There is executed the investigation of convective flows redistribution during the liquid metal pouring into mold on the base of mathematical and computer simulation in this work. It is shown that during the ingot pouring with 114 kg/s mass velocity pouring the liquid metal overheat over liquidus iso therm is removed and the separation of metal layers cooled during the mold filling takes place. This phenomenon can influence on the appearance of chemical and physical heterogeneity in ingots during their formation.
