Definitions

  • the invention relates to a method for determining a springing of a rolling stand and / or edging stand during the machining of metal goods and a method for producing a metal good by means of a rolling stand and / or edging stand. Furthermore, the invention relates to a device for determining a springing of a rolling stand and / or edging stand.
  • the present invention is in the technical field of rolling mill technology.
  • Rolling mill technology is concerned with the production of metal products by rolling, which may be carried out in the form of cold forming or hot working.
  • the classical rolling in which the work rolls processing the rolling stock are arranged horizontally, are used.
  • the horizontal rolling is usually used to set a certain thickness of the metal. Also, thereby, e.g. during hot rolling, the mechanical properties of the metal to be processed are influenced.
  • the rolling process can be carried out, for example, as disposable rolls or reversing rolls.
  • the so-called upsetting is used, in which the work rolls are aligned vertically.
  • the upsetting causes an influence of the metal goods in the width direction by exerting appropriate forces.
  • the published patent application DE 101 39 513 A1 Means for determining, as required, a reference characteristic or a reference characteristic of a reversing rolling stand and / or means for determining a spring constant of a roll force-induced springing of the rolls or the entire system on a rolling stock. From these data, in turn, a rolling force-induced springing of the or each roll stand can be determined on the rolling stock.
  • a disadvantage of this method of determining the springing is that the force measurement or working pressure measurement is heavily spring-loaded. The characteristics often also include approximations, such as linearization, etc. Also lead to non-detectable, variable, directional friction forces in the rolling stand or edger to other Errors that additionally falsify the value for the springing determined by means of force measurement and / or working pressure measurement.
  • the object of the present invention is to provide a method for determining a springing of a roll stand and / or edging stand and a device for determining a springing of a rolling stand and / or edging stand, which make it possible to more accurately determine a springing of a rolling stand and / or edging stand.
  • a further object of the invention is to provide a method with which the quality of a metal product leaving the rolling stand and / or edging stand is increased.
  • a procedural part of the object is achieved by means of a method for determining a springing of a rolling stand and / or edging stand during the machining of metal goods, wherein at least two reference points for determining the springing are predetermined, wherein at least one of the reference points at a during the processing of the metal deforming scaffolding unit, in particular a scaffold stand, is arranged, and wherein a relative position of the at least two reference points to each other is determined during the processing of the metal good, and from this a springing of the rolling stand and / or edging stand is determined.
  • non-detectable, variable, direction-dependent frictional forces in the scaffolding unit are inherently taken into account by means of the method according to the invention. Because these do not contribute to the deformation of the scaffold unit, and thus also accordingly not included in the determination of the invention according to the invention. By this method, it is possible to realize a springing of a rolling stand and / or edger stand much easier and more accurate.
  • reference point is used in the context of this application in terms of a reference position, i. in the sense of location information, used.
  • the relative position is determined by measuring a distance of two reference points from each other.
  • the reference points are part of a measuring device for measuring a distance of the two reference points.
  • the measuring device can also be designed such that the at least two reference points are not part of a measuring device, so that they can be arranged almost arbitrarily. Thereby, if necessary, for each rolling mill, an individual solution - e.g. due to space issues - be provided.
  • the springing of the roll stand and / or edging stand is based on a comparison of a distance between the at least two reference points in a load-free state of the roll stand and / or edging stand and a distance of the at least two reference points in a loaded state of the roll stand and / or Stauchgerüsts determined.
  • a load-free state of the roll stand is usually present when no metal material is processed with this mill, ie the rolling stock is neither driven nor rolled.
  • the driving and / or rolling of a metal good should be regarded as a loaded state of a rolling stand. Analogously, this applies to a compression frame.
  • the at least two reference points are arranged on the scaffolding unit. Due to the arrangement of the at least two reference points on the scaffold unit, the springing can be detected in an improved manner.
  • a scaffolding unit may be, for example, a scaffold stand, or optionally also a housing, e.g. a stuffer. If necessary, this housing can simultaneously act as a scaffold stand.
  • the springback can be detected in an improved manner if the at least two reference points for a roll stand lie in vertical direction on two different sides of the roll gap.
  • the at least two reference points lie in the horizontal direction on two different sides of the compression region.
  • the at least two reference points are arranged on different sides with respect to a plane running parallel to the longitudinal axes of the work rolls or compression rolls-in the load-free state-through the roll gap or upset region, respectively.
  • the longitudinal extent of the framework stand is the direction in which the rolling stand or edger has the largest spatial dimension. By doing so, the length of the measurement path is increased, which in turn further increases the accuracy for determining the springback. It can be specified a plurality or plurality of reference points per rolling stand and / or edging stand, z. B. two to four per mill stand side, i. two to four each on the operating side and drive side of the rolling stand. All the above statements apply analogously to a compression frame.
  • the distance of the at least two reference points is determined contactless, in particular by means of a laser.
  • the laser light source forms a first reference point which is rigidly fastened to the rolling stand or upsetting frame, and a reflector which reflects the laser light, for example a mirror, a second reference point preferably also fixed rigidly to the rolling stand and / or edging stand.
  • the rigid attachment ensures that the reference points, which in this case are only indirectly connected to the roll stand, follow the deformation of the roll stand.
  • the distance between the at least two reference points is determined by contact.
  • this can be done with commercially available displacement sensors e.g. be realized by means of Sony-Weg sensors, Temposonic-way sensors, MTS-way sensors or other commercially available displacement sensors.
  • a two-part sensor is used, wherein both parts are firmly connected to the rolling mill stand and / or Stauchgerüstracr.
  • the two parts are movably coupled to each other in such a way that a relative movement of the two sensor parts to one another, in particular a change in the distance, can be detected.
  • the procedural part of the object is likewise achieved by a method for producing a metal good by means of a roll stand and / or edging stand, wherein a suspension of the rolling stand and / or edging stand caused by the metal goods passing through the rolling stand and / or edging stand is provided with a method according to one of the claims 1 to 5 is determined, wherein the thus determined springing, in particular online, is used to determine a manipulated variable for the roll stand and / or edger stand for influencing the rolling mill and / or edging mill continuous metal stock.
  • the production of the metal good can also be improved become. Because of the improved preliminary investigation for the springing up, this can be better compensated.
  • the manipulated variables determined from the springing-up for compensating the springing-up can be determined more accurately with regard to the rolled metal product, thereby increasing the quality of the metal product produced.
  • the device-related part of the object is achieved by means of a device for determining a springing of a rolling stand and / or edging stand, comprising a measuring device for detecting a distance between two reference points, wherein at least one of the reference points on a deforming during processing scaffold unit, in particular a rolling mill stand or Stauchgerüstracr is arranged, wherein the detected measured values corresponding signals of a signal processing means are fed, which is designed such that by means of this, the springing from the detected measured values can be determined.
  • the device according to the invention it is possible to realize a direct determination of the springing of a rolling stand and / or edging stand, whereby the accuracy for the determination of a springing can be significantly increased.
  • the resulting from the prior art disadvantages by an indirect determination of the spring-back are eliminated by the device according to the invention.
  • the at least two reference points are arranged on the scaffold unit, in particular on the rolling mill stand and / or on the swaging stand. This has the advantage that the springing can be determined very accurately.

  • the measuring device is as contactless working measuring device, in particular optically operating measuring device, or as contact-type measuring device for detecting the distance of the at least two reference points formed from each other.
  • the advantages for the non-contact measuring device are that there is a significantly lower wear of the measuring device compared to the contact-type measurement.
