Definitions

  • the invention relates to a method for reducing the Scrap length when rolling welded seams Metal strips, especially when cold rolling austenitic and ferritic stainless steel strips.
  • tandem lines with two or more rolling stands known. With such tandem streets, either one in essentially straight, tight strip guidance between the rolling stands realized or a loop lifter provided, around a strip length compensation between the rolling stands to be able to generate.
  • tandem mills or rolling mills are becoming increasingly in-line in belt process lines used, e.g. B. in continuous rolling lines, continuous, pickling and Cold rolling lines or continuous, annealing, pickling and cold rolling lines for stainless steel strips, etc.
  • strip processing lines are run continuously through the metal strips to be treated. These metal strips are unwound from coils and connected by means of welds. The roll stands must be carried out regularly when going through the welds be opened.
  • the minimum scrap length corresponds twice the distance between the two rolling stands, because the one corresponding to this distance with respect to the weld length leading strip length also only in one Roll stand and consequently partially rolled is like that in with regard to the band length trailing the weld seam.
  • the rolls are changed every 1 - 10 coils.
  • the invention has for its object a method of Specify embodiment described above, after which there is scrap loss when welding seams pass through by significantly reducing the rolling stands that are open for this and accurate strip tension measurements between the roll stands as well as an exact presetting of the roll stands achieve in a simple and functional manner to let.
  • the invention teaches a method for achieving this object to reduce the scrap length when rolling medium Welded seams of connected metal strips, especially when Cold rolling of austenitic and ferritic stainless steel strips, in a continuous tandem street with at least two roll stands, after which the respective weld seam before the first roll stand stopped or crept is, while the second mill stand that in relation to the The metal strip leading the weld seam rolls on and that Metal strip to be rolled further from a between two roll stands arranged strip store receives the first roll stand opened and the weld seam through the first roll stand is driven through, then the first roll stand closed and the weld after passing through of the strip store stopped in front of the second roll stand or is creeping while the first rolling stand that trailing in relation to the weld seam Metal strip rolls and the rolled metal strip from the strip storage is recorded, the second roll stand is opened and the weld seam is passed through the second roll stand then the second mill stand is closed and so on, and the respective weld in the area of the tape outlet from the connecting them Metal strips
  • the Invention reduces the scrap length in the tandem mill and their rolling stands running and possibly continuous metal belts on practical the seam width of the connecting the metal strips Welds so that the scrap waste goes to zero, in any case extremely minimized.
  • the tandem rolling of the welded metal strips and stainless steel strips In-line in continuously working belt process lines respectively.
  • the invention further teaches that the belt tension in the lead-in area and the run-out area of the roll stands is measured, preferably also in the inlet area and outlet area of the Tape storage is measured.
  • the invention goes the invention from the knowledge that the metal strips between the rolling stands and through the arranged there Tape storage can be deflected by an angle of ⁇ 90 °. Thereby the influence of the bending stiffness of the metal strips the measurement that is too large at small wrap angles Measurement errors leads, negligibly small. It just has to the strip weight must also be taken into account in the measurement. This allows a sufficiently precise tape tension measurement realize between the rolling stands and a more stable Set the rolling process.
  • the belt pulls are expedient behind the first roll stand and in front of the second roll stand set.
  • the tape strength can be determined by measuring the pulling force required for a given degree of stretch in an upstream stretch bending straightening system and / or about measuring the for a given skin pass level required rolling force in an upstream Skin pass mill to be determined.
  • stretch bending straightening depends on the required pulling force for a given one Degree of stretching from the yield point and the flow curve, while the skin pass the required rolling force for a predetermined degree of skin passage from the yield point and depends on the flow curve. It is therefore possible from measurements the tape strength properties on upstream equipment of a coil before rolling to predetermine and via a rule model in the Let the setpoint flow into account. Through improved Target values can be avoided overrolling and strip breaks.
  • the measures according to the invention lead to a higher output during rolling and a higher Productivity of the entire system.
  • the invention also relates to a tandem mill especially to carry out the method according to the invention is suitable and at least two roll stands for rolling Metal strips, especially for cold rolling austenitic and has ferritic metal strips.
  • This tandem road is characterized in that between the two rolling stands a strip store for rolling metal strips arranged with alternately open roll stands is. It can be in front of and behind and, if necessary, between Roll stand strip tension measuring devices can be arranged. Such tape tension measuring devices can also be in front of and behind the tape storage. With these tape tension measuring devices it is preferably load cells under the bearings of pulleys and / or tensioners for the continuous metal bands and a band wrap of at least 45 °, preferably ⁇ 90 °. Actually let it load cells for measuring tape tension on rolls with a Use belt wrapping up to 180 ° or more. Thereby are measurement errors as they are with rolls with small Wrap angles can occur almost completely, can are neglected in any case.
  • the tandem road has two Roll stands 4, 5. Between the two roll stands 4, 5 is a strip storage 6 for rolling the continuous Metal strips 7 with alternately open roll stands 4, 5 shown.
  • Belt tension measuring devices 8, 9 arranged, namely on the one hand in the area of the inlet clamping set 2, on the other hand in Area of the outlet clamping set 3. Beyond that too 6 tape tension measuring devices in front and behind the tape storage device 10, 11 arranged.
  • the belt store 6 has a deflecting roller that can be raised and lowered 12 for the incoming and outgoing metal strip 7, the can be driven.
  • 2 is the two metal strips 7a, 7b connecting Welded seam 13 and in front of the first roll stand 4 stopped there while the second mill stand 5 continues rolling and the metal strip 7b to be rolled the intermediate Tape storage 6 in the sense of a tape storage emptying extracts.
  • 3 is the first roll stand 4th opened, a roll change may have taken place, the weld seam 13 has passed the first roll stand 4 and the first roll stand 4 has been closed again, while the second roll stand 5 has continuously rolled on. 4, the weld 13 is in front of the second roll stand 5 driven and stopped there while the first closed roll stand 4 that of the weld 13 subsequent metal strip 7a rolls and the strip storage 6 is loaded with rolled metal strip 7a.
  • the second roll stand 5 has been opened, the weld seam 13 has been passed through, may have a Roll change took place and the roll stand 5 is again closed while the first mill stand 4 has continuously rolled on and the strip storage 6 has been filled again with rolled metal strip 7a.
  • the cutting out or cutting out of the weld seam 13 can be done in the area of the tape outlet such that the scrap length to the width of the weld 13 is reduced.
