Ferrosilicon 75 High Silicon Efficiency FeSi 75 Alloy for Fast Dissolution and Stable Silicon Recovery in Steelmaking

In alloy steel production and secondary refining, silicon serves as both a deoxidizer and critical alloying element. Steelmakers commonly face these operational challenges:

• Silicon yield loss due to oxidation during tapping
• Inaccurate silicon adjustment in high-grade alloy steels
• Slow melting or excessive fines causing slag instability
• Repeated alloy correction increasing costs and heat time

Silicon Iron Ferrosilicon 75 (FeSi 75) is engineered specifically for applications requiring high silicon efficiency, fast dissolution, and predictable metallurgical response.

With silicon content of approximately 75%, Ferrosilicon 75 delivers:

• Strong and rapid deoxidation performance
• Higher effective silicon yield per ton
• Reduced total alloy addition volume
• Improved cleanliness in alloy and special steels

This makes FeSi 75 the preferred choice for bearing steel, spring steel, stainless precursors, and low-oxygen steel grades.

Typical FeSi 75 Specification for Steelmaking and Foundry Applications

Available in 10–50mm and 10–100mm sizes:

• 10–50mm FeSi 75 granules - Fast and uniform melting, suitable for ladle metallurgy and induction furnaces
• 10–100mm FeSi 75 lumps - Stable melting in EAF and BOF operations, reduced oxidation loss during charging

Precise sizing improves silicon recovery efficiency and minimizes unreacted residues.

• Final deoxidation during tapping
• Silicon trimming in alloy and special steels
• Support for clean steel and inclusion control

• Graphitization promoter in gray iron
• Improved melt fluidity and casting quality
• Stable silicon input for ductile iron melts

• Silicon source for specialty alloys
• Reducing agent in metallurgical reactions
• Raw material for silicon-based industrial processes
