Original Kurzfassung:
Transient numerical flow simulations of the liquid steel inside of the strand with the scale resolving SAS turbulence model in combination with non-metallic particle transport are presented. One hour of the casting process was simulated for the two cases without and with argon gas injection at the stopper rod tip. The injected gas is assumed to form bubbles, that are transported with the liquid steel flow into the mold and influence the mold flow by their buoyancy forces. The results show irregular fluctuations of the inclusion distribution with alternating asymmetric profiles over the strand width, with time scales in the order of magnitude of several minutes, corresponding to strand length distances of several meters. The case with argon injections shows lower peak concentrations than the case without gas injection.
