Production of blocks or bars made from steels based on nickel and cobalt alloys involves introducing melt current into slag bath through consumable electrode and through mold in controlled manner

摘要

Production of blocks or bars made from steels based on nickel and cobalt alloys comprises melting consumable electrodes (28) in an electrically conducting slag bath using an alternating or direct current in a short downwardly opening water-cooled mold (10) through which a current contact can be made with the bath. The melt current is introduced into the slag bath (24) through the electrode and through the mold in a controlled manner in terms of regulating the distribution of the current between the electrode and the mold and is conducted back through the mold and the block and a base plate (14). The division of currents is adjustable in a controlled manner. An Independent claim is also included for a device for producing blocks or bars made from steels based on nickel and cobalt alloys. Preferred Features: The amount of melt current introduced over the electrode is between 0 and 100%. Bars can be produced continuously or in stages.
