Metallurgical Grade Ferrosilicon for Steelmaking Applications
How does FeSi 75/72 work as a deoxidizer in steelmaking?
In steel refining, oxygen control is critical to avoid defects such as porosity, inclusions, and brittleness. Ferrosilicon (FeSi 75 / FeSi 72) acts as a strong deoxidizing agent by reacting with dissolved oxygen in molten steel.
Key reactions:
  • Silicon + Oxygen → SiO₂ (slag phase removal)
  • Oxygen is transferred from steel into slag
  • Clean molten steel structure is achieved
This makes ferrosilicon deoxidizer FeSi essential in modern steelmaking, especially for high-strength and low-defect steel grades.
Why is ferrosilicon commonly used for oxygen removal in molten steel?
FeSi is widely used because it offers:
  • Fast deoxidation kinetics
  • Stable reaction behavior in high-temperature steel
  • Low impurity introduction compared to alternative deoxidizers
  • Cost-efficient industrial scalability
It is especially important in metallurgical grade FeSi production for continuous casting and ladle refining systems.

FAQ - Ferrosilicon in Steelmaking
How does FeSi 75/72 work as a deoxidizer in steelmaking?
It reacts with oxygen in molten steel to form stable silica compounds that are removed into slag.
Why is ferrosilicon commonly used for oxygen removal in molten steel?
Because it is efficient, stable at high temperatures, and does not introduce harmful impurities.
What advantages does FeSi offer compared to other deoxidizers?
It provides better cost-performance, stable reactions, and improved steel cleanliness.
How does silicon content affect deoxidation efficiency?
Higher silicon content increases oxygen affinity, improving deoxidation strength.
Can FeSi improve steel cleanliness and reduce inclusions?
Yes, it reduces oxygen-based inclusions and improves final steel purity.
Why is ferrosilicon important in high-strength steel production?
It helps control oxygen levels and contributes to desired mechanical properties.
How does FeSi influence steel microstructure after deoxidation?
It stabilizes molten steel composition and reduces defect formation during solidification.
What role does FeSi play in molten steel refining processes?
It acts as both a deoxidizer and alloying element during ladle refining.
