Definitions

  • the invention relates to a device, a rolling system and a method for regulating a strip tension in the flexible rolling of metal strip.
  • the so-called flexible rolling produces metal strips with different thicknesses that are defined periodically.
  • the length and thickness of the rolled longitudinal thickness profile correspond, for example, to the eventual loading of a sheet metal component.
  • the rolling process is to be designed as cold or hot strip rolling.
  • the strip material to be rolled is unwound from a coil, rolled and then rewound under tension.
  • the corresponding rolling plants can be reversing plants, i. H. after passing through a coil from a first to a second reel device, a next coil can be passed from the second to the first reel device.
  • circuit boards are separated from this strip material, which are used for the production of components with different wall thicknesses.
  • One way to compensate for the speed variation of the metal strip at relatively low rolling speeds is to change the reel speeds.
  • the speed of the reel is regulated depending on the position of the roll gap. If the roll gap opens and a thicker area is rolled, the speed of the reel is increased. If the roll gap is closed and the belt speed is reduced due to the process, the reel speed is also reduced, as in the CN 101890434 A is described.
  • the disadvantage of this method is the limitation of the coil weight and the rolling speed. Due to the inertia, the response time of the system increases with increasing mass. Increasing the mass of the coil leads to a necessary reduction in the rolling speed. On the other hand, an increased rolling speed causes a reduction in the mass of the coil, which increases the system's idle times.
  • DE 103 15 357 A1 discloses a rolling plant for rolling metal strip with a first reel device for uncoiling, from which strip can be unwound with a defined strip starting thickness, a roll stand which comprises at least two work rolls, between which a width-controllable and / or adjustable roll gap is formed and a second reel device for reeling onto which metal strip can be wound with a final strip thickness that is reduced compared to the defined strip starting thickness.
  • the rolling system has first strip storage means with a roller arrangement comprising a plurality of rollers between the first reel device and the rolling stand.
  • the rolling mill also has second strip storage means with a roller arrangement comprising a plurality of rollers between the roll stand and the second reel device.
  • the roles of the first tape storage means and the position of the second tape storage means can be changed relative to each other for tape storage, the metal tape being guided in the form of an "S" with sheets at least partially superimposed.
  • the movement of one of the rollers per belt storage means is adjusted hydraulically, so that the “S” is distorted such that the length of the metal belt is changed between an inlet and an outlet in the respective belt storage means.
  • a device for rolling metal strips with a periodically variable strip thickness in which a compensating or dancer roll is arranged around the strip material, both between a reel for unwinding metal strip and the roll stand and between the roll stand and a reel for reeling metal strip is looped around and the force is controlled at a constant peripheral speed of the rolls of the roll stand which determine the roll gap in order to apply a desired strip tension, the reels being speed-controlled.
  • the dancer rolls are adjusted vertically and linearly in one direction perpendicular to the metal strip.
  • the object of the present invention is to provide a device, a rolling installation and a method for regulating a strip tension in the flexible rolling of metal strip, in which a rapid and precise regulation of the strip tension in the metal strip is made possible.
  • a device for regulating a strip tension in the flexible rolling of metal strip comprising the following: a roller arrangement with at least one dancer roll, the position of which is adjustable for regulating the strip tension of the metal strip, at least one hydraulic drive which is used to adjust the Dancer role is coupled with this, a hydraulic tank for hydraulic fluid, which is connected to the hydraulic drive via a hydraulic feed line, a controllable valve arrangement between the hydraulic tank and the hydraulic drive for controlling the hydraulic drive, a hydraulic pump, with which the hydraulic drive with hydraulic fluid from the Hydraulic tank is supplied, and at least one hydraulic pressure accumulator for intermediate storage from before hydraulic fluid conveyed by the hydraulic pump, the hydraulic pressure accumulator being arranged between the hydraulic pump and the valve arrangement.
  • a quick adjustment of the at least one dancer roll is especially not at high rolling speeds, for example over 25 m / min, and when using large coil masses of, for example, 5 to 25 kg / mm bandwidth with strip widths of 300 to 750 mm, not only by adjusting the To ensure delivery capacity of the hydraulic pump. Therefore, the invention also provides a hydraulic pressure accumulator for temporarily storing hydraulic fluid previously conveyed by the hydraulic pump, the hydraulic accumulator being arranged between the hydraulic pump and the valve arrangement.
  • a high volume of hydraulic fluid for adjusting the at least one dancer roll can be made available from this hydraulic pressure accumulator in the shortest possible time, so that slight fluctuations in the tape tension, if possible below 35%, are achieved.
