Definitions

  • the present invention relates to a rolling line for producing a metal strip, in particular a hot rolling line for producing steel strips, and a method for producing a rolling train.
  • rolling mills For the production of metal strips, in particular in the production of sheets, rolling mills are used.

  • Lie in the individual rolling stands progressively thinner rolling gaps, so that after the last rolling stand, the desired thickness of the rolled metal strip is reached.
  • US 3,614,881 shows a cold rolling line for rolling a strip, with a plurality of work rolls.
  • an input guide device and a supply guide which are respectively arranged adjacent to the work rolls and can be brought into contact with the side edges of the strip, can be dispensed with a vertical adjustment for the tape guide.
  • EP 0 721 813 A1 shows a device for guiding hot rolled strip by an inductor of an induction heater, which is arranged between two adjacent rolling stands. Between the rolling stands are two guide rollers over which the belt is guided, and a Switzerlandmessaku with a tension measuring roller, which ensures in conjunction with the two guide rollers a tension control for the band arranged.
  • DE 40 31 666 A1 shows a generic rolling mill for producing a metal strip, with the features according to the preamble of claim 1.

  • the looper roll is arranged within the volume enclosed by one of the roll stands.
  • the volume of the roll stand is defined by the respective outer edges of the roll stand, that is, for example, the outer edges of the frame of the roll stand. Accordingly, at least the looper roller within the "shadow" of the rolling stand, so it is covered by the frame of the roll stand parallel to the recorded in the roll stand work rolls when looking sideways of the rolling mill, so that it is not visible.
  • the looper roll is arranged parallel to the orientation of the work rolls of the rolling stand.
  • the aggregate arranged adjacent to the roll stand can be a further roll stand, a reel, a straightening machine, a winding furnace, etc.
  • the compact arrangement can also be achieved that between the individual rolling stands at conventional distance (or at almost conventional distance) more space for other components such as induction heating, hold-down rollers, a belt cooling, a descaling, a leveler, a separator or a Scissors can be accommodated.
  • the looper roller is arranged in a region between the rolling mill center and the rolling mill edge. In this way, a correspondingly compact design can be achieved.
  • the looper roller is preferably attached to a lever which is adjustable by means of an actuator, in particular by means of a hydraulic cylinder, hinged to the rolling stand.

Also in this way, a compact design of the rolling stand with the associated components can be achieved such that the inlet side guides continue to press into the roll stand.

  • a compact design of the induction heating is understood to mean an induction heating which has a relatively small extent in the direction of strip travel.
  • the expansion of the induction heating in the strip running direction is lower than previously known.
  • the extension or length of the induction heating in the strip running direction is preferably less than 1500 mm and is preferably between 600 mm and 1100 mm. In this way, it is achieved that the distances between the roll stand and the adjacent aggregate, in particular a further roll stand, can be reduced, which results in a shortening of the entire rolling train and in an improved temperature control of the strip.
  • the induction heating can be arranged between the rolling stands with a small footprint, but it is also the space required for the Induktorspeisung next to the rolling gears or the rolling motors reduced.
  • the inductor feeds are preferably arranged on one side of the rolling train, particularly preferably on the drive side of the rolling train.

  • the two Induktorspeisonne not only compact side by side, but particularly preferably arranged one above the other.
  • the inductor and the associated Induktorspeisung can be offset in the strip running direction against each other so that the inductor is not centrally located on the Induktorspeisung, but just offset. In this way, further space can be saved here and the simultaneous operation of two induction heaters one above the other can be achieved so that the Induktorspeisache quasi have the same "footprint", but the inductors are shifted in the strip running direction from the middle of Induktorspeisache out.
  • busbars for example, a rear inductor with an inductor arranged on top, and a front inductor with a bottom arranged Induktorspeisung be connected.
  • Inductor and Induktorspeisung can be moved together with each other perpendicular to the direction of tape travel and be adjusted accordingly in their common position of the respective width of the belt without the induction heater would consume a lot of space in the direction of tape travel.
  • the induction heater In order not to accidentally heat up the respective units adjacent to the induction heater, the induction heater must maintain a certain minimum distance from the respective units. Preferably, a minimum distance of 150 mm is maintained here. Preferably, this distance is also in Belt direction between the induction heating and the adjacent rolling stands, between which the induction heating is arranged, complied with. This results in a particularly compact arrangement of the looper roll and / or the side guide in the shadow of the respective adjacent rolling stands in combination with the arranged between these rolling stands compact induction heater.
  • inductor and inductor are connected together so that they can be easily solved for maintenance purposes or in set-up operation of each other.
