Abstract

Electromagnetic stirring of the melt is an effective and powerful method to influence on directional solidification of different metals and alloys. Three-dimensional numerical modelling is needed to predict or optimize the magnetic field used for the melt flow control. In the paper one created electromagnetic model for three-phases rotational stirrer is described. The model was used to investigate the uniformity of the rotational magnetic field in the melt and its sensitivity to the system geometry. The results of investigation are demonstrated by examples. The model was successfully used to design and modify one laboratory three-phases stirring installation.
