Introduction to ferro silicon

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.

Properties of ferrosilicon

The silicon content in ferrosilicon is generally between 40% and 70%, which has a relatively high silicon content.

Ferrosilicon has a low iron content compared to other ferroalloys, typically between 15% and 30%.

The high silicon content and low iron content of ferrosilicon make it have good oxidation resistance and can be used at high temperature for a long time.

Ferrosilicon has good deoxidation performance, which can effectively remove oxides and impurities in molten steel.

Ferrosilicon is not easy to decompose and oxidize at high temperature, and has good stability.

The ferrosilicon provided by the ferro silicon supplier has good deoxidation performance and can effectively remove oxides and impurities in molten steel.

Ferrosilicon has a low coefficient of thermal expansion and can maintain a stable shape and size at high temperatures.

What projects can Ferro Silicon provide services for?

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.

Choosing the Optimal Ferro Silicon for Your Alloy

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.

Choosing the Best ferro silicon for Your Casting

Used to make high-purity ferro silicon:

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
