Products Description
Silicon is a semi-metallic element with good thermal and chemical stability, while iron is a common metallic element with good electrical and thermal conductivity. When the two are combined to form ferro silicon, these properties are fused and improved, which makes ferro silicon have unique application value in metallurgy, chemical industry and other fields. Therefore, it is known that ferro silicon is an alloy composed of iron and silicon, in which the content of silicon is usually between 15% and 90%. It has high density, high hardness and high melting point, and it can remain stable at high temperature. Ferro silicon is widely used in industry because of its high silicon content and special physical and chemical properties.
The working principle of ferro silicon is mainly based on its chemical properties. In the smelting process, ferro silicon can be used as a reducing agent to reduce other metal oxides to metals. In addition, ferro silicon can also be used as an alloy additive to improve the properties of metal materials, such as increasing strength and improving corrosion resistance. In metallurgical industry, ferro silicon is often used as deoxidizer in steelmaking, which can remove oxygen and other impurities in steel and improve the purity and quality of steel. In addition, ferro silicon can also be used as an inoculant in foundry industry to promote metal crystallization and improve the strength and wear resistance of castings. In the chemical field, ferro silicon can be used as the carrier of catalyst to improve its activity and stability.
Ferro silicon is most used in steelmaking, foundry and ferro alloy industries. They consume more than 90% of ferro silicon. Among various brands of ferro silicon, 75% ferro silicon is the most widely used at present. In conclusion, ferro silicon is widely used in metallurgy, chemical industry, electronics and other fields.
