- • 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.
- • Iron casting deoxidation before pouring.
- • Adjusting Si content in malleable and modular iron alloys.
- • Preparing base iron for subsequent alloying steps.
