FIELD: technological processes.
SUBSTANCE: metallic workpiece is led vertically through reservoir with melt and through upstream guiding channel with at least two inductors installed on both sides from it for creation of electromagnet field that holds melt. According to invention it is provided that distance between walls, which limit guiding channel, in direction of normal to the surface of metallic workpiece in the area of guiding channel length by height is made as variable between its bottom side and reservoir bottom, at that walls that limit guiding channel have narrowing or expansion.
EFFECT: melt quieting.
