Product Introduction
Ferrosilicon (FeSi) is smelted continuously in an open or semi-closed reduction furnace using semi-coke, silica, steel scrap and other products as raw materials. The appearance of FeSi is silver-gray, with metallic luster, and can be processed into ferrosilicon alloy powder, ferrosilicon block and FeSi granule according to customer requirements. Ferrosilicon is mainly used as deoxidizer and alloying agent for steelmaking, inoculant and nodularizer for cast iron, and it is also widely used in magnesium metal and chemical industry.
Ferrosilicon (Ferrosilicon) is an important ferroalloy composed of silicon (Si) and iron (Fe). It is usually made by high-temperature reduction in an electric arc furnace with quartz (SiO2) and steel as the main raw materials. The silicon content in ferrosilicon is generally 15%~90%. The most commonly used grades in industry are ferrosilicon 75% (FeSi75), ferrosilicon 72% (FeSi72) and ferrosilicon 65% (FeSi65).
Ferrosilicon has a wide range of uses in steelmaking, casting and other alloy production processes. It is a deoxidizer, alloying agent and reducing agent in the steel industry.

Key Features & Benefits
✅ Excellent deoxidation performance
Silicon reacts with oxygen to form stable silicon dioxide (SiO2), which can effectively remove oxygen from molten steel, improve the purity of steel, and enhance the performance of steel.
✅ Improve mechanical properties
Ferrosilicon can improve the strength, hardness and elastic modulus of steel, improve its wear resistance and impact resistance, and is widely used in high-performance materials such as structural steel and high-strength steel.
✅ Promote graphitization and improve casting quality
In the production of gray cast iron and ductile iron, ferrosilicon can be used as an inoculant to promote graphite nucleation, reduce white cast iron varieties, and improve casting structure and performance.
✅ High temperature resistance and corrosion resistance
Silicon has good **anti-oxidation and corrosion resistance, especially suitable for heat-resistant steel, stainless steel and other materials used in high temperature environments.
✅ Various specifications and strong equipment
The products provide various particle sizes from 0-3mm to 10-100mm**, which are suitable for different feeding methods and smelting processes, and can also be customized according to customer needs.
