- • 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.
- • Electric arc furnace (EAF) and basic oxygen furnace (BOF) steelmaking.
- • Secondary refining in ladles for alloy adjustment.
- • Production of foundry grades requiring silicon control.
