Product Introduction
Ferrosilicon is an alloy of iron and silicon, often abbreviated as fe si. Ferrosilicon is an iron-silicon alloy smelted in an electric furnace using coke, steel shavings, and quartz (or silicon dioxide) as raw materials.
Since silicon and oxygen are easily combined to form silica, silicon iron is often used as a deoxidizer in steelmaking, and as a reducing agent in ferroalloy production and the chemical industry. In the steelmaking industry, about 3-5kg of 75% ferrosilicon is consumed to produce one ton of steel. At the same time, ferro silicium can be used as an alloying element additive, widely used in low alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel, etc.
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.
Application
for the preparation of alloys:
As a reducing agent, ferrosilicon can reduce metal oxides in the smelting process, reduce the oxides to metals, and release a large amount of heat energy to improve the smelting efficiency.
Adding ferrosilicon can increase the mechanical properties of the alloy such as hardness, corrosion resistance and wear resistance, improve the strength and toughness of the alloy, and improve the purity and quality of the steel.
For Casting:
In the casting process, adding ferrosilicon can increase the hardness of the casting, and the corrosion resistance can enhance the wear resistance of the casting. Especially for components that need to withstand high-speed friction and heavy loads, such as engine cylinder liners, cylinder heads, etc., the addition of ferrosilicon can effectively prolong their service life.
Improve the mechanical strength and toughness of castings, control the shrinkage and shrinkage defects of castings, and increase the quality and performance of castings by adding ferrosilicon reasonably to meet the needs of different engineering applications.
Used to make High grade steel：
In the process of steelmaking, ferro silicium is often used as a deoxidizer, alloying agent, carbon content regulator, and inclusion reducer.
Reasonable addition of ferro silicio can improve the composition and performance of steel, improve the quality of steel and the applicability of engineering applications
