The effect of endogenous vibration treatment on kinetic parameters and characteristics of structure of a solidifying melt was studied on 16,3 t ingot of steel grade Х18Н10Т. Significant improvement in the quality of the ingot, homogeneity and dispersion of its cast structure, change in the extent of the main structural zones along the height and cross section of the ingot, the distribution and the number of nonmetallic inclusions are shown. An increase in impact strength by 25 – 30 % in rolled steel made from the ingot metal, which was subjected to endogenous vibration treatment during crystallization of the melt, was established.
