Definitions

  • the invention relates to a Steckel mill with at least one Reversing scaffold and on the inlet and outlet sides of the reversing scaffold arranged drivers and winding ovens, which have roller tables for the strip to be rolled are connected to each other, with at least one of those formed between the winding furnaces and the reversing stand Sections at least one heating device is provided, which covers at least one area of the respective section and wherein at least one control device is provided, which in Depending on the strip temperature to influence the heating output can
  • Such Steckel rolling mills are known from JP-A-59 191502. They work as follows: The pre-rolled strip is under the inlet side Winding furnace and through the inlet-side driver Reversing frame introduced for tapping. After the first stitch the rolling stock is threaded into the winding furnace on the outlet side. After this the tape has been wound in the winding furnace on the outlet side a predetermined between the winding furnace and the reversing stand Belt tension built up and the belt at appropriate speed rolled. If the end of the strip runs into the Steckel rolling mill, the system braked so that the end of the tape behind the Rolling nip of the reversing stand, but in front of the outlet side Driver comes to a standstill. During reversing the Roll gap set for the next pass.
  • the outlet side The driver inserts the tape into the reversing frame for tapping.
  • the tape is inserted into the inlet side Threading the winding oven.
  • the beginning of the band comes at the end of the second Stab between the driver on the inlet side and the reversing frame to a standstill.
  • JP-A-59 191502 has temperature sensors and influences them the temperature of the beginning or end of the strip via the heating devices in that an adjustment to the remaining strip temperature he follows.
  • the measuring device is slow and imprecise, so that a optimal adjustment of the strip temperatures is not guaranteed.
  • the invention is based, so Steckel rolling mills to design that there are no large fluctuations in rolling force over the length of the strip the tape is of constant quality rolled and scrap is avoided.
  • the Solution proposed here causes predetermined areas of the belt, especially the one that is not in the heated winding furnace Part of the rolled strip on one, corresponding to the rest of the rolled strip adjusted temperature can be brought.
  • Adjustable heating devices are known from SU-A-728 955, controlled by belt position sensors, one However, band tracking is not suggested here.
  • each only the heating device activated each in the tape running direction before the Reversing frame is arranged, so it is ensured that the belt Before the stitch in the reversing frame is heated accordingly however, the strip running out of the reversing stand does not heat up is subjected.
  • the invention is explained below with reference to a drawing.
  • the figure shows a Steckel rolling mill 1.
  • the Steckel rolling mill 1 consists of a reversing frame 2, two drivers 3, 3 ', two reel furnaces 4, 4' and a roller table 5, which the reversing stand 2 connects to the drivers 3, 3 'and the reel furnaces 4, 4'.
  • the roller tables 5 ', 5' ' serve that band 6 the Steckel rolling mill 1 (5 ') or to be discharged from it (5 ").
  • heaters 7, 7 'and 8, 8' are provided between the drivers 3, 3 'are above and below the roller table 5 heaters 7, 7 'and 8, 8' are provided. These heaters 7, 7 '; 8, 8 'are with outputs of a control device 9 connected. Via the input line 10, the control device 9 the strip temperature setpoint and via the input line 11 the Belt position setpoint are supplied by a computer 12. This Belt setpoints can also be set via the input lines 13, 14 feed from an input unit 15.
  • the actual strip temperature values are the control device 9 from the Belt temperature actual value transmitters 16, 16 'are supplied while the actual position values the belt of the control device 9 via a belt tracking device 17 can be connected to their various input signals from in the Steckel mill 1 to determining, not shown Received encoders received.
  • the control device 9 is thus dependent on the Belt temperature and / or the belt position and / or the belt running direction the heating output between 0 and maximum output as required adjusted.
