Definitions

  • the invention relates to a rolling stand according to the preamble of claim 1 and a method for changing work rolls supported in the rolling stand according to the preambles of claims 7 and 9.
  • the rolling stand can be provided for use in cold or hot rolling plants.
  • the rolling stand can be, for example, a Mae-West stand.
  • the rolling stock is a metal profile or a metal strip.
  • the invention also relates to a new use for balancing cylinders supported on a rolling stand which normally serve to balance an upper support roll.
  • a roll stand in which the rolling stock can pass through the roll stand without hindrance during the roll change, is known from JP 2006 075857 A. Before the roll change a support from the drive-side chock of the lower
  • Working roll raised to raise the upper work roll with its chock and mount in an upper mounting rail The mounting rail extends continuously from the drive side to the operating side of the rolling stand and is firmly mounted on both sides.
  • the support is lowered again below the level of the rolling stock before the extension of the work rolls begins.
  • the upper and lower work rolls are then extended together across the rolling line from the rolling mill, while the rolling passes through the rolling mill.
  • the invention is based on the object, a generic rolling mill and
  • displacement in the sense of the invention not only means a movement of the mounting rail as a whole, for example by displacement or pivoting, but also “telescopic”. That is, a movement of the support rail out of itself, e.g. in the sense of extendable / extendable or collapsible / shortenable.
  • work roll preferably describes those rolls which are in direct contact with it for rolling a rolled product.
  • rolling line describes a distance along which the rolling stock is conveyed for rolling in the rolling direction.
  • the drive side describes the side of the rolling stand or the work rolls, on which drives are coupled to the work rolls.
  • the operating side is arranged opposite to the drive side and describes the side which is free of drives in order to be able to pull the work rolls for roll change out of the roll stand.
  • lower or upper mounting rail vertical displacement drive, balancing cylinder, carriage part, guide rail,
  • Support beams are used only in the singular, the respective statement basically refers both to the inlet side as well as on the outlet side component of said devices.
  • hold does not mean fixed, but only “held” contrary to gravity. A movement (the mounting rail) in particular in the horizontal or vertical direction is possible.
  • the upper support rail is advantageously stored virtually trouble-free.
  • the upper support rail formed in this way does not interfere with the operator-side roll stand, so that the rolling stand is always particularly accessible from the operating side.
  • the upper work roll can be changed even while a to be rolled
  • Walzgut is located in the rolling stand.
  • Such an "in-bar" roll change is very efficient, in particular, on a cast rolling mill which operates in a continuous operation, the present device for roll change of work rolls can be used advantageously, since in this case a continuous casting process for a roll change does not have to be interrupted.
  • the upper support rail can be designed to be so short, in particular with a corresponding design of the sledge part provided on the chock of the upper work roll, that it does not protrude into the rolling line or only negligibly. That the upper mounting rail - by pushing together or moving or
  • Pivoting - can be moved out of the range of the rolling line during the rolling process (retracted operating state), also has the advantage that this is not exposed to critical thermal stress during (hot) rolling or only to negligible extent.
  • the present device can be used very well on a hot rolling mill.
  • the upper support rails each have a sliding guide track, in which the drive-side chock of the upper
  • the carriage part is arranged at the far end of a cantilever arm of the drive-side chock of the upper work roll, the cantilever, projecting from the drive-side chock, preferably in the direction of the drive-side stand.
  • the upper work roll can correspond very well with the upper support rail. If the cantilever is arranged to extend parallel to the longitudinal extension of the upper work roll, the slide part can advantageously engage transversely in the upper support rail.
  • the upper support rails can be moved particularly space-saving, if they are arranged linearly displaceable on the drive-side stand of the rolling stand. Alternatively, however, they can also be made movable, for example, by pivoting out of the rolling line.
  • a drive device for example, an external change carriage, provided for horizontal displacement of the upper side
  • the upper support rail In a coupling of the upper work roll on their slide member with the upper support rail, the upper support rail can be moved horizontally with a horizontal displacement of the upper work roll.
  • the upper mounting rail must then have no own drive, in particular no own linear drive. Alternatively, however, its own drive for displacing the mounting rail or parts thereof may be provided.
  • the upper mounting rail is telescopic. As a result, the span of the upper mounting rail over the rolling line can be varied almost arbitrarily.
  • the upper mounting rail is telescopic.
  • the upper support rail can thus be moved completely out of the area of the rolling line, so that it can be well protected from thermal influences from the rolling line.
  • the upper support rail is horizontally telescoped so that it can span the rolling line at least as far as cantilevered in an extended state that the upper work roll at least partially supported by this upper support rail and can be reliably displaced transversely to the rolling line.
  • the vertical displaceability of the upper support rail can, for example, with the help of already existing mostly on a rolling stand Balancierzylinder as
  • the Balancierzylinder can be used immediately as a height adjustment of the upper support rail and beyond the upper work roll. This results in the advantage of large roll outlets very simple, without additional components, without interference edges of inner rails, etc.
  • the vertical displaceability of the upper support rail advantageously allows a contact between the upper support rail and in particular the chock of the upper work roll to be manipulated.
  • the upper work roll for a roll change can only be raised or lowered by the upper support rail. This makes it possible that the upper support rail preferably only comes into operative contact with the upper work roll or with their chock when a work roll change is present. Otherwise, the upper work roll can move vertically vertically during the actual rolling process.
  • the object of the invention is further achieved by a method according to claim 7 for removing an old roll from the rolling stand and by a method according to claim 9 for installing a new roll in the roll stand.
  • old work roll means a work roll to be replaced, in particular a used or worn work roll, while the term new work roll means an unused or at least retreaded work roll.
  • the advantages of the method correspond to the advantages mentioned above with reference to the roll stand.
  • the inventive method for removal of the old work rolls has the following steps:
  • the upper support rail - starting from the drive-side roll stand - along a transverse to the rolling direction alternating displacement cantilever shifts into the rolling line, before or while the old upper work roll - drive side mounted in the upper support rail - is moved out of a rolling stand out.
  • the extraction from the roll stand is typically carried out with an external pulling device, for example, a roll changing locomotive. Due to the drive-side connection between the work roll and the upper support rails, the upper support rails are also displaced into the rolling line when the work roll is withdrawn. For the active connection of the slide part of the old upper work roll in the upper mounting rails, the upper mounting rails using a

  • a vertical freedom of movement of the upper work roll during the actual rolling of a rolling stock can be easily maintained when the upper support rail is displaced only vertically, to make a contact-type engagement between one of the upper work roll associated slide member and the upper support rail. This means that the upper mounting rail with the guide rails only for
