Numerical Modelling in Steel Metallurgy

Popis výsledku v původním jazyce

This is an original editorial for a special issue of Metals journal. Four contributions related to the numerical simulation of steel flow in tundish of a continuous casting machine start with Tkadlečková et al. [4], who provide a numerical analysis of RTD curves and inclusion removal in a multi-strand asymmetric tundish with different configurations of impact pads. The complex procedure of numerical modelling in the programme ANSYS Fluent is described. The papers of Sheng et al. [5-7] describe a computational fluid dynamic (CFD) modelling study for analysing the flow pattern and the residence time distribution in a five-strand tundish. The numerical modelling results are compared to water-modelling results to validate the mathematical model. The volume fraction of different flow regions (plug, mixed, and dead) and the intermixing time during the ladle changeover are calculated to study the effects of the flow control device (FCD) on the tundish performance. Additionally, a mathematical model is developed to study the effects of the flow control devices and the gas curtain on the steel&apos;s cleanliness in a single strand tundish. The results show that the flow control devices and the gas curtain reduce the extent of the dead volumes in the tundish and thus enhance the removal efficiency of the inclusions. For a single-strand tundish, a novel digital design methodology that combines computational fluid dynamics (CFD) modelling and the Taguchi-Grey relational analysis method is also presented. The final quality of steel can also be affected by the conditions of casting and solidification. Therefore, much attention is also devoted to numerical modelling of processes during the continuous casting of steel.
