In modern steelmaking and alloy production, silicon yield instability remains a critical cost and quality risk. Common issues faced by mills and foundries include:
Ferrosilicon FeSi 75 / FeSi 65 is engineered to address these challenges by delivering stable silicon content, controlled particle size, and reliable melting behavior across different furnace types.
Using the correct FeSi 75 or FeSi 65 grade reduces over-addition and stabilizes downstream chemistry control.
| Element | FeSi 75 (%) | FeSi 65 (%) |
|---|---|---|
| Silicon (Si) | 74.0–80.0 | 63.0–68.0 |
| Iron (Fe) | Balance | Balance |
| Aluminum (Al) | ≤ 2.0 | ≤ 2.0 |
| Carbon (C) | ≤ 0.20 | ≤ 0.25 |
| Phosphorus (P) | ≤ 0.04 | ≤ 0.04 |
| Sulfur (S) | ≤ 0.02 | ≤ 0.02 |
Customized chemistry control is available for specific steel grades or furnace practices.
FeSi 75 / FeSi 65 Standard Sizes: 10–50mm & 10–100mm
Uniform sizing improves silicon recovery efficiency and minimizes slag instability.
ZhenAn produces FeSi 75 and FeSi 65 using submerged electric arc furnace smelting, combined with:
Post-smelting, all material undergoes crushing, screening, magnetic separation, and batch chemical analysis, ensuring suitability for continuous industrial use.
Each batch of Ferrosilicon FeSi 75 / FeSi 65 is evaluated for:
This approach helps steelmakers avoid process fluctuations, yield loss, and re-alloying costs.
Packaging is designed to minimize moisture exposure and oxidation during transport and storage.
ZhenAn supports buyers who value process reliability over short-term price fluctuations.
FeSi 75 offers higher silicon concentration and stronger deoxidation, while FeSi 65 provides a more economical solution for standard alloying and foundry use.
Both 10–50mm and 10–100mm are suitable. The choice depends on furnace capacity, charging method, and desired melting speed.
In some carbon steel applications, yes. However, high-precision alloy steels typically require FeSi 75 for accurate silicon control.
Yes. Both FeSi 75 and FeSi 65 support graphitization and melt consistency in ductile and gray iron.
ZhenAn can adjust silicon content, impurity limits, and particle size distribution to meet specific production requirements.
