Definitions

  • the present invention is based on a bearing device for two identical rolls of a roll stand, the bearing 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 bearing device or vice versa.
  • a generic device is off DE 101 38 588 A1 known.
  • 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, roll adjustment, roll deflection, roll flattening, roll crowning, roll wear, roll temperature, temperature of the rolling stock and others.
  • Some of the variables mentioned are specified as a respective progression over the width of the roll barrel. For example, a roll is locally (the term “locally” refers to the location seen in the direction of the roll axis) thicker, the higher the temperature of the roll at the respective location. Conversely, the roller is thinner locally, the higher the wear or abrasion of the roller at the respective location.
  • a roll gap of - for example - 3 cm an accuracy of 20 ⁇ m or 50 ⁇ m may well be acceptable.
  • a roll gap of - for example - 1.2 mm 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 rolling stock also depends, within certain limits, on the temperature of the work rolls in particular. In turn, the temperature of the rolling stock is an important criterion, for example for the correct determination of the rolling force. 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 in a spatially resolved manner viewed 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 diameters of the rolls, seen in the direction of the roll axes, can be detected individually and independently of one another at least at predefined detection positions.
  • the actual temperatures and/or the actual diameters of the rolls can be measured, so that they can be compared with the corresponding values determined with the aid of a model, and the roll model can be adapted based on the comparison.
  • 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 rolling the flat rolled stock.
  • the measuring system per roll it is possible for the measuring system per roll to have several measuring devices that are stationary with respect to a base body of the bearing device, so that the temperature and/or the diameter of the respective roll, seen in the direction of the roll axes, can be detected at one of the predefined detection positions by means of the measuring devices.
  • a measuring device viewed in the direction of the roll axes, for example, 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 recorded at the respective point.
  • the measuring system it is possible for the measuring system to have a plurality of measuring devices per roll, which can be moved in the direction of the roll axes with respect to a base body of the bearing device are, so that the temperature and/or the diameter of the respective roll, seen in the direction of the roll axes, can be detected by means of the measuring devices in a respective section comprising at least one of the predefined detection positions.
  • the measuring devices can be moved to the left and right by 5 cm, 8 cm, 12 cm or 15 cm, starting from a central position of the respective measuring device, viewed in the direction of the roller axes.
  • the temperature and/or the diameter of the respective roll can be recorded in a respective partial area of 10 cm, 16 cm, 24 cm or 30 cm by means of one of the measuring devices.
  • the numerical values mentioned are purely exemplary.
  • the partial areas can overlap or be disjunctive to one another.
  • the measuring system it is again possible for the measuring system to have a single measuring device for each roll, by means of which the temperatures and/or the diameters of the respective roll, seen in the direction of the roll axes, can be detected at least at all of the predefined detection positions.
  • This configuration has the advantage that only a minimum number of measuring devices is required.
  • the measuring device it is possible for the measuring device to be arranged on a base body of the bearing device so that it can be moved 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 initially arranged in the base body of the bearing device. Then the measuring device is moved along the rollers. The temperatures and/or the diameters of the rolls are recorded during this travel movement, which may be interrupted again and again for a single measurement process.
  • the measuring device is arranged stationary on a base body of the storage device such that the respective roll is moved past the measuring device during transfer from the roll stand to a roll changing carriage or vice versa.
  • This configuration is particularly simple, since no other moving parts are required beyond those parts which must be present anyway for transferring the rolls from the roll stand to the roll-changing carriage or vice versa.
  • this configuration can be implemented not only in a roll changing carriage, but also in a roll stand itself.
  • the measuring device can be arranged in a protected area of the stand on the operator side in this case.
  • the recorded measurement values can be fed manually to an automation unit that controls the roll stand.
  • the measuring system is preferably 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 recording positions by the automation unit. It may be necessary for this purpose for the detection positions to be transmitted to the automation unit in addition to the temperatures and/or diameters.
  • FIG 1 passes through a flat rolling stock 1 made of metal roll stands 2 of a rolling train and is thereby rolled.
  • the rolling takes place between two identical rolls 3 of the respective roll stand 2.

  • the automation unit 4 compares the expected actual properties of the flat rolling stock 1 determined by means of the rolling model 5 when leaving the rolling stand 2 with the desired target properties of the flat rolling stock 1 when leaving the rolling stand 2. If necessary, the automation unit 4 then varies the tax data SD, in order to approximate the expected actual properties of the flat rolling stock 1 when leaving the rolling stand 2 as closely as possible to the desired target properties of the flat rolling stock 1 when leaving the rolling stand 2. If necessary, an iterative procedure is used. Varying the control data SD is in FIG 2 indicated by the fact that the operating data BD are supplied to the roller model 5 exclusively by the automation unit 4, while the control data SD can be transmitted in both directions.
  • the procedure explained is generally known and familiar to those skilled in the art. It is carried out again and again during the rolling of the flat rolling stock 1, 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 the result (among other things and spatially resolved as seen in the direction of the roll axes) again and again the temperatures T and/or the diameters D of the rolls 3 and, based on this, the respective activation SD of the roll stand 2, ie the control data SD.
