Metallurgical Product Description
Ferrosilicon is an iron alloy composed of iron and silicon. Ferrosilicon is an iron-silicon alloy made from coke, steel scraps, quartz (or silica) as raw materials and smelted in an electric furnace.

Manufacture And Use
Ferrosilicon is widely used in the steel industry, foundry industry and other industrial production. Ferrosilicon is widely used in steelmaking processes, casting processes and other industrial production processes. The reason why this ferroalloy is widely used by manufacturers is mainly because ferrosilicon plays a deoxidizing role in the smelting process. The better the deoxidation, the better it is made. The better the quality of the steel.
In addition, the silicon content in ferrosilicon is also different, so manufacturers often distinguish them by numbers. For example, the silicon content of ferrosilicon 75 is roughly between 70-80. Adding silicon during the steelmaking process can affect the strength and strength of the finished steel. Hardness and elasticity play a reinforcing role, increasing the magnetic permeability of steel and reducing the hysteresis loss of transformer steel.
The role of ferrosilicon
1. Used as deoxidizer and alloying agent in steelmaking industry.
2. Used as inoculant and spheroidizing agent in the cast iron industry.
3. Used as reducing agent in ferroalloy production.
4. Used for high-temperature smelting of metallic magnesium in Pidgeon process magnesium smelting.
5. Used as suspended phase in the mineral processing industry, used as welding rod coating in the welding rod manufacturing industry, and used in the chemical industry to manufacture silicone and other products.
