Ferro Silicon 75 Lumps High Carbon Low Aluminium Grey Black For Steelmaking Deoxidizer
Ferro Silicon 75 lumps are a medium-carbon, low-aluminium ferroalloy containing approximately 75% silicon by weight, with the remainder mainly iron and controlled levels of carbon and aluminium. Their grey-black metallic appearance reflects the dense, solid form ideal for bulk addition in steelmaking furnaces.

| Main use |
Deoxidizer and alloy additive in steelmaking |
Key Features
- Effective deoxidizer: Silicon reacts with oxygen in molten steel to form SiO₂, reducing oxygen content and preventing porosity.
- Low aluminium: Minimizes unwanted Al₂O₃ inclusions that can affect steel cleanliness.
- Medium-high carbon: Helps adjust carbon levels when intentional for certain steel grades.
- Robust lumps: Easy to handle in charging buckets or conveyor systems.
Typical Steelmaking Benefits
- Improves steel fluidity and reduces gas defects.
- Allows precise control of final steel chemistry.
- Supports production of carbon and alloy steels where aluminium pickup must be limited.
Applications
- Primary steelmaking (BOF, EAF) deoxidation.
- Ladle refining for structural and pipeline steels.
