Abstract
There is considered the impact of the vibration mode on the steel 30CrMnSiNiMoA structure after the process of primary crystallization. It has been found that vibration has a positive effect on the process of grain refinement, reduction of the contamination index and the tendency to dendritic liquation. The optimum parameters of vibration have been established for obtaining fine grains and low index of contamination in steel. One of the ways to improve the quality of ingots made of complex-alloyed steels is to control the structure at the stage of primary crystallization using various grain methods, contamination index, dendritic liquation.
