A remelting furnace has a crucible (2) and a raisable pot (3) placed thereon. An electrode rod (6) leads into the pot (3) through a stuffing box (8) borne by a lower platform (9). The lower platform (9) is carried by rods (12, 13) which are fastened each at its upper end to a weighing platform (14). The connection of the lower platform (9) to the particular rod (12, 13) is performed in each case through a releasable clutch (10,11 ). Consequently, a lifter (17) can lift the pot (3) such that it shifts upwardly with the bottom platform (9) relative to the rods (12, 13).
