Definitions

  • the present invention relates to a rolling method for a metal strip, the Metal strip is rolled in at least one roll stand, with the metal strip, distributed over its width, a lot of lubricant is applied, as well as a corresponding roller arrangement.
  • Such rolling processes and rolling arrangements are known for example from DE 2 927 769 A1.
  • the object of the present invention is a rolling method and a to provide the corresponding roller arrangement by means of which even more reliable and planer belts can be produced.
  • the task is solved for the rolling process in that behind the rolling stand the temperature profile of the metal strip is determined over the metal strip width the temperature is measured by an infrared or a CCD camera the measured temperature is compared with a predetermined temperature: the place / places of the metal strip where the measured temperature is above the specified temperature, is / are determined and for adjustment the amount and / or distribution of the lubricant is used / become.
  • the lubrication process can be determined directly or indirectly.
  • the metal strip behind the roll stand has the width of the metal strip a temperature curve.
  • This temperature profile can - for example using an infrared or CCD camera - be recorded and from the temperature profile then (indirectly) the lubrication process can be determined.
  • the lubrication process can directly.
  • B. due to a surface condition of the metal strip behind the roll stand can be determined.
  • the surface texture of the metal strip can, for example, optically on a or be recorded on both sides of the tape.
  • the rolling process works more comfortably if the information about the Lubrication curve is output to a controller and the controller's setting the amount and / or the distribution of the lubricant and / or the performs at least one rolling parameter.
  • Lubrication is deficient only locally, is preferably also only locally on the Lubrication conditions influenced. This is usually done by that changes the defects and / or the distribution of the lubricant becomes.
  • systematic lack of lubrication e.g. B. Lack of lubrication at both ends of the band across the metal band width, can e.g. B. influenced the roll bending of the work roll become.
  • other rolling parameters can also be influenced.
  • the change in the amount and distribution of the lubricant can e.g. B. done in such a way that the lubricating device is a basic lubricating device and has an additional lubrication device and the amount and distribution of constant lubricant to be applied by the basic lubrication device the amount and / or distribution of that to be applied by the additional lubrication device Lubricant is adjustable.
  • the rolling plan calculator learns after and according to what lubricant quantities and distributions for certain metal strips or pass schedules are required.
  • the metal strip can consist of different metals, for example Steel, copper, aluminum or brass.
  • a metal strip 1 is rolled into one at a rolling speed v Roll stand 2 rolled with work rolls 3.
  • the roll stand 2 is according to FIG. 1 designed as a two-roll mill stand. So it only shows the work rolls 3 on.
  • the roll stand 2 could also support rolls, if necessary also intermediate rolls, shifting systems in one or more of the roll planes etc. or z. B. as a so-called rolling mill stand be trained.
  • the metal strip 1 has a metal strip width b.
  • the embodiment consists of the metal strip 1 made of steel. But it could also made of another metal, e.g. B. copper, aluminum or brass.
  • a lubrication device 4 is assigned to the roll stand 2. According to Figure 1 arranged in front of the roll stand 2. By means of the lubrication device 4 an amount of lubricant 5 (e.g. an oil-water mixture) over the metal bandwidth b distributed on the metal strip 1 from above and below.
  • the Lubrication device 4 has a basic lubrication device 4 'and an additional lubrication device 4 "on. The amount and distribution of that from the basic lubricator 4 'is to be applied lubricant 5 - at least during of a stitch - constant. The amount and / or distribution of the of the Additional lubrication device 4 "to be applied lubricant 5, however adjustable.
  • the metal strip 1 has behind the roll stand 2 over the metal strip width b a temperature curve.
  • the roll stand 2 is therefore a temperature profile detection device 6 subordinate.
  • the temperature runout detection device 6 is designed, for example, as an infrared camera.
  • the Temperature profile detection device 6 is the temperature profile of the Metal strip 1 cyclically behind the roll stand 2 over the metal strip width b detected.
  • the lubrication curve is then determined from the temperature curve or inferred about possible stability problems in the roll gap.
  • the temperature profile detection device 6 thus serves as a lubrication course detection device 6th
  • the temperature profile detection device 6 can be designed in various ways his. Instead of an infrared camera, for example, there is also a CCD camera or a sensor array in question. In any case, the temperature profile detection device should 6 arranged as close as possible to the roll stand 2 his. The distance should be a maximum of 5 m to 10 m.
  • the lubrication course detection device 6 with a controller 7 connected.
  • the controller 7 is in turn with the lubrication device 4 and / or the roll stand 2 connected by control technology. Due to the recorded temperature or lubrication course, the controller 7 can adjust the setting Amount and / or the distribution of the lubricant 5 and / or at least one Rolling parameters, e.g. B. the rolling speed v, make.
  • the lubrication course detection device 6 is also connected to a controller 7 Rolling plan computer 8 connected.
  • the rolling schedule computer 8 is the controller 7 superior.
  • An adaptive rolling model is implemented in it. So can adjusting the amount and / or distribution of the lubricant 5 and / or at least one rolling parameter, e.g. B. the rolling speed v, can also be transmitted to the rolling schedule computer 8.
  • the rolling schedule calculator 8 is able to adapt the rolling model implemented in it, so that with a newly rolled metal strip 1 better presettings made can be.
  • the lubrication course detection device 6 is also included an output device 9 connected.
  • the output device 9 is, for example a monitor, through which information about the lubrication process an operator 10 is issued for the roll stand 2.
  • Figure 2 are three different, to the minimum temperature across the Metal bandwidth b normalized temperature profiles A, B, C shown. Furthermore is a dashed line drawn in which corresponds to a temperature which is above the minimum temperature by a predetermined percentage. The percentage is typically between 5% and 10%.
  • Figure 3 corresponds essentially to Figure 1. It is particularly clear from Figure 3 can be seen that the lubricant 5 both from above and from below the metal strip 1 is applied. In contrast to the embodiment 1, however, there is no controller 7. Setting the crowd and / or the distribution of the lubricant and / or the at least one Rolling parameters are therefore carried out by the operator 10 according to FIG. 3.
  • the rolling process can be used in all rolling processes. Especially but it is advantageously used when the metal strip 1 is cold-rolled is, the rolling arrangement is designed as a cold rolling arrangement.
