Definitions

  • the invention relates to a system for the continuous treatment of thin sheet metal with a strip inlet part and a strip outlet part and an oven arranged in between with an inlet strip store in front of the furnace and an exit strip store behind the furnace, and furthermore with a dip coating part between the furnace and the strip outlet part.
  • Such a system has become known from DE-OS 2710041.
  • This system is used for the continuous annealing and hot-dip galvanizing of thin sheet, has a furnace part and a dip galvanizing part connected downstream in the direction of strip travel. Furthermore, an inlet belt store is arranged in front of the furnace part and an outlet belt store is arranged behind the galvanizing part. In front of the inlet belt store, the inlet section is provided with decoilers and a belt cleaning system. In addition to the straightening, an additional strip aftertreatment is carried out in the outlet section before the galvanized strip is fed to take-up reels.
  • This single-purpose system can only work economically if it can be operated continuously for long periods without downtimes. However, this is only possible for the operators of hot-dip galvanizing plants, where there is sufficient capacity to be able to fully utilize such an efficient hot-dip galvanizing plant in terms of capacity.
  • DE-AS 2729931 discloses a tower furnace for the heat treatment of rolled sheets. A variety of different heat treatments are to be implemented with the tower furnace. This tower furnace can either be part of a system that is only suitable for carrying out heat treatments, or it is integrated in a system that carries out hot-dip galvanizing in addition to the heat treatment.
  • GB-PS 1 435 651 only discloses an annealing furnace for producing deep-drawable thin sheets, the cooling part of which, in addition to a conventional slow-acting gas cooling section, has a fast-acting water cooling section.
  • the strip material can be guided through the water cooling section in a number of loops via a larger number of deflection rollers, while on the other hand there is also the possibility of passing the strip material directly through a protective channel bypassing the water cooling section.
  • the invention is therefore based on the object of creating a system of the type mentioned which, as a multipurpose system, can be operated as economically as possible, both for the continuous annealing of thin sheet and for the annealing and dip coating of thin sheet.
  • the beginning of the dip coating part can be coupled to the outlet of the furnace and the end of the dip coating part can be coupled to and decoupled from the beginning of the strip exit part, so that the system alternately either for continuous annealing and for dip coating of sheet metal or exclusively can only be used for the continuous annealing of thin sheet.
  • the requirements for a multi-purpose system are also given in the same technical design parameters as strip dimensions, coil weights, strip speeds, furnace temperatures and the like.
  • the feed material, cold-rolled thin sheet from the tandem mill is also the same for both processes, namely for annealing and for dip coating.
  • the strip end located in the extension channel behind the furnace is moved so far that it can be connected to the strip beginning which also remains on the exit side of the dip-coating part.
  • a common furnace part is provided for the continuous annealing of thin sheet and for the dip coating of thin sheet.
  • the dip coating part can be designed as a hot-dip galvanizing part, as a fire aluminizing part, as a hot-dip tinning part or the like.
  • the furnace part and the dip coating part are followed by a common outlet part with an outlet belt store. This ensures that all material passes through the same distance to the decoiler during the transition from dip coating to continuous annealing or vice versa.
  • An extension channel with tape threading storage is expediently arranged between the furnace part and the dip coating part. This makes it possible to carry out the coupling without the entire inlet part having to be actuated with the furnace part.
  • the tape threading store is advantageously designed as a vertically movable tape storage roll.
  • the tape storage roll is located outside the extension channel in normal operation.
  • Normal operation is to be understood as the normal operation of this system, that is to say the operation which is carried out after the coupling and uncoupling have ended.
  • a hand-operated pair of scissors is expediently provided on the inlet side and a driven pair of cutting shears on the outlet side.
  • the system in such a way that to connect the dip coating part, the beginning and end of the strip are to be connected on the entry side by manual welding and on the exit side by a stitching or welding machine.
  • the welding is carried out by hand on the entry side above the coating vessel and on the exit side directly behind the cutting shear by a stitching or welding machine.
  • the object on which the invention is based is also achieved according to the invention in that the outlet of the furnace can be coupled to the start of the dip coating part and the beginning of the outlet belt store to the end of the dip coating part and can be disconnected therefrom, so that here too the system can be used alternately either for continuous annealing and dip coating of thin sheet or only for continuous annealing of thin sheet.
  • the prerequisites for a multi-purpose system are also given here in the same technical design parameters as strip dimensions, coil weights, strip speeds, furnace temperatures and the like.
  • the feed material, cold-rolled thin sheet from the tandem mill is also the same for both processes, namely for annealing and for dip coating.
  • a common furnace part is expediently provided for the continuous annealing of thin sheet and for the dip coating of thin sheet.
  • a common outlet belt store is arranged downstream of the furnace part and the dip coating part. This ensures that during the transition from dip coating to continuous annealing or vice versa, the strip supply required for coupling can be drawn out of the discharge strip store without the units in the discharge part having to be actuated against the strip running direction.
  • the system can be designed in such a way that a pair of shears is arranged at the outlet of the furnace section and at the entrance to the exit belt store. It is thus possible to split the strip at the end of the furnace part and at the beginning of the exit strip storage without major interruption when transitioning from dip coating to annealing or vice versa.
  • a stapling machine is expediently arranged at the entrance of the dip coating part and at the entrance to the exit belt store. This also ensures that the respectively opposite and associated band ends can be connected to one another.
