Definitions

  • the invention relates to a device for detecting the roll gap between two work rolls of a roll stand with a roll stand and a work roll bending device, in which each of a total of four work roll chocks, which support the work rolls at their ends, over two, on opposite sides of the respective Hydraulic cylinders arranged on the work roll are directly adjustable relative to the roll stand.
  • the rolling stock thickness As a controlled variable of interest, cannot be measured in terms of control technology at the point of its origin, namely the roll gap, and therefore cannot be used for the direct correction of faults, such as eccentricities of the rolls, can be used.
  • the invention has for its object to enable a largely direct detection of the roll gap between the work rolls of a roll stand, with a roll stand with a work roll bending device, as is assumed, for example, from "Handbook of Manufacturing Technology", volume 2/1, Carl Hanser Verlag, 1983, page 453, picture 80.
  • the object is achieved in that position transmitters are installed in the hydraulic cylinders in the device of the type specified at the outset and in that the position transmitters are followed by an evaluation device for determining the roll gap from the position values supplied by the position transmitters.
  • the roll stand shown in FIG. 1 consists of a roll stand 2 in which an upper and lower support roll 3 or 4 and two work rolls 5 and 6 are arranged.
  • the two support rollers 3 and 4 are supported at their two ends via Morgoil bearings in support roller chocks 7 and 8; the two work rolls 5 and 6 are mounted in corresponding work roll chocks 9 and 10.
  • 1 shows the roll stand 1 from its drive side, that is from the side on which the rollers are driven, so that only the chocks 7 to 10 lying on this side can be seen.
  • the backup roll chocks 7 and 8 are guided in a window 11 of the roll stand 2.
  • a hydraulic adjusting device 13 is arranged between the upper crosshead 12 of the roller stand 2 and the chock 7 of the upper support roller 3.
  • the chock 8 of the lower support roller 4 is supported by a wedge adjusting device 14 against the lower crosshead 15 of the roller stand
  • cylinder blocks (Mae West blocks) 16 and 17, in which hydraulic cylinders 18 to 21 are installed for positive work roll bending.
  • additional hydraulic cylinders 22 are installed in the support roll chocks 7 and 8, which also act against the work roll chocks 9 and 10.
  • position sensors (not shown here) are installed in the hydraulic cylinders 18 to 21 in the cylinder blocks 16 and 17.
  • the installation of the position sensors in the hydraulic cylinders 18 to 21 prevents damage or contamination of the position sensors during the rolling operation.
  • FIG. 2 shows the work roll chock 9 with the work roll 5 mounted therein and the two hydraulic cylinders 18 and 19 in the cylinder blocks 16 and 17.
  • a position transmitter 24 and 25 is installed in each of the two hydraulic cylinders 18 and 19, a position transmitter 24 and 25 is installed.
  • the axis 26 of the work roll 5 lies in the middle between the two hydraulic cylinders 18 and 19, the distance between which is designated by x.
  • the points of attack of the hydraulic cylinders 18 and 19 on the work roll chock 9 are designated 27 and 28.
  • FIG. 3 illustrates the geometric relationships on the work roll chock 9.
  • the distance r between the axis 26 of the work roll 5 and the connecting line 29 between the two points of attack 27 and 28 of the hydraulic cylinders 18 and 19 on the chock 9 is designated by r.
  • the position transmitter supplies a position value s l and the position transmitter 25 supplies a position value s r .
  • a total of four such common position values s01, s02, s03 and s04 are determined, with the value s01 for the upper work roll 5 on the drive side and the value s02 on the operator side and the value s03 and the value for the lower work roll 6 on the drive side the value s04 is determined.
  • the block diagram in FIG. 4 shows a total of eight position transmitters 24, 25, 30, 31, 32, 33, 34 and 35, which are connected to an evaluation device 36.
  • the common position values s01 to s04 are calculated from the position values of two position sensors and added to the values h A and h B for the roll gap.
  • the values h A and h B only have to take into account the comparatively small influences from the work roll back bend, the work roll eccentricity, the thermal work roll expansion and the elastic deformation of the work roll chocks.
  • the previously required additional calculations of the suspension of the back-up rolls and the eccentricity of the back-up rolls can be omitted.
  • the direct detection of the roll gap according to the invention enables a significantly more precise roll gap control to be implemented.
