The SAAC system provides shielding gas to the ladle shroud gasket.
The shielding effect is used to protect the steel from air contact. Oxygen
from ambient air may cause unwanted oxidic inclusions. Ambient air may
cause also nitrogen enrichment, which may have a negative influence on
some steel properties.
To protect the steel stream inside the ladle shroud the FC Technik AG SAAC
system provides different functions. The adequate function can be selected
by operator interaction or by predefined system algorithm.
