  • the method according to the invention can be used for the entire rolling process, i. during threading, rolling and unthreading of the metal strip.
  • the lubricant is applied to the work roll such that the band center of the metal strip is approximated to a transport center axis of the transport region.
  • the transport center axis is usually the axis of symmetry of the rolling train in the transport direction of the metal strip. It can therefore be influenced by the application of lubricant, the tape layer so correct that the metal strip is optimally positioned for a rolling process.
  • the lubricant is applied to the work roll in the longitudinal direction of the work rolls with a variable amount.
  • different friction conditions can be set in a particularly simple manner over the width direction of the metal strip which allow control and / or control of tape travel.
  • lubricants could be used for different sections of the work roll in the longitudinal direction, which in turn could cause different friction conditions in the roll gap. These could then optionally be applied in a constant amount over the work roll in the longitudinal direction.
  • this is technically complicated and difficult to handle.
  • it requires a plurality of lubricants to be used.
  • different amounts of lubricant are applied to a drive-side half of the work roll and to an operating-side half of the work roll.
  • a setting engagement of a device for influencing the band position in order to control and / or regulate the band position, additionally a setting engagement of a device for influencing the band position, in particular of a roll stand, is used.
  • the band position in the rolling train can be adjusted by means of various technical contributions.
  • the flexibility of the method is increased because the limits of influencing the band position can be further extended by the combined influence of the band position.
  • any device can be used which is suitable for this purpose. In particular, rolling mills should be mentioned here.
  • the oblique position and / or the bending of the work rolls of the roll stand is used as an additional setting intervention.
  • the use of the skew and / or the bending of the work rolls can be particularly advantageous combined with the lubrication of the work rolls for adjusting the band position, as this combinatorial effect of employment of the rollers, in the sense of skew and / or bending, and lubricating the rollers results.
  • the friction conditions in the roll gap can be additionally varied and used for a correction of the band position.
  • the device-related part of the object is achieved by a control and / or regulating device for a rolling train, with a machine-readable program code which has control commands which, when executed, the control and / or regulating device for carrying out the method according to one of claims 1 to 6 cause.
  • the device-related part of the object is achieved by a generic rolling mill, in which a control and / or regulating device is provided according to claim 7, wherein the device for lubricating and the device for banding and optionally an additional device for influencing the band position, in particular a Roll stand, are operatively connected to the control and / or regulating device.
  • the operative connection of the additional device for influencing the band position with the control and / or regulating device is dependent on whether in addition a control intervention for adjusting the band position by means of this additional device is to be provided. If not, it is also not necessary to connect them to the control device according to claim 7 such that it is controllable and / or controllable with regard to the adjustment of the band position of the metal strip.
  • the control and / or regulating device according to claim 7 even more tasks, such as the implementation of Stitching plan by means of rolling mills, so the rolling mills are already effective connect with these reasons with the control and / or regulating device.
  • the lubrication device comprises a plurality of lubrication segments arranged in the longitudinal direction of the work rolls, by means of which lubricant can be applied to the work roll, wherein the delivery of lubricant can be individually controlled and / or regulated by means of the individual lubrication segments for each lubrication segment.
  • the object is likewise achieved by machine-readable program code for a control and / or regulating device for a rolling train, the program code comprising control commands which, when executed, cause the control and / or regulating device to carry out the method according to one of claims 1 to 6.
  • FIG. 1 shows a plan view of a section of a rolling mill 1. This section shows two rolling stands G1 and G2, wherein passes through the rolling stands G1 and G2 metal strip B and is thereby rolled.
  • the rolling stands G1 and G2 each comprise a pair of work rolls 3, wherein in each case only the upper work roll 3 of the respective rolling stand G1 or G2 in the illustration of FIG. 1 is visible. Any support rollers, stand stands, Anstellsysteme etc. are in FIG. 1 not shown, but available for processing the metal strip.
  • the metal strip B is transported along a transport region 2 through the rolling train.
  • the transport area 2 may comprise a roller conveyor or a loop lifter for the area of hot rolling.
  • the transport area 2 has a center axis M. This usually runs centrally through the rolling stands in the mass flow direction. Ideally, during the processing of the metal strip B, the center BM of the metal strip B coincides in the width direction with the transport center axis M. If the band center BM and the transport center axis M deviate from one another at any point along the rolling train, the band position for the rolling process is no longer optimal.

  • the control and / or regulating device 7 determines control signals for the lubricating device 4, in particular for the lubricating segments 5, and acts on the work rolls 3 with lubricant S in such a way that the belt running through the belt Rolling gap acting friction is changed so that the actual band position BM approaches a desired target band position for a subsequent mass flow direction transport section on the transport area 2.
  • the amount and / or distribution of the lubricant S in the longitudinal direction of the work rolls 3 in dependence on the drive side and operator side rolling force and / or employment and the rolling speed can be done with this framework.

  • a model is stored in the control and / or regulating device 7, which describes the friction conditions in connection with the forces acting in the transverse direction on the band B. Furthermore, the model takes into account the material flow in the nip, which also influences the strip run or the band position due to wedges and saber formation.
  • the lubricant distribution with respect to the transport center axis preferably takes place asymmetrically for the drive-side half AH and the service-side half BH of the work roll 3 or of the roll stand G1 or G2, depending on the direction in which the strip run is to be influenced.

From this view, it can be seen that for the respective work roll 3 above and below the transport level of the metal strip B, a lubricating device 4 exists, by means of which the friction conditions for top and bottom of the metal strip B can be set individually in the nip. This achieves the greatest possible degree of flexibility for adjusting the friction conditions in the roll gap.
