The electromagnetic stirring during the continuous casting became indispensable to obtain steel with high quality. Despite the fact that the stirring effects during the solidifying process are not very well known from the theoretical point of view, these effects can be studied on the steel flow. The aim of this work is to study the magnetic and the fluid dynamic effects due to a rotatory stirrer for billets. A model solved by the finite element method was developed using the Ansys commercial package to solve the coupled magnetic-fluid dynamic problem. To make a comparison simulations with two current values were carried out and the main differences concerning the fluid flow and the thermal profile were analyzed.
