Abstract:

The inertization practice for a 17.7 tons of steel continuous casting tundish has been studied by means of a threedimensional 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.
