摘要： The invention relates to a method for producing metal blocks or bars, especially from steels and Ni- and Co-based alloys, by melting off consumable electrodes in an electroconductive slag bath using alternating or direct current in a short, downwardly opening, water-cooled mould through which a current contact can be established with the slag bath. The melting current is introduced into the slag bath through the consumable electrode and through the mould in a controlled manner in terms of regulating the distribution of the current between the electrode and the mould; and is conducted back through the mould and the block and the base plate as desired; the division of the currents being adjustable in a controlled manner.

摘要： The invention relates to a method for producing metallic ingots or strands, especially from steel and Ni and Co based alloys, by melting self-consuming electrodes in an electroconductive slag bath, using an alternating current or a direct current in a short water-cooled mould which opens downwards, via which an electric contact can be produced for the slag bath. The supplied melt current is passed via the consumable electrode, the bottom plate, the remelt ingot and the melting bath, and optionally at least one electroconductive element of the mould, to the slag bath. The current distribution can be regulated in a controlled manner and the return circuit of the melt current passes back via at least one other electroconductive element of the mould, which is electrically isolated in relation to a first part of the mould which forms the remelt ingot. The proportion of the entire melt current supplied via the bottom plate is selected between 0 and 100 %. The device for carrying out said method uses a short, water-cooled mould having a bottom plate for creating a remelt ingot, and having at least one electroconductive element which is provided in the region of the slag bath. Said element is isolated in relation to the lower region of the mould, which forms the remelt ingot, and/or in relation to other electroconductive elements.
