Definitions
- the invention relates to a device for receiving and unwinding at least one wire roll, a so equipped ⁇ te metallurgical plant and a method for unwinding of wire.
- the required wire rolls are usually placed in or on a receiving device next to the oven and threaded the beginning of the wire in a wire conveyor, with which the wire is unwound from the wire reel and transported into the oven ⁇ space.
- Wire conveyors can be operated manually or be automatically controlled.
- the apparatus for receiving a wire roll is the base next to an oven, a working platform on the oven or in general any platform in the vicinity of the oven vessel.
- multiple wire coils are often required, which differ in their chemical composition, to produce a molten metal of desired composition in the furnace vessel. These have been placed next to each other and therefore require a lot of space.
- the residual of the wire reel is exchanged for a suitable for the further treatment of the wire reel. This takes place during and / or after the treatment of a molten metal in the furnace vessel.
- the Benö ⁇ preferential time for changing a roll of wire and re-threading of the wire beginning in the Draht toeinrich- processing is relatively high. The remains of the wire rolls are discarded and remain unused.

Due to an arrangement of several wire rolls of the same or different chemical composition on top of each other, the space required for the required wire rolls is reduced to essentially the space requirement of only a single wire roll. It is equally possible to connect the wire starts and ends of wire rolls to the subsequent unwinding of the wire rolls, as well as simultaneously unwinding wire from two or more wire rolls in the casing. In both cases, a complete use of the used wire rolls is possible, without the need for a time-consuming interruption of the wire feed into a metallurgical plant.
