Silicon calcium (Si-Ca) is an alloy composed primarily of silicon (Si) and calcium (Ca), widely used in metallurgical processes, particularly in steelmaking and cast iron industries. Produced by reducing silica (SiO₂) and lime (CaO) with carbon, it typically contains 30-60% silicon and 10-30% calcium, along with small amounts of aluminum, iron, and carbon.
- Deoxidizer: Removes oxygen from molten steel, improving quality and reducing oxide formation.
- Desulfurizer: Effectively removes sulfur, enhancing mechanical properties of steel and cast iron.
- Inoculant: Modifies cast iron microstructure, promoting graphite formation and improving strength.
- Improves Fluidity: Enhances molten metal flow for easier casting and shaping.
- Reduces Inclusions: Minimizes impurities for cleaner, higher-quality metal production.
