The inertization practice for a 17.7 tons of steel continuous casting tundish has been studied by means of a three-dimensional non-isothermal mathematical model. The model considers a single gaseous phase composed of argon and air. Turbulence was accounted for with the standard k-ε model. The calculations were carried out using the commercial CFD software ANSYS CFX. Different configurations of the inertization system were simulated and a novel approach was utilized to discuss model findings. The results indicated that the present configuration is ineffective and new ones were suggested.

W pracy omówiono modelowanie procesu wytwarzania atmosfery obojętnej w przestrzeni roboczej kadzi pośredniej ciągłego odlewania stali. Zastosowano przestrzenny model dla warunków zmiennej temperatury. Model uwzględnia fazę gazową składającą się z argonu i powietrza. Turbulencje w przepływie gazu modelowano za pomocą standardowej metody k-ε. Symulacje CFD przepływu (ang. Computational Fluid Dynamics) wykonano w komercyjnym oprogramowaniu ANSYS CFX. Rozważono różne konfiguracje procesu tworzenia atmosfery obojętnej. Analiza wyników symulacji wykazała, że obecnie stosowana konfiguracja procesu jest nieefektywna. Na podstawie przeprowadzonej analizy uzyskanych wyników zaproponowano nowe podejście do tego procesu
