  • Patent number: 5274662
    Abstract: A remelting furnace has a crucible and a raisable pot placed thereon. An electrode rod leads into the pot through a passage sealed by means of a seal carried by a lower platform. The lower platform is connected to the pot by a hitch having free play, and can be raised together with the electrode rod by a lift means supported on a weighing platform. In this manner weighing of the electrode rod uninfluenced by the friction forces of the seal is possible. Also, it is possible to lift the pot without increasing the structural height of the structure accommodating the remelting furnace.
