Abstract
This invention is in a method of manufacturing a composite steel ingot wherein a consumable electrode is inserted into an empty space positioned concentrically with said steel ingot, and electric power is fed to said consumable electrode to effect electroslag remelting under a slag bath and then to solidify the molten metal, while taking out an electric current through a plurality of collecting electrodes which are electrically connected to said steel ingot placed on a surface plate, the improvement in that a flow path of the electric current passing from said consumable electrode to said collecting electrodes is moved in the circumferential direction of said steel ingot during said electroslag remelting.
