Definitions

  • the present invention is based on a storage device for two similar rolls of a roll stand, the storage device being part of the roll stand or being positionable relative to the roll stand in such a way that the rolls can be transferred from the roll stand to the storage device or vice versa.
  • the roll gap is usually calculated as part of the so-called level 2 automation.
  • Complex models are used to calculate the roll gap, which for example the Roll adjustment, roll bending, roll flattening, roll crowning, roll wear, roll temperature, the temperature of the rolled stock and more.
  • Some of the sizes mentioned are given as the respective course over the roll barrel width.
  • a roller is local (the term “local” refers to the location viewed in the direction of the roller axis), the thicker the higher the temperature of the roller at the respective location. Conversely, the roller is locally thinner, the higher the wear or abrasion of the roller at the respective point.
  • the absolute accuracy with which the roll gap must be calculated is greater, the smaller the roll gap is.
  • a roll gap of - for example - 3 cm an accuracy of 20 ⁇ m or 50 ⁇ m may be perfectly acceptable. In the case of a roll gap of - for example - 1.2 mm, however, such an accuracy is generally no longer acceptable.
  • the roll gap is influenced, among other things, by the local temperature of the rolls. Furthermore, the roll gap is also influenced by the abrasion to which the rolls are subjected during operation. In addition, the material temperature of the flat rolled stock also depends, within certain limits, on the temperature, in particular of the work rolls. The temperature of the rolling stock is, in turn, an important criterion for correctly determining the rolling force, for example. This applies to both hot rolling and cold rolling.
  • the object of the present invention is to create possibilities by means of which a roll model, by means of which the temperatures of rolls and their wear and thus their diameter can be determined spatially resolved in the direction of the roll axes, can be optimized in a simple and reliable manner.
  • a bearing device of the type mentioned at the outset is designed in that the bearing device has at least one measuring system, by means of which the temperatures and / or the diameter of the rollers, viewed in the direction of the roller axes, can be recorded individually and independently of one another at least at predefined recording positions.
  • the actual temperatures and / or the actual diameters of the rollers can be recorded using measurement technology, so that they can be compared with the corresponding values determined with the aid of a model and the roller model can be adapted based on the comparison.
  • the storage device is part of the roll stand.
  • this configuration only makes sense in a special configuration.
  • the storage device is designed as a roll changing carriage. In this case, it can be ensured in a particularly simple manner that the measuring system is not exposed to the rough operation of the roll stand, as occurs when the flat rolled stock is rolled.
  • the measuring system per roller it is possible for the measuring system per roller to have several measuring devices that are stationary with respect to a base body of the bearing device, so that by means of the measuring devices the temperature and / or the diameter of the respective roller, viewed in the direction of the roller axes, can be detected at one of the predefined detection positions.
  • a measuring device can be provided every 10 cm or every 20 cm, by means of which the temperature and / or the diameter of the respective roll can be detected at the respective point.
  • the measuring system it is possible for the measuring system to have several measuring devices per roller, which are movable in the direction of the roller axes with respect to a base body of the bearing device are, so that by means of the measuring devices the temperature and / or the diameter of the respective roll viewed in the direction of the roll axes can be detected in a respective sub-section comprising at least one of the predefined detection positions.
  • the measuring devices can be displaceable by 5 cm, 8 cm, 12 cm or 15 cm to the left and right as viewed in the direction of the roller axes.
  • the temperature and / or the diameter of the respective roller in a respective sub-area of 10 cm, 16 cm, 24 cm or 30 cm can be recorded by means of one of the measuring devices.
  • the numerical values mentioned are purely exemplary.
  • the sub-areas can overlap or be disjoint from one another.
  • the measuring system it is possible for the measuring system to have a single measuring device for each roll, by means of which the temperatures and / or the diameter of the respective roll can be detected, viewed in the direction of the roll axes, at least at all of the predefined detection positions.
  • This embodiment has the advantage that only a minimal number of measuring devices is required.
  • the measuring device it is possible for the measuring device to be arranged movably on a base body of the bearing device, viewed in the direction of the roll axes, so that the measuring device can be moved over the entire effective barrel length of the rolls.
  • the rollers are first arranged in the base body of the bearing device. Then the measuring device is moved along the rollers. During this traversing movement, which may be interrupted again and again for a single measurement process, the temperatures and / or the diameter of the rollers are recorded.
  • the measuring device it is possible for the measuring device to be arranged in a stationary manner on a base body of the bearing device in such a way that the respective roll is moved past the measuring device when it is transferred from the roll stand to a roll changing carriage or vice versa.
  • This configuration is particularly simple, since no further moving parts are required beyond those parts that have to be present anyway for transferring the rolls from the roll stand to the roll changing carriage or vice versa.
