Definitions

  • the present invention relates to a device for lateral guidance of a running between two stands of a finishing train with different paths over a variable in various positions loop loom metal belt.
  • loop lifters are installed between the rolling stands in the finishing mill. This is essentially a role whose horizontal axis of rotation is vertically adjustable.
  • the metal strip is tensioned and guided over the looper roll - also called looper roll - if its surface lies above the pass line of the finishing train.
  • the looper roll is moved out of the pass-line upwards, depending on the force generated by the metal strip on the looper roll.
  • the metal strip is for example a steel strip or an aluminum strip.
  • the main body module with guide level for example, a so-called guide ruler, which has a suitable surface for guiding the metal strip, the guide level.
  • the lateral guidance device may comprise a base body module or a plurality of base body modules.
  • the guide level is used for lateral guidance of the metal strip by means of contact with the sides of the metal strip. It limits the freedom of movement of the metal strip in their direction, whereby the metal strip is guided laterally.
  • the management level is essentially vertical.
  • the device for lateral guidance also includes a plurality of wear bodies with a wear surface.
  • a wear body is a body that is subject to wear due to the guidance of the metal strip, at a region called the wear surface.
  • the wear body is a different component than the main body module, but can be inserted into the main body module or attached to it.
  • the wear body has at least one wear surface; this is turned towards the metal strip when the metal strip is guided and wears due to contact with the metal strip in the course of the lateral guidance of the metal strip. The metal strip cuts into the wear body and thus wears it.
  • the wear surface is essentially flat in the unworn state.
  • the wear surface is the area of the wear body that is provided in operation for the guidance of the metal strip.
  • the so-called wear body can also have areas that will not come into contact with the metal strip during operation, for example due to their removal from the pass line of the finishing train.
  • the wear body may be round or have other contours.
  • the wear body is rotatable in several rotational positions. He can therefore take at least two rotational positions, between which the operator can select and control the rotation and / or regulate accordingly. It is included with that of Wear body sequentially takes a variety of rotational positions while it is rotated.
  • the wear body can be fixed in a desired rotational position, which it has achieved by turning, or be rotated by further rotation in a further rotational position.
  • the rotation can also be very slow, for example, a revolution in 12 hours; In the 12 hours a variety of rotational positions are taken successively.
  • a looper is available between two rolling mills of the finishing train.
  • the area of the wear surface of adjacent wear bodies increases in the direction of the loop lifter.
  • the wear body directly adjacent to the rolling stand has the smallest area of the three wear bodies, and the wear body directly adjacent to the loop lifter has the greatest area.
  • the central wear body has a larger area than its neighbor, which is directly adjacent to the rolling stand; and a smaller area than its neighbor, which is directly adjacent to the loop lifter.
  • the looper is - for example, pressure or force controlled - adjustable in different positions and is in operation of the finishing train depending on the properties of the metal strip in different positions.
  • For each position of the loop lifter results in another path for the metal strip between a rolling mill and the directly adjacent looper; it is different in each case the Bandeinlauf- or belt outlet angle.
  • Bandeinlauf- or belt outlet angle refer to the plane in which the roll nips of the two rolling stands are; from the nip of the first rolling mill seen in the strip running direction, the metal strip exits and runs its path in the direction of the nearest scaffold on the Schstedheberrolle, where it deflects. From there it runs into the nip of the Tape running direction seen second rolling stand a.
  • a wear body is rotatable about an axis of rotation.
  • the wear body may be rotated about the axis of rotation, thereby turning another portion of the edge of the metal band and being worn therethrough.
  • the need for replacement of the wear surface or the wear body can be delayed, as always other areas of the edge of the metal strip are facing and therefore the wear evenly distributed over the wear surface.
  • the cost of replacing worn parts is reduced, since less frequent replacement is necessary. It can also help to ensure that packs do not accumulate in one place. Accordingly, the risk of falling on the metal strip is reduced.
  • existing packages may optionally be ground off the metal strip at a different rotational position of the wear body.
  • the wear bodies are interchangeable, so that when excessive wear of these components can be easily replaced.
