Ferro Silicon Alloy 75% for Steel Refining Deoxidation and Silicon Content Adjustment

Refining is where a heat's composition is finalized, and the silicon trim must land inside a narrow window on the first attempt. ZHENAN FeSi 75 is the addition melt shops rely on at that stage: dense, fast-dissolving, and analysed batch by batch so the silicon credit on the certificate matches the credit delivered to the ladle. Aluminium discipline is critical at this step, so the standard grade is held to Al ≤1.5%, while a ≤0.5% low-Al line covers clean-steel programs. The material ships as lump (10–50 mm / 50–100 mm) or as crushed fractions (0–3 mm / 3–10 mm) for automatic metered feeding. With 2,000 MT of monthly capacity behind the order book, refining-stage supply can run on rolling monthly contracts instead of spot purchases.

Produced under the ZHENAN name by Zhenan Metallurgy Co., Ltd in Anyang, Henan, China, this ISO 9001 certified supply is listed as model FeSi 75, with refined sizing available on request. Batch traceability runs from furnace release through to shipment papers — exactly what refining-stage audits require.

Refining lots are released against the limits above; the low-Al line covers tight aluminium specifications.

• Lump at 10–50 mm and 50–100 mm; crushed 0–3 mm and 3–10 mm fractions for metered feeding, with sieve report attached.
• One certificate per batch; composition and sizing adjustable to the customer's window.

• Final kill of dissolved oxygen before casting; slag-metal oxygen control through the refining hold.
• Trimming the melt into the grade's silicon window with a single, predictable addition.
• Clean and special steels: the low-Al line keeps aluminium pickup inside tight ceilings.
• Automatic feeding: crushed fractions meter cleanly into wire feed and injection systems.
• Rolling supply programs scheduled against monthly refining consumption.

A refining addition program is ordered on five confirmations:

• Volume and schedule — no fixed MOQ; contracts roll monthly within the 2,000 MT capacity.
• Quotation basis — FOB, CFR or CIF.
• Packing — jumbo bags, or 20/25/50 kg units for shop handling.
• Papers — mill test report and batch COA; SGS or BV inspection on request.
• Dispatch and settlement — 5–10 working days after payment, by L/C, T/T or Western Union.

To receive an accurate quotation, please provide the following details:

1. Refined grades and the silicon window being trimmed into;
2. The aluminium ceiling written in your specification;
3. Feeding form — lump, or crushed fractions for the metering system;
4. Monthly tonnage plus the destination port.
