Standard Grade FeSi75 Ferrosilicon Iron Alloy

Standard Grade FeSi75 Ferrosilicon Iron Alloy is produced by melting high-purity silica and iron materials in an electric furnace. The resulting alloy provides a controlled silicon level of around 75%, making it a reliable and versatile material for a range of steelmaking processes.

FeSi75 serves two major functions: oxygen removal and silicon alloying. During steel refining, the alloy reacts quickly with dissolved oxygen, reducing inclusions and contributing to a cleaner metal bath. Its stable composition supports consistent alloying behavior, enabling manufacturers to adjust silicon content precisely according to different steel specifications.

This standard-grade ferroalloy is suitable for general steel production, structural steel, and casting formulations. It enhances fluidity in molten metal, improves heat resistance, and increases strength in finished steel products. Because of its predictable melting characteristics, FeSi75 integrates smoothly into basic oxygen furnaces (BOF), electric arc furnaces (EAF), and a wide range of induction furnace operations.

Each batch is tested for silicon percentage, aluminum levels, carbon content, and granule uniformity to ensure dependable metallurgical performance. The material is offered in various particle sizes to match different furnace charging systems and process requirements.
