This work shows the use of some basic animation techniques to develop a computer simulator capable to display the heat transfer of steel during a continuous casting process. This is the most popular method to produce steel in big bulks. Nevertheless, continuous casting involves the interaction of complex heat transfer phenomena such as conduction, radiation and forced convection, and appropriate algorithms with graphical tools must be developed to display thermal and solidification profiles according to temperature values. Here a 2D model was applied for calculation purposes; nevertheless the animation techniques employed allowed us to display a 3D representation. Furthermore, additional enhancements were created to show the internal thermal behaviour. A math model provided a good approach for process simulation and the animation procedures were successfully tested to provide a good visual display.
