FIELD: electricity.
SUBSTANCE: tigel is composed of hollow metal, preferably copper, which are internally cooled tubes (1) mounted with a gap with respect to each other, forming the walls of the crucible. Each tube (1) is formed with a tube bent away from the longitudinal axis in one direction, advantageously by an angle α= 45-60° upper and lower ends, with the formation of all the tubes of this shape of the spatial shape of the tigel in the form of a cylinder (3) with the upper (4) and lower (5) sockets at its ends.
EFFECT: increasing the efficiency of heating the melted material and reducing energy costs by removing the upper and lower water contour from the melt zone and by eliminating the closed loop for electromagnetic waves in the tigel structure that connects the ends of the tubes that would take part of the inductor power while simplifying structure.
