Ferrosilicon 72% Lump and Granules for Steel Mills Foundries and Cast Iron Manufacturing

FeSi 72 is the volume grade — the balanced ferrosilicon that mills and foundries consume by the container — and ZHENAN supplies it in both forms from one grade stream. The chemistry never changes between the two: Si ≥72%, Al ≤2.0%, C ≤0.2%, P ≤0.04%, S ≤0.02%. What changes is the sizing, and sizing is a process decision: lump at 10–50 mm and 50–100 mm drops cleanly into furnace and ladle charging, while granules at 0–3 mm and 3–10 mm feed foundry treatment and metered addition systems without further crushing on your floor. Works that run a melt shop and a casting line can take both forms in one container — separate packing, separate batch papers, one purchase order — giving purchasing a single negotiation and logistics one stream to manage.

Zhenan Metallurgy Co., Ltd makes this grade under the ZHENAN mark. The works sits in Anyang, Henan, and carries ISO 9001 across melting, crushing and sieving. Both physical forms of FeSi 72 — lump and granules — leave the same furnace line, the same quality lab and the same stockyard.

Volume buyers get volume logistics: form-split containers, per-form papers and consolidated dispatch out of one Anyang stock.

One chemistry governs both sizings; the ceilings above travel with every FeSi 72 release, whatever the form.

• Lump carried at 10–50 mm and 50–100 mm; bespoke crushing possible.
• Granules at 0–3 mm and 3–10 mm; finer splits on demand.
• Each form is batch-analysed on its own, and granule certificates carry the sieve data; papers align with GB/T 2272 PG FeSi72Al2.0.

• Mill deoxidation and alloying where the 72 grade's cost-to-silicon balance fits the melting program.
• Foundry inoculation across gray and ductile iron production.
• Cast iron manufacturing: base iron silicon adjustment and graphitization support.
• Metered processes: granule feeding wherever lump handling is impractical.
• Ferroalloy production: reductant and silicon source duties.

• The form split — lump, granules, or both — and the tonnage behind each.
• Size windows per form: lump 10–50 mm or 50–100 mm; granules 0–3 mm or 3–10 mm.
• Documents: per-form certificate of analysis (granules with sieve report); SGS or BV if required.
• Packing: jumbo bags for bulk, 25 kg moisture-proof bags for granules in humid climates.
• Commercial footing: no fixed MOQ; FOB / CFR / CIF; shipment 5–10 working days after payment; L/C, T/T, or Western Union; 2,000 MT monthly capacity.
