Definitions

  • the invention relates to a method for treating metal strips, in particular hot-rolled metal strips in the inlet part of a continuous pickling line, according to which the metal strip unwound from a decoiler is directed under a predetermined strip tension, then the undirected strip ends are separated to produce directed strip ends and then the strip end of a leading strip Metal strip is connected to the strip end of a subsequent metal strip.
  • Wavy metal strips are actually compressed in the welding clamps and are not welded with the full cross section. Therefore, the band connection can tear in whole or in part in the subsequent stretch bending device. Another problem can be seen in the fact that wavy metal belts cause considerable noise when passing through the treatment or pickling line, namely when rotating the rollers such as deflection rollers, straightening rollers, drive rollers, tension rollers, etc.
  • the invention has for its object to provide a method and a system for treating metal strips, in particular hot-rolled metal strips in the inlet part of a continuous pickling line, the embodiment described above, according to which the metal strips can be easily straightened and connected to each other.
  • the invention in a generic method in that the metal strip is straightened for straightening immediately after unwinding and a band tension which is sufficiently high for straightening bending is produced without increasing the unwinding.
  • the invention is based on the knowledge that, on the one hand, strip corrugations such as edge waves, bowls or the like as well as band sabers or horizontal curvatures can be largely reduced or eliminated by stretch bending straightening, on the other hand stretch straightening immediately after unwinding the metal strips and consequently before Centering and welding of the band ends to be connected can be done.
  • the respective metal strip is trained without deflection in the course of the strip tension generation immediately before the stretch bending straightening.
  • This has the advantage that the formation of flow figures such as roll creases, straightening roll breaks or the like can be avoided with relatively low skin pass degrees - depending on the strip thickness and the material properties - from approx. 0.5% to 1.5%.
  • the subsequent stretch bending straightening with a degree of stretch of 0.5% to 1.5% there are no longer any flow figures. Due to the stretch bending straightening, the entire cross-section of the respective metal strip becomes insensitive to flow figures due to the mutual partially plastic bends. This is of great importance given the constantly growing proportion of hot-rolled and pickled metal strips, especially since flow figures can reappear in subsequent deformations with merely trained metal strips. Because the effect of skin pass rolling only prevents flow figures in the area near the surface.
  • the invention also relates to a plant for carrying out the method according to the invention, in particular the inlet part of a pickling line for continuously running metal strips, with egg Nem decoiler, at least two drivers, a straightening device, scissors and a tape connecting device, for. B. welding device.
  • This device is characterized in that a brake driver, a train driver and a stretch bending device are arranged between the brake driver and the train driver in the tape running direction directly behind the uncoiler.
  • the train driver and the brake driver generate the high band tension required for the stretch bending straightening of the respective metal strip, e.g. B.
  • the invention further teaches that the brake driver as a skin pass mill, e.g. B. duo or quarto scaffold is formed.
  • the invention further recommends that the decoiler and the skin pass mill be arranged in the intended fitting line of the respective metal strip, that is to say a tangential strip run from the decoiler into the brake driver or the skin pass mill is achieved without deflection in order to avoid the formation of flow figures .
  • scale dust extraction can also be provided in the area of the stretch bending device.
  • the invention is explained in more detail below with reference to a drawing which represents only one exemplary embodiment.
  • the single figure shows the inlet part of a pickling line for continuously running metal strips, specifically with an uncoiler 1, a brake driver 2, a train driver 3 and with a stretch bending device 4 arranged between the brake driver 2 and the train driver 3.
  • the brake driver 2 is as Skin pass mill trained.
  • a pair of scissors 5 for scooping the strip end and strip start of the metal strips 6 which are passing through is arranged behind the tension driver 3.
  • This pair of scissors 5 is followed by a welding device 7 for connecting or welding respectively the strip end of the leading metal strip and the strip start of the subsequent metal strip.
  • the welding device 7 is only indicated.
  • the system clearly shows that the respective metal strip 6 is straightened in the stretch bending device 4 immediately after unwinding from the decoiler 1.
  • the strip tension which is sufficiently high for stretch bending straightening, is generated by the tension driver 3 and the brake driver 2 designed as a skin pass mill without increasing the unwinding tension. Consequently, the metal strip 6 is trained without deflection in the course of the strip tension generation immediately before the stretch bending straightening.
  • the decoiler 1 and the skin pass mill 2 are arranged in the intended fitting line of the respective metal strip, which consequently is fed to the skin pass mill 2 without deflection.
