Definitions

  • the invention relates to a hot rolling mill having at least one flatness measuring roller which influences at least one upstream and / or downstream roller table and positions of at least one of the stands.
  • the invention is based on the object of designing a flatness measuring roller for hot rolling mills in such a way that it is particularly protected against the environmental influences.
  • the problem is solved with the features of claim 1. They allow you either to advance the flatness measuring roller into the gap created with its uppermost surface line over the support level of the roller table and then lower a hold-down roller while extending at least one roller table roller, or to lower the flatness measuring roller downwards and to close the gap created in the roller table by a roller table roller conclude.
  • the flatness measuring roller and the roller table roller can be arranged in a box which can be rotated about an axis such that the flatness measuring roller and the roller table roller can alternatively be guided into the working position by turning in the same sense.
  • the flatness measuring roller and the at least one roller table roller in a box which can be pivoted about an axis such that the flatness measuring roller and the roller table rollers can alternatively be guided into the working position by pivoting up and down.
  • FIG. 1 schematically shows the arrangement of a flatness measuring roller and roller table roller mounted in a rotatable box
  • FIG. 2 shows a section of a roller table of a hot rolling mill with the flatness measuring roller and roller table roller containing rotatably drivable box and a lowerable hold-down roller
  • FIG. 3 shows a section of a roller table of a hot rolling mill with a swiveling box containing a flatness measuring roll, the flatness measuring roll being brought out of action
  • Figure 4 is an illustration according to FIG. 3, but in which the flatness measuring roller is brought into the operative position
  • FIG. 5 shows the longitudinal section through a box according to FIG. 3 or 4 with
  • FIG. 1 shows two circular disks 1 and 2, which are connected to a box 4 by a screen plate 3.
  • the box 4 is rotatably held on the left side in a bearing 6 by means of a pin 5.
  • On the right side it has a pin 7, which is mounted in a pivot pin 8, which in turn is held in a bearing 9 and carries spur gears 1 1 and 12 surrounding the bearing 10 of the pin 7.
  • Helical gear 11 meshes with gear 13, which is arranged in a rotationally fixed manner on the drive pin of roller table roller 14.
  • the spur gear 12 meshes with the gear 15, which is rotatably provided on one of the shaft journals of the flatness measuring roller 16.
  • the roller table roller 14 and the flatness measuring roller 16 are held in bearings in the circular disks 1 and 2 of the box 4. This results in the following options: to convert from an effective flatness measuring roller 16 to an effective roller table roller 14, the pin 5 is driven by an unillustrated drive in the direction of arrow 17 until the box 4 rotates by 180 about its axis of rotation given by pins 5 and 7 ° turned. This rotation can be controlled by electromechanical or electronic sensors that monitor the rotation.
  • the circular disk 1 may be limited, but it is also possible, for example, to equip the circular disk 1 with two notches 18 formed as shoulders or notches and to bring the disk to a standstill, not shown, scanning its circumference and inserting in front of the latch 18, and in this position to hold or lock if necessary.
  • the pivot pin 8 is driven in the direction of the arrow 19 by drive means, also not shown. He takes the spur gears 11 and 12 with him, which may possibly also be made in one piece or in one piece with him, and thus drives both the roller table roller 14 and the flatness measuring roller 16 via the gears 13 and 15, so that if one of them in Is brought into the active position, it is already rotating at the feed speed of the roll as peripheral speed.
  • the distance between the bearings of the roller table roller 14 from the axis of rotation of the box 4 is selected so that when the roller table roller 14 is pivoted in, the top surface line thereof is aligned with the upper surface lines of the other roller table rollers, while the flatness measuring roller 16, which is usually made with a larger diameter is in active position with its uppermost surface line above the level of the upper surface lines of the roller table.
  • FIG. 2 An integration of the box into a section of a hot rolling mill is shown in FIG. 2.
  • the roller track 20 is shown, from which the roller table roller 14 is pivoted downwards in the direction of arrow 21 and the flatness measuring roller 16 is pivoted in for this purpose.
  • the hold-down roller 24 mounted on the free end of the swivel arm 23 is lowered by means of the hydraulic cylinder 25. Compressed air had already been applied to the swivel arm 23, the air coming out of the slits in the guide plates 26 as air indicated by arrows 27. Flow emerges downwards and presses the hot rolled strip 22 against the flatness measuring roller 16 and the roller table 20, a measure which proves to be necessary with 130 thin hot strips.
  • the pivot angle can be used to determine the thickness of the rolling stock.
  • roller table roller 14 and the flatness measuring roller 16 are retracted in such a way that the hot rolled strip 22 is started tangentially and thus avoiding excessive forces, and since both the retracting the roller table roller 14 and the flatness measuring roller are retracted 16 with the same rotary
  • the flatness measuring roller 16 is expediently passed into its working position after passing the beginning of the strip
  • FIG. 3 shows a section of a hot rolling mill similar to FIG. 2.
  • the rotatable box 4 is made up of a pivotable box 4 ".
  • the box 4 ' can be pivoted about a pivot point 28.
  • the box 4 ' has roller table rollers 14' and a flatness measuring roller 16 '.
  • the flatness measuring roller 16 ' is pivoted out of the support plane of the roller table 20'.
  • the roller table rollers 14 ' close the gap created here.
  • protective devices 30 to 33 are shown, which are designed as belt guide tables. The protective devices 30 to 33 cause, in particular, scale and dirty cooling water from the
  • the swivel arm 23 with the hold-down roller 24 is brought out of action in FIG. 3 via the hydraulic cylinder 25.
  • Figure 4 shows that the box 4 'was pivoted by the piston-cylinder unit 29 in a position-controlled manner. Stops (not shown) and locking means (also not shown) can hold the box 4 'in the operative position in which the flatness measuring roller 16' has been pivoted upward beyond the support plane of the roller table 20 '. The hold-down roller 24 ensures
  • FIG. 185 sufficient wrap around the flatness measuring roller 16 '.
  • the flatness measuring roller 16 ' can be cleaned and cooled via cooling devices 34 and blow-off devices 35.
  • Figure 5 shows the box 4 ', which are pivotable about the pin 36.
  • the roller table rollers 14 'and the flatness measuring roller 16' are driven by separate drives 37, 37 'and corresponding spindles 38, 38'.
