Apparatus for electroslag remelting of consumable electrodes

摘要

In an electroslag remelting apparatus comprising electrode holders adapted to hold at least two consumable electrodes connected to different terminals of an a.c. power source, the mould and the bottom plate are electrically connected to each other and, through rectifiers, to the a.c. power source, the rectifiers being connected to the same terminals of the a.c. power source as the electrode holders. The rectifiers are so connected into the circuit as to provide a flow of only direct current through the bottom plate and mould towards the a.c. source through said rectifiers.
