Ferrosilicon is a material with high silicon content, which is widely used in steel making, casting, and other fields. Many sheets of steel and castings use ferrosilicon as a raw material in the production process, and from a certain point of view, ferrosilicon is a necessary raw material for the production process, but also a consumable. This also leads to frequent upstream and downstream trade of ferrosilicon.

The raw material of ferrosilicon is mainly quartz stone, while carbon raw material is needed as a reducing agent, and steel scraps and other raw materials are added in the production process. Different ferrosilicon contains different elements of silicon, which vary in production process and price, etc. In general, people usually distinguish ferrosilicon according to its content of silicon elements, such as ferrosilicon 75, ferrosilicon 72, ferrosilicon 65, etc., where the number represents the content of silicon elements.



Many steel mills and foundries will choose ferrosilicon as raw material and will purchase it regularly, why do these manufacturers favor ferrosilicon so much? Mainly or ferrosilicon has many advantages that other raw materials cannot compare.

  • INEXPENSIVE – Save 30% of production costs
  • EFFICIENT – 40% Reduction in deoxygenation time
  • PREMIUM QUALITY – Improve product quality by 25%
  • HIGH PURITY – 100% compliance with production standards
