Definitions

  • the invention relates to a method for opening and/or closing a roll stand during rolling, in particular hot rolling, of a rolled product.
  • the invention further relates to a rolling stand and a device for rolling a rolled product.
  • a roll stand has at least two work rolls aligned in parallel, which form a roll gap through which the rolled product usually passes for the purpose of reducing the thickness.
  • the relative position of the work rolls for adjusting the roll gap can be varied, for example, by hydraulically adjusting one or both work rolls.
  • the rolled product is conveyed through an open roll stand without the work rolls exerting a forming force on the rolled product. Only after a certain time or a certain strip length is the rolling stand closed in order to begin or continue the actual rolling process. For example, during a flying roll change in a casting-rolling plant or a tandem rolling mill, the roll gap of the roll stand is first opened, whereby the reduction in thickness on this roll stand is reduced to zero in order to enable a roll change. After the roll change, the roll gap is closed.
  • the DE 34 13 424 A1 , JP S59 189012 A , JP S59 85314 A and DE 10 2005 051 053 A1 describe methods and devices for controlling the lateral unstable movement of a strip undergoing a rolling process.
  • One object of the invention is to provide an improved concept for opening and closing a rolling stand, in particular to improve the reliability of the rolling process.
  • the method, the rolling stand and the device are used in particular in a rolling mill for rolling a rolled product made of metal, preferably made of steel or a non-ferrous metal.
  • the rolled product is preferably a metal strip, in particular a hot strip.
  • the method according to the invention relates to opening and/or closing a roll stand with at least two work rolls forming a roll gap.
  • the rolled product is transported through the roll gap along a conveying direction for forming. At least one of the two work rolls is in the
  • the plane can be moved perpendicular to the conveying direction in such a way that not only the roll gap can be increased and decreased, but also that the position of the work roll relative to the rolled product can be varied.
  • the "position” here refers to the degree of inclination of the work roll in the said plane relative to the other work roll or to the strip plane, provided that the rolled product is strip-shaped.
  • the rolled product is transported through the roll gap along the conveying direction, and during this time the roll stand is opened or closed by correspondingly increasing or decreasing the roll gap.
  • the work rolls - in contrast to the closed state - preferably exert no rolling force on the rolled product, at most a small one.
  • a position of the rolled product in front of and/or behind the roll gap in the direction transverse to the conveying direction, i.e. in the axial direction of the work rolls, is detected.
  • the terms “before” and “behind” are defined relative to the conveying direction of the rolled product.
  • the position of the corresponding work roll is changed so that the rolled product is held or stabilized at a target position during the opening and closing of the rolling stand.
  • the position of both work rolls can also be changed for this purpose.
  • the roll gap or its geometric shape is therefore regulated during the opening or closing of the rolling stand in such a way that the rolled product does not run away to the side, but is kept close to a target position.
  • the process of opening and closing the roll stand is stabilized while the rolled product is conveyed at the same time, which improves the quality of production and minimizes any waste.
  • particularly efficient production is possible because, for example, a flying It is possible to change rolls during ongoing production without the risk of interrupting production or loss of quality due to incorrect placement of the rolled product in the roll gap.
  • position and “location” are used interchangeably with respect to the placement of the rolled product in the roll gap in the transverse direction.
  • the position of the rolled product is detected without contact, which means that no unnecessary forces act on the rolled product to carry out the method and the reliability of the corresponding detectors is also increased, since they are subject to little or no wear.
  • the position of the rolled product is detected, for example, optically, preferably using one or more cameras, using radar or laser scanning.
  • existing systems can be retrofitted in a mechanically simple and reliable way.
  • a physical parameter can be used that indirectly reflects the position of the rolled product, such as a strip tension distribution.
  • the strip tension distribution can be measured across the width of the rolled product, ie in the axial direction of the work rolls, in front of and/or behind the rolling stand and then used for control in order to keep the position of the rolled product stable.
  • the positioning of the work roll is changed hydraulically, whereby the positioning is realized in a mechanically simple and reliable manner.
  • two hydraulic cylinders are installed that act as actuators.
  • the hydraulic cylinders on the right and left can act directly on the work roll in question, or they can move a structural unit consisting of a work roll and an associated support roll.
  • the position of the work roll can also be varied in other ways, for example by means of one or more electric motors or linear motors.
  • the method set out above in the various embodiment variants can also be used in a rolling mill, in particular a hot rolling mill, with several rolling stands, which together form a rolling train, in particular a tandem train.
  • the rolled product is transported through the roll gap of each of the roll stands along the conveying direction while one or more of the roll stands are opened or closed.
  • a position of the rolled product in front of and/or behind the associated roll gap in the direction transverse to the conveying direction is detected, and the position of the corresponding work roll is changed depending on the detected position so that the rolled product during the opening or closing of the corresponding roll stand is stabilized or held at a target position.