  • a more complex replacement of the main body modules -rankmap parts of the main body modules such as wear plates - is less often necessary, since the lateral guidance is sufficient even by the wear body alone. Since the wear bodies can be rotated in different rotational positions, a new area of the wear surfaces can always be worn out, whereby the wear is distributed can and replacement is less necessary. This saves effort and costs in the maintenance of the device for lateral guidance.
  • At least one wear body can be arranged in a recess of the at least one main body module. If the at least one wear body is arranged in a recess of the at least one main body module, it is possible to perform a simultaneous guidance of the metal strip by the main body module and the wear body - for example, if the wear surface of the wear body does not protrude beyond the management level of the main body module, but at least partially you are lying. If the wear surface as claimed in the invention is substantially planar and parallel to the guide plane, this may be the case, because parallel to the guide plane also comprises in a plane with the guide plane.
  • the recess is round. This allows easy rotation of a arranged in this recess wear body when it is rotationally symmetrical or rotationally symmetrical with respect to its axis of rotation. If the recess is not completely enclosed by the base body module, in this embodiment the edge of the recess in the base body module follows a part of a circle.
  • the recess may also have other shapes.
  • the wear bodies are preferably arranged such that each travel path leads over each wear surface. For every running path, it therefore applies that it lies partly on each of the wear plates between the rolling stand and the loop lifter - regardless of the distance from the pass-line to the loop lifter roller, all wear bodies then contribute to the lateral guidance.
  • Another object of the present application is a method for operating a device according to the invention characterized in that at least one of the wear bodies is rotated while the metal belt is running. During rotation, he takes a variety of rotational positions. The rotation can also be done very slowly, for example, a revolution in 12 hours. The rotation can also be interrupted by pauses. By turning the wear of the wear body can be evenly distributed over the wear surface, which helps to extend the replacement intervals. The turning can be like in WO2015043926A1 done in defined rotational positions; It can also be done in undefined rotational position with respect to the axis of rotation in the sense that is not predetermined by the operator that at a certain time a certain rotational position is to be taken.
  • lateral guidance takes place on each runway through each wear body.
  • FIG. 1 shows a side view fragmentary, as in a conventional device, a metal strip 1 runs in the direction indicated by an arrow between two rolling stands 2,3 a finishing train via a loop 4.
  • plate-shaped wear strips 5a, 5b are present on the right and left of the loop lifter 4.
  • the loop 4 is adjustable in various positions, which is represented by a double arrow.
  • the metal strip 1 follows another path from the nip 6 of the first rolling stand 2 in the strip running direction into the nip 7 of the second rolling stand 3 in the direction of strip travel. Only the path belonging to the illustrated position of the loop lifter 4 is shown.
  • FIG. 2 shows a section of an embodiment of a device according to the invention for the lateral guidance of a rolling mill between 8.9 a finishing train with different running paths 10,11 via an adjustable in different positions looper 12 metal strip 13 in a lateral view.
  • the running direction of the metal strip is shown by an arrow.
  • Shown is a main body module 14 with a substantially vertical guide plane 15 which is arranged between the last in the strip running direction rolling mill 8 and the loop lifter 12.
  • the looper 12, over which the metal strip 13 passes, can be set in various positions; this is illustrated for two positions of the loop lifter roller with closed outline 16 and dashed outline 17.
  • the device also includes three wear bodies rotatable in multiple rotational positions 18,19,20, wherein the wear surfaces 21,22,23 of the wear body 18,19,20 are substantially flat and in all rotational positions parallel to the guide plane 15 of the main body module 14.
  • the three wear bodies 18, 19, 20 are arranged between the last rolling stand 8 and the loop lifter 12, as viewed in the direction of travel of the strip. Seen from the roll gap 24 in the direction of the loop lifter 12, the surface of the wear surface 21, 22, 23 of adjacent wear bodies 18, 19, 20 increases, since the diameters of the three round wear bodies 18, 19, 20 increase.
  • each travel path leads over each wear surface 21, 22, 23.
  • the Schl constitution stresses 18,19,20 are rotated - represented by curved arrows, different directions of rotation are possible - while the metal strip 13 is running.
  • the looper 12 and roll stand 9 optionally existing parts for lateral guidance is omitted for reasons of clarity; it may, for example, be a mirror-inverted arrangement to the arrangement shown.
