Abstract:

The article presents the results of computer simulations of steel flow in a one-strand tundish with low dam. The authors employed the CFD (Computational Fluid Dynamics) numerical modeling technique to demonstrate the effect of different variants of boundary and initial conditions on the numerical result of steel flow and behaviour of non-metallic inclusions (NMI). The computer simulations were performed for non-isothermal, steady and non-steady conditions. To predict of behaviour non-metallic inclusions in the liquid steel “mixture” model and “population balance” model were used. As a result of computations, NMI size distribution curve, RTD curves and the percentage shares of particular flow zones (stagnant flow, plug flow, and ideal mixing flow) were obtained.
