ZhenAn – 30 Years of Metallurgical Expertise in Ferrosilicon Supply
In steel manufacturing, deoxidation and alloying are no longer optional—they are essential for producing high-strength, low-impurity steels. Ferrosilicon (FeSi) is a high-performance ferroalloy that addresses key metallurgical challenges:
Effective deoxidation: FeSi reacts with dissolved oxygen in molten steel, minimizing porosity and preventing blowholes.
Alloying precision: High silicon content (up to 90%) enables precise adjustment of steel properties for rebar, structural, and specialty steels.
Inclusion control: Ferrosilicon helps refine microstructure, reduce non-metallic inclusions, and improve surface quality of steel.
We offer FeSi designed for professional steel and alloy production, with precise control over silicon content, particle size, and chemical purity.
| Grade | Si Content | Particle Size | Application | Key Benefits |
|---|---|---|---|---|
| FeSi 75 | 75% ±2% | 10–50 mm | Electric Arc Furnace (EAF), converter steel | Cost-effective deoxidation, stable silicon addition |
| FeSi 80 | 80% ±2% | 10–100 mm | Stainless steel, high-strength steel | High silicon purity, low tramp elements |
| FeSi 90 | 90% ±2% | 5–50 mm | Specialty steel, alloy production | Maximum silicon content, improved mechanical properties |
Ferrosilicon is classified as a ferroalloy because it contributes silicon as an alloying element while also improving steel properties. While it can be seen as a metallurgical additive for oxygen control, its role in strengthening and modifying steel makes it indispensable in professional alloy design.
Ferroalloy function: Directly alters the chemical composition of steel.
Metallurgical additive function: Controls oxygen levels, prevents defects, and stabilizes microstructure.
Electric Arc Furnace (EAF) Steelmaking – FeSi 75–80 for bulk deoxidation and alloying.
Converter Steel Production – High-purity FeSi 80–90 ensures uniform silicon addition and low impurity levels.
Stainless Steel and Specialty Alloys – FeSi 90 for precise alloying and enhanced corrosion resistance.
Foundry and Cast Iron – Improves hardness, wear resistance, and reduces casting defects.
When sourcing FeSi, professionals consider:
Silicon content (%) – Determines deoxidation efficiency and alloying effect.
Particle size (mm) – Influences melting rate and uniformity in molten steel.
Impurities (Al, Ca, Mg, P) – Critical for specialty steels requiring clean chemistry.
Consistency across batches – Ensures predictable mechanical and chemical properties.
ZhenAn advantage: Our FeSi undergoes rigorous quality control, including chemical analysis and size distribution testing, guaranteeing repeatable performance in demanding metallurgical applications.
