| High Light | Industrial Grade Ferro Silicon Alloy ，10–220mm Granules FeSi 65/75 ，Steelmaking Deoxidation Silicon Iron | ||
In modern steelmaking and foundry operations, precise silicon addition is crucial to:
Achieve stable deoxidation and minimize oxygen-related defects
Maintain consistent alloy composition for high-grade steels
Improve graphitization and melt stability in ductile and gray iron
Reduce costs caused by re-alloying or process variability
FeSi 65/75 from ZhenAn delivers industrial-grade, high-purity silicon iron with controlled particle sizing, providing reliable performance for steel refining, alloying, and foundry operations.
Silicon (Si): approx. 65%
Moderate deoxidation power, suitable for carbon steel and low-alloy steel
Supports conventional foundry iron and ductile iron casting
Optimized for cost-effective and predictable furnace operation
Silicon (Si): approx. 75%
Strong deoxidizer for high-grade and alloy steels
Fast melting with high silicon recovery
Ideal for stainless steel, specialty alloys, and low-oxygen steel production
Selecting the correct FeSi grade ensures stable steel chemistry, optimized alloying, and consistent metallurgical results.
| Element | FeSi 65 (%) | FeSi 75 (%) |
|---|---|---|
| Silicon (Si) | 63.0–68.0 | 74.0–80.0 |
| Iron (Fe) | Balance | Balance |
| Aluminum (Al) | ≤ 2.0 | ≤ 2.0 |
| Carbon (C) | ≤ 0.25 | ≤ 0.20 |
| Phosphorus (P) | ≤ 0.04 | ≤ 0.04 |
| Sulfur (S) | ≤ 0.02 | ≤ 0.02 |
Composition can be customized based on steel grade, furnace type, or foundry requirements.
10–50mm – fine granules for ladle treatment and secondary metallurgy
10–100mm – standard granules for EAF, BOF, and foundry charging
10–220mm – coarse granules for bulk furnace addition and slower silicon release
Controlled particle sizes minimize fines, improve silicon recovery, and ensure uniform melting, supporting industrial consistency.
Primary and secondary deoxidation in carbon and alloy steels
Silicon adjustment for precise chemical control
Reduces inclusion formation and supports clean steel production
Promotes graphitization in gray and ductile iron
Stabilizes melt fluidity and improves casting surface quality
Provides consistent silicon input for repeatable foundry results
Base silicon source for specialty alloys
Reducing agent in metallurgical processes
Raw material for silicon-based chemical applications
ZhenAn produces FeSi 65/75 using submerged electric arc furnace smelting, combining:
High-purity quartz as silicon source
Low-impurity carbon reductants
Controlled smelting, tapping, and cooling parameters
Post-production includes crushing, grading, magnetic separation, and batch chemical verification, ensuring industrial-grade consistency and reliable silicon recovery.
Each batch undergoes rigorous QC:
Stable silicon content
Low phosphorus and sulfur
Controlled aluminum and carbon content
Uniform particle size distribution
This guarantees efficient furnace operation, optimized alloy use, and consistent metallurgical results.
1 MT jumbo bags
25 kg palletized bags
Bulk shipment for long-term industrial supply
Packaging protects against moisture and oxidation, maintaining FeSi 65/75 quality during storage and transport.
30+ years of ferroalloy manufacturing expertise
Specialized in steelmaking-grade, foundry-grade, and alloying FeSi
Flexible specifications and particle sizing
Reliable long-term industrial supply
ZhenAn partners with industrial buyers who require stable metallurgical performance, high silicon recovery, and consistent industrial-grade quality.
FeSi 65 provides moderate silicon content for standard alloy steel and cast iron, while FeSi 75 offers high silicon content, fast melting, and strong deoxidation for high-grade and specialty steels.
10–50mm fine granules are preferred for rapid and uniform dissolution, while 10–100mm granules are standard for bulk furnace charging.
Yes. Both grades improve graphitization, melt stability, and casting quality.
Through submerged electric arc furnace smelting, batch chemical verification, and precise particle sizing.
Yes. ZhenAn can adjust silicon content, impurity limits, and granule sizes to meet specific steel grades, furnace types, or metallurgical processes.
