Ferrosilicon45 75 used as deoxidizers in steel

Silicon iron powder presents diverse application scenarios due to differences in silicon content. Low silicon products are suitable for the preparation of suspended media and electrode coatings in mineral processing; The high silicon type serves the purification of semiconductor grade silicon in the electronics industry and the synthesis of organic silicon in the chemical industry. 75 silicon iron powder, as the core deoxidation material for steelmaking, significantly improves the performance of steel through a dual deoxidation mechanism of precipitation/diffusion: enhancing mechanical strength and hardness by about 15-20%, increasing elastic limit by more than 30%, optimizing the magnetic permeability of transformer steel (typical value>18000 Gs/Oe), and reducing hysteresis loss (<1.2 W/kg). Different steel grades need to be matched with specific silicon content iron powder. Our company specializes in the full range of specifications such as 75 # (Si74-80%) and 72 # (Si70-75%). Technical parameters can be found in the product manual. Welcome to inquire for more details.
