ABSTRACT:
In a plant a carrier for withdrawing an ingot is a drum, rotatably mounted about the horizontal axis thereof, adjacent to the side of a mould near its wall shaping the internal surface of the ingot and coaxial with the wall, with a base plate having a dummy bar and an electrode holder being fastened to the drum shell; the electrode holder being electrically insulated from the drum and carrying at least one electrode curvilinear in shape and encompassing a part of the drum and having a clearance therewith to preclude electrical contact between the drum and the electrode; the drum, while turning, serving also as a mechanism for feeding the electrode into the mould melting space.
