Ferrosilicon 75/65 | High Purity FeSi for Steelmaking, Deoxidation & Alloy Production | 10–50mm Industrial Grade

In modern steelmaking, uncontrolled deoxidation or inconsistent alloying can lead to reduced steel quality, increased production costs, and inconsistent mechanical properties. Ferrosilicon 75/65 from ZhenAn provides a reliable solution for steelmakers, ensuring precise silicon content, high purity, and superior deoxidation efficiency. Produced under strict quality control, our industrial-grade FeSi 75/65 is ideal for deoxidizing steel, improving strength, and achieving consistent alloy composition.

Ferrosilicon 75/65 is a ferroalloy composed primarily of silicon (Si) and iron (Fe), specifically engineered for steelmaking and metallurgical applications. With a silicon content of 65-75%, this high-purity FeSi offers excellent performance for deoxidation and alloying, minimizing the risk of non-metallic inclusions in steel. Available in 10-50mm particle sizes, it is suitable for electric arc furnace (EAF), ladle metallurgy, and converter steelmaking processes.

• Steel Deoxidation: During steel production, dissolved oxygen can lead to defects such as blowholes, cracks, and non-uniform microstructure. FeSi 75/65 effectively removes oxygen by forming stable silicon oxides, ensuring clean steel with consistent mechanical properties.
• Alloying for High-Performance Steels: For low-alloy and high-strength steels, precise silicon content is critical. Adding Ferrosilicon 75/65 adjusts the silicon level, enhancing hardness, tensile strength, and corrosion resistance without compromising ductility.
• Foundry and Cast Iron Production: FeSi 75/65 improves fluidity and machinability of cast iron while refining grain structure, reducing defects, and optimizing surface finish.

• High Purity & Consistency - Silicon content tightly controlled within 65-75%, ensuring predictable performance.
• Optimized Particle Size (10-50mm) - Promotes fast dissolution in molten steel, reducing reaction time and energy consumption.
• Low Impurities - Minimal sulfur and phosphorus prevent negative impacts on steel properties.
• Industrial-Grade Reliability - Produced in electric arc furnaces using high-grade quartz and iron sources for uniform composition.
• 30+ Years of Expertise - ZhenAn has supplied ferroalloys worldwide, trusted by steel mills and alloy manufacturers for decades.
