Key Features
- High silicon concentration: Efficiently removes oxygen from molten metal as SiO₂ slag
- Dense structure: Resists crumbling during handling and transport, ensuring consistent dosing
- Dark grey appearance: Indicates high iron content and proper reduction during production
Benefits in Ferrous Metallurgy
- Improves steel cleanliness by lowering oxygen and nitrogen levels
- Enhances mechanical properties such as strength and magnetic permeability
- Supports production of electrical steels and high-strength construction steels
Typical Applications
- Electric arc furnace (EAF) and basic oxygen furnace (BOF) steelmaking
- Secondary refining in ladles for alloy adjustment
- Production of foundry grades requiring silicon control
