    摘要： 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 comprising a mold wall and an electrically conductive member disposed through the mold wall, contacting the slag with a consumable electrode, 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 through the electrically conductive member.

    摘要： Various non-limiting embodiments disclosed herein relate to nozzle assemblies for conveying molten material, the nozzle assemblies comprising a body, which may be formed from a material having a melting temperature greater than the melting temperature of the molten material to be conveyed, and having a molten material passageway extending therethrough. The molten material passageway comprises an interior surface and a protective layer is adjacent at least a portion of the interior surface of the passageway. The protective layer may comprise a material that is essentially non-reactive with the molten material to be conveyed. Further, the nozzle assemblies according to various non-limiting embodiments disclosed herein may be heated, and may be self-inspecting. Methods and apparatus for conveying molten materials and/or atomizing molten materials using the nozzle assemblies disclosed herein are also provided.
