Premium Ferrosilicon FeSi 75 High Silicon Iron Alloy with 75% Silicon Content

In modern steel production, high-purity silicon addition is critical for both deoxidation and alloying. Common operational issues include:

• Silicon yield loss due to oxidation and fines
• Inconsistent silicon addition affecting alloy steel quality
• Variable melt behavior in foundry iron and ductile castings
• Re-alloying and cost increases from poor silicon control

Premium Ferrosilicon FeSi 75 from ZhenAn addresses these challenges by offering high silicon content, controlled particle size, and industrial-grade consistency, ensuring reliable steelmaking and metallurgical performance.

• Silicon (Si): approx. 75%
• Fast melting and high recovery efficiency
• Ideal for stainless steel, alloy steel, and low-oxygen steel grades
• Supports inclusion control and clean steel production

• Secondary metallurgy and ladle treatment
