Method for producing metal blocks or bars by melting off electrodes and device for carrying out this method

A method for producing metal ingots or billets, especially from steels and Ni- and Co- base alloys, by melting off consumable electrode 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 at option; the division of the currents being adjustable in a controlled manner. The proportion of the overall melting current delivered that is delivered via the consumable electrode can be chosen from between 0 and 100%. A device for carrying out the method has a short, water-cooled mould comprising a base plate and at least one current-conducting element provided in the area of the slag bath, this element being insulated in relation to the lower area of the mould which forms the remelting block; or from other current-conducting elements. The supply of the melting current from at least one current source to the consumable electrode and to at least one current conducting element can be specifically adjusted either separately or jointly by means of a suitable arrangement. The return to the at least one current source from at least one current-conducting element of the mould and the base plate which supports the remelting block can be specifically adjusted either separately or jointly.
