Abstract
A remelting furnace is disclosed. An electrode rod drive with an electrode rod, as well as a retaining ring to retain a high-current cable, are arranged on a platform which is located on a weighing cell. Even though the position of the high-current cable changes during lowering of the electrode rod supporting a consumable electrode, the recorded weight portion of the high-current cable remains the same, which means that ultimately the change in the weight of the consumable electrode can be determined with the weighing cell.
Claims7
A remelting furnace, comprising:
- a system frame;
- a weighing cell, wherein the weighing cell is mounted on the system frame and wherein the weighing cell supports a platform;
- a mold arranged in the system frame;
- an electrode rod extending substantially vertically and arranged above the mold, wherein a consumable electrode that is meltable is fastenable at a first end of the electrode rod facing the mold;
- an electrode rod holder, wherein the electrode rod is suspended from the electrode rod holder;
- an electrode rod drive, wherein the electrode rod holder is vertically shiftable by the electrode rod drive such that the consumable electrode is positionable into the mold according to a consumption of the consumable electrode;
- and
- a high-current cable, wherein the high-current cable is electrically connected to the electrode rod on a first end and to a bulbar on a second end, wherein the high-current cable is tightly connected to a holder, and wherein the high-current cable extends between the holder and the electrode rod in an arc;
- wherein the electrode rod drive and the holder are disposed on the platform.
