Introduction to Ferro Silicon 75

Ferro Silicon 75 (FeSi75) is a ferroalloy containing about 75% silicon. It is produced by reducing iron ore and silicon ore in an electric arc furnace. This alloy is widely used in the iron and steel industry and foundry industry, and is popular for its superior properties and versatile applications.

Main Composition
Silicon (Si): approx. 75
Iron (Fe): balance
Impurities: aluminum, calcium, carbon, phosphorus, sulfur, etc.
Main uses of Ferrosilicon 75
Deoxidizer:
Ferrosilicon 75 is used as an effective deoxidizer in the steel smelting process. Due to its high silicon content, it can effectively remove the oxygen in the liquid steel and improve the quality and performance of steel.

Alloying agent:
Ferro Silicon 75 is also used as an alloying agent, added to steel to improve its mechanical properties and corrosion resistance. Especially in the production of silicon steel, spring steel, stainless steel and other special steel grades, ferrosilicon 75 is an essential additive.

Inoculant:
Ferrosilicon 75 is used as an inoculant in the production of cast iron, which can promote the formation of graphite morphology and thus improve the mechanical properties of cast iron.

Refractories:
Ferrosilicon 75 is also used in the manufacture of refractory materials and in the ceramic industry, where it is widely used in a variety of high-temperature industrial applications due to its high melting point and good heat resistance.

Production process of Ferrosilicon 75
The production of ferrosilicon 75 is mainly carried out through the electric arc furnace smelting process. Raw materials include silica, coke and steel chips. Under high temperature conditions, silica reacts with coke to produce ferrosilicon alloy, while releasing carbon monoxide gas. The production process requires control of temperature, reaction time and raw material ratios to ensure the purity and quality of the alloy.

Market Prospects
As the global steel industry continues to grow, so does the demand for ferrosilicon 75. Especially in emerging markets such as China and India, the growth in steel production is driving the demand for ferrosilicon 75. In the future, the ferrosilicon 75 market will continue to grow steadily with a promising market outlook.

Conclusion
Ferrosilicon 75, as an important ferroalloy, has a wide range of applications in the steel smelting and foundry industry. Its excellent deoxidizing, alloying and pregnant properties make ferrosilicon 75 play an important role in improving the quality of iron and steel and improving the performance of cast iron. With the continuous development of the iron and steel industry, the market demand for ferrosilicon 75 will also continue to grow.
