Abstract
The structure formation of ingots crystallizing from the melt takes place near the crystallization front in boundary layers (namely, in the hydrodynamic boundary layer whose thickness is determined by the melt stirring intensity and temperature and by concentration layers in the case of alloy crystallization), and depends on heat and diffusion fluxes that specify the melt solidification rate. Therefore, we focus here on studying the influence of electromagnetic stirring on heat and momentum transfer near the crystallization front. Figs 9, Refs 4.
