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. | | |

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.
- • Primary steelmaking (BOF, EAF) deoxidation.
- • Ladle refining for structural and pipeline steels.
