Definitions

  • the invention concerns a device for bending the rolls in a rolling stand comprising several rolls with the use of bending blocks, which are mounted at the run-in end and the runout end between the roll chocks and the housing windows and can be acted upon by control elements.
  • Devices of this general type are used for flatness control of a rolled product as control elements for bending the work rolls.
  • the control element has a direct effect on the roll gap geometry in the strip edge region, such that the work rolls are bent positively around the edge of the rolls lying above them and negatively around the edges of the rolling stock.
  • the goal of the invention is to reduce frictional forces in a system of this general type.
  • a piston-cylinder be assigned to the bending blocks of one of the mill housings, and that a vertical positioning mechanism be assigned to the bending blocks of the opposite mill housing.
  • the positioning and locking of the bending blocks by means of the vertical positioning mechanism make it possible to produce a center of rotation about which the chock can be rotated.
  • the vertical positioning mechanism preferably a spindle-type lifting gear unit
  • the worn zone of the rolls can also be compensated by the spindle-type lifting gear unit.
  • the device of the invention can also be used for intermediate roll bending in a six-high mill. Use in reversing mills is also conceivable.
  • FIG. 1 shows a side view section of a four-high mill from the drive end.
  • FIG. 2 shows a top view of the work roll plane of the rolling stand in FIG. 1 .
  • a rolling stand 1 the work rolls 3 , 3 a are supported by the backup rolls 2 , 2 a .
  • the chocks 4 , 4 a of the work rolls are connected by the bending blocks 5 , 5 a , 5 ′, 5 a ′ with the mill housings 6 , 6 ′.
  • a spindle-type lifting gear unit 10 is installed between the bending blocks 5 ′ and 5 a ′ and can be positioned and locked by a drive 12 .
  • the bending blocks 5 and 5 a are connected by a piston-cylinder 7 , whose piston 9 is supported in bending block 5 a , while its connecting rod 8 is mounted in bending block 5 .
  • the bending blocks 5 , 5 a , 5 ′ and 5 a ′ can be connected by well-known means with the chocks 4 , 4 a of the work rolls 3 , 3 a , on the one hand, and the mill housings 6 , 6 ′, on the other hand.
  • the rolling direction of the rolling stock passing through the mill is indicated by the double arrow 11 .
  • Flatness control is accomplished by positioning and locking the bending blocks 5 ′, 5 a ′ with the spindle-type lifting gear unit, while the piston-cylinder 7 , which connects the bending blocks 5 and 5 a with each other, introduces the necessary bending force.
  • the invention is not limited to the use of spindle-type lifting gear units, but rather any vertical positioning mechanism can be used, for example, wedges with restricted guidance, a cylinder with clamping head and position sensor, or an eccentric shaft.
