  • Method and device for remelting metal in an electric furnace
    Patent number: 8662142
    Abstract: A method and a device for remelting metal in an electric furnace includes forming a slag bath to form molten material electrodes. The molten metal of the material electrodes solidifies in block form in a crucible apparatus as a result of cooling in such a way that a block growth forms from a block base using a progressing solidification process, wherein the block base is heated by applying energy directly to the block base to influence the cooling process.