  • this embodiment can specifically be implemented not only with a roll changing carriage, but also with a roll stand itself.
  • the measuring device can in this case be arranged in a protected area of the stand upright on the operator's side.
  • the recorded measured values can be fed manually to an automation unit that controls the rolling stand.
  • the measuring system is connected to this automation unit in terms of data technology and automatically transmits the recorded temperatures and / or diameters to the automation unit, so that the recorded temperatures and / or diameters can be assigned to the predefined detection positions by the automation unit.
  • the detection positions are also transmitted to the automation unit.
  • a flat rolling stock 1 made of metal passes through roll stands 2 of a rolling train and is thereby rolled.
  • the rolling takes place in each case between two similar rolls 3 of the respective roll stand 2.
  • the flat rolling stock 1 can be a strip or a heavy plate.
  • the metal from which the flat rolling stock 1 is made can be steel or aluminum, for example.
  • the present invention is particularly advantageously applicable when the rolling is cold rolling.
  • the two rolls 3 of the same type are generally the two work rolls of the respective roll stand 2, that is to say those rolls which act directly and directly on the flat rolling stock 1.
  • rollers 3 can be rolls that act directly or indirectly on the work rolls, for example in the case of a four-high stand or a six-high stand around the back-up rolls or in a six-high stand around the intermediate rolls arranged between the back-up rolls and the work rolls.
  • the rollers 3 are similar in the sense that they are functionally similar and one of the two rollers 3 acts on the rolling stock 1 from above and the other from below.
  • the rolling train is controlled by an automation unit 4.
  • the automation unit 4 thus also controls the roll stands 2.
  • the control of one of the roll stands 2 by the automation unit 4 is explained in more detail. It is pointed out in advance that that this type of control is generally known as such to those skilled in the art. Details on the specific implementation are therefore not required.
  • the automation unit 4 implements a roll model 5.
  • the automation unit 4 supplies the roll model 5 with operating data BD of the roll stand 2.
  • the operating data BD generally include actual properties of the flat rolling stock 1 as it enters the roll stand 2, such as, for example, its width, its thickness, its chemical composition and its temperature.
  • the operating data BD generally also include target properties of the flat rolling stock 1 as it exits from the roll stand 2, such as, for example, its thickness together with the associated profile, associated contour and / or associated flatness.
  • the automation unit 4 continues to apply, even if only temporarily, control data SD for the roll stand 2.
  • the control data SD are also fed to the roller model 5.
  • the control data SD can include, for example, the pitch, the rolling force, a bending force and others.
  • the control device determines the temperature T of the respective roll 3 and / or the diameter D of the respective roll 3 for the two identical rolls 3 when leaving the roll stand 2.
  • the determination is carried out in all cases, viewed in the direction of the roll axes, spatially resolved. So it takes place at least at predefined determination positions p.
  • the in FIG 2 the distance of 20 cm between adjacent determination positions p is only to be understood as a purely exemplary one.
  • the automation unit 4 compares the expected actual properties of the flat rolling stock 1 determined by means of the rolling model 5 as it exits the roll stand 2 with the desired target properties of the flat rolling stock 1 when it exits the roll stand 2.
  • the automation unit 4 then varies as necessary the tax data SD, in order to approximate the expected actual properties of the flat rolled stock 1 as it exits the roll stand 2 as closely as possible to the desired target properties of the flat rolled stock 1 as it leaves the roll stand 2. If necessary, an iterative approach is used. Varying the control data SD is in FIG 2 indicated by the fact that the operating data BD are fed to the roller model 5 exclusively from the automation unit 4, while the control data SD can be transmitted in both directions.
  • the procedure explained is generally known and familiar as such to those skilled in the art. It is repeated over and over again when the flat rolling stock 1 is rolled, for example for a new section of the flat rolling stock 1 or for a subsequent flat rolling stock 1.
  • the automation unit 4 determines again and again (spatially resolved, among other things, as seen in the direction of the roll axes) the temperatures T and / or the diameter D of the rolls 3 and, based on this, the respective control SD of the roll stand 2, that is to say the control data SD.

  • the rollers 3 can be dismantled and transferred to the roller changing carriage 6 of the rollers 3 in a conventional, generally known manner. What is important, however, is that the temperatures T and / or the diameter D of the two rolls 3 are recorded during the removal of the rolls 3 from the roll stand 2 and the transfer of the rolls 3 to the roll changing carriage 6 or immediately thereafter. The detection therefore takes place before the roll changing carriage 6 is removed from the roll stand 2.
  • the detection takes place in an automated manner by means of a measuring system 7 which is arranged on the roll stand 2 or on the roll changing carriage 6. Furthermore, when viewed in the direction of the roller axes, the detection takes place in a spatially resolved manner, namely at least at predefined detection positions p '.
