Ferrosilicon In Steel Making & Casting

Ferrosilicon has a wide range of applications in steel making and casting, so manufacturers need to wholesale ferrosilicon on time to maintain normal operation. Ferrosilicon is rich in silicon, so it can be better used in the deoxidation process of steel making and to improve the ​​​​​​​inoculated effect in casting.

  1. Application of ferrosilicon in steelmaking

    Before steel making, the furnace needs to be filled with oxygen, so as to effectively raise the furnace temperature and provide a stable high temperature environment for steel making. In the later stage, the steel is filled with oxygen, which makes the steel more oxides and seriously affects the purity of the steel. The use of ferrosilicon can be a good treatment of oxygen in the steel, because it is rich in internal silicon elements, thus producing a chemical reaction with the oxygen in the steel to produce silicon dioxide gas, taking away most of the oxygen in the steel. And the use of ferrosilicon as a deoxidizer in steelmaking, the chemical reaction is relatively small, can effectively protect the safety of the operator, the price, ferrosilicon is relatively low compared to other deoxidizers, thus effectively reducing the cost of steelmaking.

  2. Application of ferrosilicon in casting

    Ferrosilicon can also be used in the casting process. Putting a proportion of ferrosilicon in the iron can promote the speed and quantity of eutectic in the iron, which can greatly improve the density and quality of the castings. It can also promote the fluidity of the iron, making the chemical reaction in the iron more adequate, reducing the poor fluidity of the iron that leads to problems such as clogging of the water outlet. In the production process of graphite castings, ferrosilicon can effectively promote the generation of graphite nuclei, improve the graphite distribution morphology, enhance the quality of graphite castings and avoid the tendency of white mouth.
