Ferrosilicon Lump FeSi 75% for Steelmaking Deoxidizer and Silicon Alloy Addition

Every kilogram of ferrosilicon charged does two jobs at once: it kills oxygen and it lifts silicon. ZHENAN FeSi 75 lump is specified so that both jobs stay predictable. As a deoxidizer, its silicon binds dissolved oxygen into silica that reports to the slag; as an alloy addition, the same charge builds the silicon residual toward the grade window, so no second addition is needed. The material carries Si ≥75% with aluminium held to ≤1.5% (a ≤0.5% low-Al line exists for aluminium-sensitive grades), broken to 10–50 mm for ladle and induction charging or 50–100 mm for furnace work, and documented batch by batch. For a melt shop that wants to dose on schedule and trust the analysis, this is the deoxidizer grade to standardize on.

• Brand: ZHENAN — Zhenan Metallurgy Co., Ltd
• Origin: Anyang, Henan Province, China
• Certification: ISO 9001
• Model: FeSi 75 lump (deoxidizer grade)
• Handling: Deoxidizer lots are kept apart from foundry splits to protect the low-Al option

One grade, one set of numbers — the deoxidizer line holds these limits on every release.

• On-the-shelf windows: 10–50 mm and 50–100 mm; bespoke cuts on request.
• Low-Al line available at Al ≤0.5%.
• Reference family GB/T 2272 PG FeSi75Al1.5; the batch certificate rides along with the delivery.

• Precipitating deoxidation in furnace and ladle; diffusion practice when conditioning the slag.
• Building the silicon residual in structural, spring, bearing, heat-resistant and silicon electrical steels.
• The silica reaction releases heat, helping the melt hold temperature through the kill.
• Reductant work in low-carbon ferroalloy production.
• Foundry crossover: silicon addition and inoculation support in iron works.

Include the following details in your inquiry so we can quote accurately:

• The steel grades this deoxidizer serves;
• Whether the aluminium ceiling is 1.5% or the 0.5% low-Al line;
• The lump window your charging gear takes;
• Port of discharge and volume per shipment.
