Heated gutter for transportation of molten metals contains a body (1) formed by the bottom and two side walls, a refractory channel (2) for molten metal, an insulating layer (3) between the channel (2) and the walls of the body, heating elements located along the sides of the refractory channel, and a metal protective barrier (4). The heating elements are made in the form of at least one flat flexible electric heating element (5), a metal pressure plate (6) and an insulating layer (3) of the respective side placed between them. A protective barrier (4) is placed between each heating element and the corresponding outer side wall with the possibility of interacting with the outer surface of the side wall of the refractory channel. Each heating element is installed with the possibility of pressing it and pressing the protective barrier against the outer side wall of the refractory channel by means of at least one pressing element (7).

EFFECT: invention provides heating of the metal on the straight sections of the gutter and on its turns, tees, short lines, as well as maintainability of the gutter.
