The problem of segregation in large ingots, which are used in energy, heavy engineering, etc., is considered. A new approach to suppressing segregation processes is proposed. It consists in regulating the local crystallization time by organizing a surfaced local metal bath on the surface and adjusting the speed of its movement, while an ingot is formed layer by layer.
