductile iron carburization, casting recarburization, and EAF charge carbon for construction steel, dosed roughly 0.5-2.0 wt% depending on charge carbon deficit and target grade. The spec set supports controlled, low-residual additions: S ≤ 0.3% protects nodularity, Ash ≤ 4%, V.M ≤ 1.0%, Moisture ≤ 1.0%, N ≤ 300 ppm to limit pinholing, sized 1-5 mm for steady dissolution. Supplied with COA and MTC, multi-regional sourcing, ex Gebze bonded stock or CIF Marmara, 20 MT FCL. Send target chemistry and tonnage for an RFQ.
