Abstract

Numerical modelling is becoming an essential part of research in the field of steel metallurgy at present. In numerical modelling, the operating equipment is replaced by a mathematical model, which consists of a system of partial differential equations. Numerical modelling is used to display processes and results that cannot be monitored under operating conditions. From numerical modelling we can obtain the results of the flow field, we can monitor the change in temperature and monitor the wear of the refractory lining, etc. This paper deals with numerical modelling of steel flow in the tundish. The tundish is a very important part of continuous casting. It supplies liquid steel during the ladle change and distributes steel between casting strands. The tundishes are made of a welded steel shell and lined with a refractory material. During casting steel, the tundish is the last reactor where it is possible to influence the quality and purity of the cast steel. It is necessary to know the processes in the tundish. This presented paper compares the results obtained by flowing steel in the tundish at non-isothermal conditions. A five-strand asymmetric tundish for bloom casting was used for numerical simulations. The paper also provides an overview of the issues of numerical simulations and their applicability in practice. Fluent software, which is part of the ANSYS package, was used for numerical simulations.
