Key Features
- Effective deoxidizer: Silicon reacts with oxygen in molten metal to form SiO₂, reducing gas defects and improving casting soundness.
- Foundry suitability: Lump form ensures easy handling in cupola, induction, or arc furnace operations.
- Price stability: Sourced from steady production bases, minimizing cost fluctuations for foundries.
Benefits in Foundry Applications
- Enhances fluidity of molten metal, aiding intricate casting designs.
- Promotes uniform microstructure, reducing cracking and shrinkage defects.
- Supports production of gray and ductile iron with controlled silicon levels.
Typical Uses
- Iron casting deoxidation before pouring.
- Adjusting Si content in malleable and modular iron alloys.
- Preparing base iron for subsequent alloying steps.
