摘要
An electroslag remelting or refining method and arrangement for removing undesired elements, particularly H.sub.2 and O.sub.2, from metals. A water-cooled mold having a bottom plate is adapted to being raised in known manner. A growing metal ingot solidifying in the mold has a solidified portion and a liquid metal sump portion. A layer of molten slag covers the liquid metal sump. A self-consuming electrode extends into the slag. An a.c. source is connected between the electrode and bottom plate. Oppositely-poled auxiliary electrodes are included which are in electrical contact with the slag cover, the auxiliary electrodes being connected to opposite polarity terminals of a d.c. source.
