Key Features
- Controlled addition: Briquettes break down predictably in molten steel, ensuring uniform silicon distribution
- Low dust formation: Safer for operators and reduces material loss during handling
- Efficient deoxidizer: Silicon reacts with oxygen to form SiO₂, removing dissolved gases and improving steel cleanliness
Benefits in Steelmaking
- Enhances tensile strength and hardness by introducing silicon into the melt
- Improves weldability and impact resistance of structural and HSLA steels
- Supports consistent mechanical properties in rebar, pipeline, and automotive steels
Typical Applications
- Ladle furnace deoxidation in integrated steel mills
- Secondary refining for high-strength construction steels
- Alloying step in electric arc furnace (EAF) steel production
