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), approximately 72% silicon content, and a black-grey metallic appearance. Designed specifically for steel plant refining applications, its regular geometry ensures predictable dissolution rates and precise alloy addition.

Key Features
- 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
Typical Applications
- Ladle furnace and RH degasser treatments
- Final composition adjustment before continuous casting
- Alloying in specialty steel programs requiring tight Si control
