Ferro Silicon Alloy Uniform Chunk Size 72 Content Black Grey For
Steel Plant Refining Use
Ferro Silicon Alloy 72% is a medium‑silicon ferroalloy with uniform chunk size (typically 10–50 mm), ~72% silicon, and a black‑grey metallic appearance. Designed specifically for steel plant refining, its regular geometry ensures predictable dissolution rates and
precise alloy addition. | |

| Deoxidizer, alloying in steel refining |
- •Uniform chunk size: Minimizes segregation in charging systems, enabling even melt
distribution.
- •Reliable deoxidation: Silicon reacts with residual oxygen to form SiO₂ slag, improving
steel cleanliness.
- •Refining efficiency: Predictable reaction kinetics shorten ladle treatment time.
Benefits in Steel Refining- •Enhances final steel mechanical properties (strength, toughness).
- •Reduces non‑metallic inclusions from uneven alloy addition.
- •Supports production of high‑grade structural, pipeline, and
electrical steels.
- •Ladle furnace and RH degasser treatments.
- •Final composition adjustment before continuous casting.
- •Alloying in specialty steel programs requiring tight Si control.
