CaSi Cored Wire
Calcium Silicide (compound symbol: CaSi) is a dark grey to black solid compound which is insoluble in water.
| Melting Point | 1010°C (1670°F) |
| Density | at 20°C (68°F): 2.40 g/cm³ |
CaSi is one of the most common calcium product widely used in steel making industry. With its nature of presence as a compound, it is much more stable against moisture and environment as compared to FeCa and Pure Calcium.
The main purposes of utilizing calcium are as followed:
- Deoxidation
- Desulphurization
- Non-metallic Inclusion Morphology Modification
Calcium in cored wire form is gaining its popularity because calcium is:
- Low in density
- Low solubility in molten steel
- Having low melting & boiling point
- High vaporizing pressure
Introducing calcium into molten steel through cored wire will significantly improve the performance in terms of recovery, consistency and reliability.
