Abstract:

The article presents the results of computer simulations of steel flow in a six-strand tundish with subflux controller of turbulence and system of argon injection. The authors employed the CFD (Computational Fluid Dynamics) numerical modeling technique to demonstrate the effect of different variants of gaseous bubble shape (spherical and nonspherical bubbles) on the steel flow in the zone of argon injection and shape of RTD (Residence Time Distribution) curves. The computer simulations were performed for isothermal conditions. As a result of computations, fields of steel flow, fields of turbulence intensity, RTD curves and the percentage shares of particular flow zones (stagnant flow, plug flow, and ideal mixing flow) were obtained.
