Learn why Ferro Silicon 75% is the premier deoxidizer in steel plants and foundries, and how Kenit Metallurgy ensures low aluminum and low carbon grades.

Why Ferro Silicon 75% is Critical

In electric arc furnace and induction melting, uncontrolled dissolved oxygen causes severe blowholes and embrittlement. Gaurav Vij and the metallurgy engineering team at Kenit Metallurgy produce premium-grade Ferro Silicon 70/75% with ultra-low carbon (C < 0.1%) and low aluminum (Al < 1.0%).

Key Metallurgical Functions

  • Fast Deoxidation: Reacts instantaneously with oxygen to form easily separable silicate slags.
  • Silicon Alloying: Imparts electrical resistance, magnetic permeability, and tensile strength in alloy steels.
  • Custom Sizing: Available in 10-50mm lumps for furnace addition and 0-3mm fines for stream inoculation.
