Ferrosilicon - Introduction

Ferrosilicon is an alloy made of a certain proportion of silicon and iron. It has some unique properties such as high hardness, high melting point, high permeability and good corrosion resistance.

Ferrosilicon is widely used in industry. One of the most common uses is as a deoxidizer and alloy additive in the metallurgical industry. Ferrosilicon can remove oxygen in the steel manufacturing process, thereby reducing the content of impurities in the steel and improving the quality of the steel. In addition, ferrosilicon is also commonly used in the manufacture of cast iron, stainless steel, silicon steel, power transformer core and so on.

Ferrosilicon can be prepared by two basic methods: smelting and corrosion. The smelting process is to smelting silicon ore with high purity smelting iron ore to obtain ferrosilicon alloy. Molten corrosion method is to melt high purity silicon and pure iron together, and then cooling solidification, to obtain iron silicon.

When using ferrosilicon, you need to pay attention to the following safety information. Ferrosilicon releases toxic hydrogen when in contact with water and acid, so contact with water or acid should be avoided. In addition, ferrosilicon is also easily oxidized, and it is necessary to avoid exposure to air when storing or using. If you come into contact with ferrosilicon, use appropriate protective measures, such as wearing gloves and goggles.
