Frequently Asked Questions
What is the typical FeSiMn dosage for EAF?
0.5-1.2 wt% FeSiMn for EAF deoxidation + alloying (targeting bath Mn 0.5-1.0%). For large EAFs such as Tosyalı/Çolakoğlu/İÇDAŞ, typical monthly consumption is 400-800 tons. Dosage decided by the line metallurgy chief.
When I receive Mn ≥62% spec, what should the actual COA show?
Arsam canonical spec: Mn 65-72%, Si 14-22%, C ≤2.0%, P ≤0.20%, S ≤0.03%. COA + MTC + radiation certificate per lot. SGS/BV inspection option standard for MENA customers such as Hadeed/Ezz.
FeSiMn vs separate FeMn + FeSi — which is more cost-effective?
A single FeSiMn lot for combined EAF deoxidation + alloying delivers approximately $5-8 per ton cost advantage (vs. separate FeMn + FeSi). Plus, a single container = logistics + handling savings. Separate use only for specific metallurgical discipline.
What is the FeSiMn lot delivery time?
Chinese FOB Tianjin → CIF Mersin/İskenderun 28-35 days. Iranian source alternative via Bandar Abbas → road/ferry 12-21 days. Dubai bonded warehouse for MENA customers 3-5 days. Turkish EAFs (Tosyalı/Çolakoğlu) prefer tender-based annual frame contracts.
