The paper presents mathematical modeling of structural elements at magnetic-hydrodynamic mixing system for silicon melt in experimental system of directional solidification GT-DSS450TM. The aim of this work is to assess the influence of magnetic field on structural elements in the system of directional solidification, such as a frame for attaching insulation and walls of working chamber and to model possible negative effects of this influence. A series of calculations were carried out to determine parameters such as induced currents in structural elements, the speed of mixing on the surface of melt, efficient inductance of inductors. A method for minimizing the parasitic effect of magnetic field on chamber walls is proposed. The studies were carried out by the method of mathematical modeling using COMSOL Multiphysics software package.
Key words: mathematical modeling, silicon, magnetohydrodynamic mixing, ferromagnetic screen.
