The presented paper focuses on numerical modelling of temperature fields of a continuously cast billet. The ProCAST software system, which is based on the finite element method, was used as a simulation tool. The finite element method (FEM) is a modern, highly efficient numerical method for solving technical problems of continuous steel casting. It is currently considered to be one of the most effective approximate methods for solving problems described by differential equations. The effect of the change of the casting velocity on the surface and axial temperature was evaluated on the temperature model of a continuously cast billet of rectangular cross-section with dimensions of 150 x 150 mm, and further, the effect of the change of the casting velocity on the metallurgical length was also evaluated. The simulation tasks were characterized by the invariable content of carbon and the invariable casting temperature. In total, twelve simulation tasks were carried out, marked A1 to C4. Specifically the solidification and cooling problems of the billet were solved for steels with a carbon content of 0.07 wt.%, 0.18 wt.% and 0.83 wt.% at a casting velocity from 2.1 to 2.7 m.min-1 and casting temperatures from 1500 to 1560 °C. Graphical waveforms of surface and axial temperatures of the billet and metallurgical length were obtained from the simulation results. The results of the simulation tasks will be used to verify and substantiate the model.
