Products Description
Ferro silicon72 compared with ferrosilicon 75, although they have different silicon content, their main use is similar, that is, as a deoxidizer in the steelmaking industry. In the process of steelmaking, ferrosilicon reacts with oxygen in molten steel to generate silica, thus playing the role of deoxidation.At the same time, as the heat released during the reaction helps to increase the temperature of the molten steel.

1.Another feature of ferro silicon 72 is that it is not only used as a deoxidizer in the steelmaking industry, but also has a wide range of applications in aluminum plants due to its low hardness. This is different from 75 ferro silicon, which is often regarded as hard 75 ferrosilicon and is mainly used as a deoxidizer in the steelmaking industry. In summary, Ferro silicon 72 is special because of its moderate silicon content and wide range of applications, which can be used as a deoxidizer in the steelmaking industry and also has important applications in aluminum plants, showing its importance and diversity in industrial applications.The special uses of ferrosilicon 72 mainly include: alloying element additives: as an alloying element additive, ferrosilicon 72 is widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel and other varieties. It is able to improve the properties of steel, such as hardness, wear resistance, and corrosion resistance.
