Abstract

The present disclosure relates to electroslag remelting methods and apparatus for producing metallic ingots, as well as to articles of manufacture made from materials processed according to the methods and/or using the apparatus. One such method includes disposing slag within a withdrawal mold (2) comprising a model wall and an electrically conductive member (8) disposed through the mold wall, contacting the slag (4) with a consumable electrode (6), and heating the slag by conducting an electrical current through the consumable electrode into the slag, thereby melting at least a portion of the consumable electrode in contact with the slag. At least a fraction of the melted portion of the consumable electrode is collected in the withdrawal mold to form the ingot. At least a portion of the electrical current is conducted form the slag (4) through the electrically conductive member (8).
