Definitions

  • the invention relates to a method for operating a rolling mill for hot and cold rolling of flat products in single or Multiple arrangement of the roll stands having two or more rolls with one, the differential rolling force between the drive and operator side of the rolling stands, with compensation for the bending and Balancing forces corrective control of the Nips.
  • the essential, the quality-determining requirements for this Method of rolling flat products, such as hot wide strip or Cold strip on tandem rolling mills or reversing mills is the after compliance with the strip flatness over the entire rolled strip length.
  • the prerequisite for fulfilling this requirement is Adherence to parallel roll gaps in all during the rolling process involved scaffolding that the geometric shape of the cross section determine the volume.
  • the invention is based on the knowledge that those without every horizontal shift occurring, the so-called. internal horizontal forces that need compensation. These inner ones Horizontal forces are created by a kind of screwing action on each other unroll rollers without axial relative movement.
  • the screwing motion is triggered by the entanglement of the rollers within the in the stand window of the roll stands, and the forces reach e.g. on scaffolding in hot-rolled strip finishing lines the order of magnitude 500 kN (approx. 50 t) with the disadvantage known to the rolling mill experts Effects on the parallelism of the roll gap.
  • the conversion in compensation values for the rolling force measurement in the column crossheads does differently than with the above methods, the Measurement of the axial forces on all rolls of the roll stand is necessary.
  • the invention has for its object the above Avoid disadvantages, especially the effect of the horizontal forces that occur on the uprights of the roll stands and those made from them to eliminate the resulting differential rolling force in the adjustment systems and ensure that there is also a change in the axial forces not change in size and direction during operation the differential rolling force between the drive side and the operator side leads.
  • This object is achieved in that the regulation before further processing of flat products on, off on all individual rollers measured additional horizontal corrective value is fed. You can do this by using the corrected Differential rolling force using the cross module for a swivel control, the roll gap contour, regardless of the Band position and the force distribution over the bandwidth can stay and continue according to the invention after a roll change for calibration, the compensated differential rolling force after stacking the rollers are regulated to zero.
  • the measurement of the forces in each Work rolls through, in the carrier of the rolls inserted force transducers and the measurement of the axial forces by measuring the hydraulic bridge done on such rollers that are pulled hydraulically are, if necessary. by actual force transducers in the bearing housing of Roller bearings are arranged.