  • the hydraulic pressure accumulator is to be arranged as close as possible to the hydraulic units for adjusting the dancer roll, so that line losses between the hydraulic pressure accumulator and the adjusting unit for the dancer roll are also kept low.
  • the hydraulic drive can be, for example, one or more hydraulic cylinders per dancer roll.
  • a double-acting hydraulic cylinder or two single-acting hydraulic cylinders can be used to adjust a dancer roll.
  • At least one pressure sensor for determining the hydraulic pressure is arranged in the hydraulic drive.
  • the tape tension of the metal tape can be concluded from the hydraulic pressure.
  • the hydraulic pressure is measured in the hydraulic feed line or in one or more cylinder rooms of the hydraulic cylinder.
  • At least one force sensor for example a tensile load cell
  • at least one force sensor for example a tensile load cell
  • a displacement measuring system for determining the position of the dancer roll can be arranged on the at least one dancer roll. This makes it possible to determine whether the dancer roll is already near an end position of its adjustment path in order to be able to adjust the speed of the metal strip if necessary.
  • the speed of the metal strip can be adjusted by changing the reel speed.
  • the position of the dancer roll tends to be adjusted by changing the speed of the metal band.
  • the hydraulic drive is connected to the hydraulic tank in a fluid-conducting manner via a return line, at least one pulsation damper being arranged in the return line.
  • a high frequency of setting the dancer roll is required, which leads to high flow speeds and possibly cavitation in the hydraulic lines.
  • These pressure fluctuations can be reduced by the at least one pulsation damper in order to avoid damage to the hydraulic system.
  • the at least one pulsation damper is arranged as close as possible to the hydraulic cylinder.
  • a compensation tank can be arranged downstream of the at least one pulsation damper in order to allow further expansion of the hydraulic fluid as close as possible to the hydraulic drive.
  • the passage of the hydraulic fluid, starting from the expansion tank to the hydraulic tank, can then be based purely on gravity, which counteracts further cavitation.
  • a check valve can be arranged between the compensation tank and the hydraulic tank.
  • the dancer roll is arranged to be horizontally adjustable. In principle, however, an adjustment direction of the dancer roll that deviates from the horizontal direction is also conceivable.
  • the roller arrangement can have at least one further roller in addition to the at least one dancer roller, the at least one dancer roller and the at least one further roller being arranged vertically one above the other in such a way that the metal strip is guided in the form of an S or as an S-shaped loop ,
  • a rolling system for flexible rolling of metal strip comprising the following: a rolling stand with two work rolls, between which a width-adjustable roll gap is formed, a first strip guide unit with a first reel for unwinding metal strip, one second strip guide unit with a second reel for reeling rolled metal strip.
  • a device according to the above-described embodiments is arranged between the respective reel and the roll stand.
  • a further solution to the problem consists in a method for regulating a strip tension in the flexible rolling of metal strip in a rolling installation with a device as described above, the valve arrangement being controlled as a function of the strip tension of the metal strip and the hydraulic drive at least partially providing hydraulic fluid at short notice is fed with hydraulic fluid previously stored in the at least one hydraulic pressure accumulator.
  • the hydraulic pressure in the hydraulic drive can be measured, the hydraulic pressure being used to infer the strip tension in the metal strip and the valve arrangement being controlled as a function of the strip tension determined.
  • the forces acting on a roll of the roller arrangement from the metal strip can be measured, the forces being ascertained as to the strip tension in the metal strip and the valve arrangement being controlled as a function of the determined strip tension.
  • the position of the dancer roll of the at least one strip guide unit can be determined via a path measuring system, the speed or speed of the reel of the at least one strip guide unit being controlled depending on the position of the dancer roll. This can be used to change the position of the dancer role.
  • the speed of the dancer roll can be reached shortly before reaching a defined first end position, in which the metal band length between an inlet into the roller arrangement and an outlet from the roller arrangement first reel to be increased.
  • a defined second end position of the dancer roll in which the metal strip length between the entry into the roll arrangement and the exit from the roll arrangement takes on a greatest value, the speed of the first reel can be reduced. This prevents the dancer roll from having to be adjusted beyond the two end positions and kept in a central area if possible.
  • the roll gap setting of the roll stand is determined, the valve arrangement being controlled in addition to the strip tension of the metal strip as a function of the roll gap. This enables a feedforward control as a function of the roll gap setting, which in particular in combination with the control from the determination of the strip tension ensures a short reaction time of the system.
