Ferro Silicon FeSi 75% for Cast Iron Inoculation Steel Production and Metallurgical Processing

Most ferro silicon grades serve a single audience; FeSi 75 earns its place across several. In the foundry it inoculates — promoting graphitization, preventing chill, and helping ductile iron develop its nodules after magnesium treatment. In the steel shop it deoxidizes the melt and alloys silicon into the target grade window. Across the wider metallurgical plant it acts as the silicon carrier for pre-alloys and general processing duty.

ZHENAN supplies this crossover grade in the form each shop needs — lump at 10–50 mm or 50–100 mm for melting and steelmaking, and screened granules at 0–3 mm or 3–10 mm for foundry treatment — with one specification behind both forms: Si ≥75%, Al ≤1.5% (low-Al line ≤0.5%), C ≤0.2%, P ≤0.04%, S ≤0.02%. Each batch is analysed before release and each form receives its own certificate, so the casting line and the melt shop see the same trusted composition in the shape each of them feeds.

ZHENAN is the brand of ZhenAn International Co., Limited. The works is located in Anyang, Henan, China, and operates under an ISO 9001 certified quality system. This crossover supply is listed as model FeSi 75, available in lump and in granules. Both forms draw from the same analysed heat lots, so a dual-form order still carries one consistent chemistry.

The crossover specification carries identical limits whether a lot leaves as lump or as screened granules.

• Lump: 10–50 mm or 50–100 mm. Granules: 0–3 mm or 3–10 mm, with finer cuts available on demand.
• Every batch is certified; granule lots carry their sieve results.

• Gray iron inoculation: graphitization, chill prevention and machinability stability.
• Ductile iron: nodule development support alongside the spheroidizing treatment.
• Steel production: deoxidation of the melt and silicon alloying to the target window.
• Base iron adjustment ahead of treatment.
• Pre-alloy production and general metallurgical carrier duties.

• Order floor: none fixed — quotations follow the shape of your program.
• Pricing: FOB, CFR or CIF.
• Packing: 1 MT jumbo bags, or 25 kg moisture-proof bags for the foundry line.
• Dispatch: 5–10 working days from payment.
• Settlement: L/C, T/T, Western Union.
• Capacity behind the order: 2,000 MT monthly.
• Papers: certificate of analysis per batch and form.
• Inspection: SGS or BV when required.

To prepare an accurate quotation, please share the following details:

1. Which shops the material serves — steel shop, foundry, or both — and the form each needs.
2. Size window per form (lump 10–50 mm or 50–100 mm; granules 0–3 mm or 3–10 mm).
3. Standard or low-Al (≤0.5%) material.
4. Monthly tonnage, destination port and packing preference.
