Calcium metal is commonly employed in the high quality and special types of steelmaking.
The calcium treatment can control shape, distribution and fluidity of the modified inclusions.
The following are beneficial effects of using calcium metal in secondary refining.
- Solve the problem of caster nozzle clogging
- Improve the transverse properties including ductility and strength
- Deoxidizer and desulfurizer due to the strong affinity for oxygen and sulfur
In lead-acid battery industry, calcium is a key additive in lead-based alloys to produce the grid and plate for maintenance free battery. It is an ideal material to reduce the corrosion, water usage and self-discharge so that the battery could stand for up to one year and then still have enough power to start the vehicle.
