Abstract
A DC electric arc furnace has an electric connector for a melt in the furnace's hearth in the form of an elongated metal conductor having a refractory enclosure exposing an inner end of the conductor for contact with and incidental melting by the melt, the refractory enclosure being formed by a projection of the hearth's lining extending from the inside of the hearth to beyond the hearth's outside with a metal shell enclosing the hearth's projection on the outside of the hearth.
