Ferro silicon's usage

First, it is used as a deoxidizer. It uses oxygen blowing or adding oxidants to decarburize molten iron and remove harmful impurities such as phosphorus and sulfur.

In the process of smelting pig iron into steel, the oxygen content in the molten steel gradually increases and exists in the molten steel in the form of FeO. If the oxygen in the steel is not removed, the mechanical properties of the cast steel billet are not good.

It can also be used as an alloying agent. Alloying elements can not only reduce the impurity content in steel, but also adjust the chemical composition of steel. Commonly used alloying elements include silicon, manganese, chromium, molybdenum, vanadium, titanium, tungsten, cobalt, boron, niobium, etc. Steels containing different alloying elements and alloying contents have different characteristics and uses.

Silicon can significantly improve the elasticity and magnetic conductivity of steel. Manganese can reduce the brittleness of steel, improve the hot working properties of steel, and improve the strength, hardness and wear resistance of steel. Manganese is an indispensable functional basic raw material for the production of high-quality steel.

It can remove impurities such as sulfur and oxygen during the steelmaking process, and improve the physical properties of steel by improving properties such as strength, hardness and wear resistance. At present, there is no other element that can replace the role of manganese in the steel production process.
