Frequently Asked Questions
What is the difference between Arsam FeSi 75 and Iranian-sourced 70-72%?
Chinese FeSi 75% (Si 72-78%, Al ≤1.5%) is standard EAF deoxidation. Iranian-sourced 70-72% grade fits grey iron + certain foundry inoculation applications — spec verification and line dosage calibration with Sinan technical support.
What should the FeSi dosage be for grey iron deoxidation?
Typical 0.3-0.6 wt% FeSi 75% (targeting bath Si 1.5-2.5%). For a 12 MT lot, approximately 50-72 kg FeSi. The foundry line metallurgy chief decides — for medium-to-large lines such as Componenta, Sinan shares the dosage calculation template.
When is FeSi preferred over SiC as an inoculant?
FeSi 75 (Si 75%, Al ≤1.5%) for deoxidation + final inoculation only. If carbon demand + graphite nodularization matter, SiC (C 75-80%, Si 18-20%) is preferred. Most Turkish foundries use both at different stages.
What is the FeSi shipment lead time for TR foundries?
Chinese source FOB Tianjin → CIF Gemlik 28-35 day logistics. If stock is available at the Gebze bonded warehouse, 24-48 hour rush delivery. For Iranian source, Bandar Abbas → road/ferry route 12-21 days.
