Abstract: A plant for electroslag remelting of metals and alloys, comprising a cooled mould mounted on a cooled base plate where a slag bath is arranged. Introduced into said slag bath is one end of a consumable electrode, its other end being connected to one of the poles of a current supply source. The plant has at least one non-consumable electrode that is connected to the other pole of the current supply source in series with the consumable electrode. A method of electroslag remelting of metals and alloys in which an electric current is passed through the consumable electrode the slag bath and the non-consumable electrode during the remelting process.
