METHOD FOR PRODUCING METAL BLOCKS OR BARS BY MELTING OFF ELECTRODES AND DEVICE FOR CARRYING OUT THIS METHOD

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.
