| Main use |
Deoxidizer, silicon alloying in steel |
Key Features
- High silicon concentration: Quickly removes oxygen from molten steel as SiO₂ slag, reducing porosity and improving cleanliness
- High reactivity: Ensures fast dissolution, shortening refining time
- Dense lumps: Resist crumbling during transport and charging, allowing consistent dosing
Benefits in Steel Industry
- Enhances strength, toughness, and magnetic properties of carbon and alloy steels
- Improves weldability and reduces cracking in structural steels
- Supports production of electrical steels and HSLA steels where precise Si control is critical
Applications
- Primary steelmaking (BOF, EAF) deoxidation
- Ladle refining for rebar, pipeline, and automotive steels
- Alloying in specialty steel programs
