To produce hollow ingots, at least two consumable electrodes having a diameter of at least 1.0 times the wall thickness of the hollow ingots are melted in a short, water-cooled mold that is flared particularly in a T-shape in the area of the consumable electrodes, wherein the inner wall of the hollow ingot is formed by a mandrel with a conicity of at least 1.5% that is installed in the mold from above, and the level of the liquid heel is maintained below the T-shaped flaring of the mold.
