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. | | |

- • 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.
