Definitions

  • the invention relates to a device for rolling Metal strips, in particular steel strips, with a Roll stand, with a winding device and with at least one between the roll stand and the winding device arranged strip tension compensation device.
  • the invention also relates to a method for rolling Metal strips, especially for cold rolling Steel strips in which the strip to be rolled is coiled uncoiled, rolled in a roll stand and then is coiled, the one resting on the metal belt Belt tension regulated by means of a belt tension compensation device becomes.
  • the object of the invention was based on the a device and to create a process with which to deal with their geometry high quality metal strips with reduced Manufacturing control and device engineering effort to let.
  • the invention is based on the knowledge that is also effective through a horizontal direction Adjustment of a deflection roller from the one rolled Belt between roll stand and winding device traveled distance can be adjusted so that the Speed fluctuations are minimized and, provided they do occur within short response times can be compensated.
  • the number of Redirections that the tape on its way between Must pass through the winding device and roll stand also reduced to a minimum. So are at inventive procedure and configuration between the roll stand and the respective winding device in the Usually, a maximum of two redirections are sufficient to achieve the Make speed compensation according to the invention and ensure the smooth running of the rolled strip to be able to.
  • the adjustability of the pulley Belt tension compensation device in that the position of the Roller is linearly adjustable in the horizontal direction.
  • the role can, for example, from one a rail movable carriage carried be based on a suitable actuator easy to move.
  • Such a car will by means of the respective drive from a position in which a first distance between the roll and the roll stand exists, moved into at least a second position in which another distance between the roll and the roll stand consists.
  • the strip between the roll stand and the pulley of the belt tension compensation device in one single horizontal plane can be performed. To this In this way, optimal conditions can also be found in the roll gap then ensure if a "flexible rolling" with strong fluctuating loads on the strip and the roll stand is carried out.
  • the pulley despite the adjustment required pivotal movement to allow that Belt between the roll stand and the deflection roller essentially the swing arm can be guided horizontally for example, be coupled to an actuating device, over which their length can be changed during operation.
  • the deviations by which the strip run between the nip and deflection roller from the horizontal plane of the roll gap deviations can also be minimized by the fact that the Swing arm in a middle position of her in the company executed pivoting movements substantially perpendicular is aligned.
  • the actuating forces should be minimized the middle position of the rocker can also be chosen in this way that in this middle position they are one against the Horizontal inclined position.
  • the invention can be particularly effective Use the device if with it metal strips changing strip thicknesses generated by flexible rolling should be.
  • the rolling stand in itself known manner equipped with an actuator be the height of the roll gap during operation changed so that the rolled strip in one position a small strip thickness and in another position receives larger strip thickness.
  • FIG. 1 The one shown in FIG. 1 that can be operated in reverse operation Device 1 for cold rolling a steel strip S is with an unwinder 2, a first Strip tension compensation device 3, a roll stand 4, one second band tension compensation device 5 and one Rewinder 6 equipped.
  • the Unwinder 2, the first Belt tension compensation device 3, the roll stand 4, the second band tension compensation device 5 and Rewinder 6 are placed in line and are from the cold-rolled steel strip S in the conveying direction F happened in succession.
  • the band tension compensation devices 3.5 each comprise a car 7.8.
  • Each of the carriages 7,8 can be set up independently rails 7a, 8a arranged in a horizontal plane by means of each of a suitable drive linear between the Roll stand 4 and the unwinder 2 and the Roll stand 4 and the winding device 6 move become.
  • the carriages 7,8 each carry a role 9,10, the Axis of rotation essentially parallel to the axis of rotation the work rolls of the roll stand 4 is aligned.
  • the position of the axis of rotation of the roller 3 is oriented taking into account their diameter, that the steel strip S between the roll 3 and the roll gap 4a of the roll stand 4 in a constant through which Rolling gap 4a running horizontal plane H runs.
  • Steel strip S is on the roll 10 of the second Belt tension compensation device 5 deflected lying thereon, that it is from below into the take-up device 6 wound coil CB runs in.
  • the position of the Axis of rotation of the roller 10 of the second Belt tension compensation device 5 is aligned so that the steel strip S between the roll stand 4 and the Roll 10 runs in the horizontal plane H.
  • Both role 9 and role 10 are from Steel belt S wrapped around less than 90 ° of its circumference.
  • the band tension compensation device 3 in the direction of Roll stand 4 moves.
  • the Strip tension compensation device 3 goes to the roll stand 4 a shortening of the distance between the Coil CA and the roll stand free running tape length.
  • the position in question the band tension compensation device 3 is in FIG. 1 shown in dashed lines.
  • the device 20 shown in FIG. 2 corresponds in terms of their functional units and the way they work the band tension compensation devices 3.5 of the previous Device 1 explained.
  • a deflection roller 11 arranged in the device 20 between the Unwinding device 2 and the associated Belt tension compensation device 3 .
  • the deflection roller 11 is so on the one hand positions that the steel strip S at maximum diameter of the coil CA essentially runs horizontally from below to the pulley 11 and then is deflected upwards at her so that it is on the Coil CA side facing the roll 9 of the Bandzugaustechnischs owned 3, where it then hits again in the horizontal plane H in the direction of Roll gap 4a of the roll stand 4 is deflected.
  • Through the Deflection roller 11 is thus ensured that the steel strip S even with large diameters of the coil CA in enters the conveyor path of the device 20.
  • the device 20 is between the band tension compensation device 5 and the Winding device 6 a deflection roller 12 is provided. Also this deflection roller 12 is positioned so that the Steel strip wound on the Coil CB with maximum circumference of the coil CB is guided essentially horizontally.
  • steel strip S is first on roll 10 the band tension compensation device 5 deflected such that it on the side assigned to the roll stand 4 on the Deflection roller 12 hits. The steel strip S is then attached to it again directed towards the coil CB.
  • the device 30 shown in FIG. 3 also corresponds in its basic concept that shown in Fig. 1 Device 1. It is accordingly also with a Winding device 2, a first Belt tension compensation device 33, a roll stand 4, one second band tension compensation device 35 and one Rewinder 6 equipped in the conveying direction F in line from the cold to be rolled Steel belt S are run through.
  • the strip tension compensation devices 33,35 each formed by a rocker 36 and 37, respectively one end each parallel to the axis Rotation axes of the roll stand aligned pivot axis 38.39 are pivotally mounted.
  • the swivel actuation takes place thereby by hydraulic cylinder 40.41.
  • other drive types can also be used for this purpose use that have a comparably fast response time and ensure a sufficiently high generation of force.
  • each rocker 36, 37 carries one Roll 9.10.
  • the length of the wings 36.37 is below Taking into account the diameter of each of them worn roll 9.10 dimensioned so that with vertical Alignment of the wings 36,37 the steel strip S between the rollers 9, 10 and the roll gap 4a of the roll stand 4 in the horizontal plane H running through the roll gap 4a is led.
  • the vertical position corresponds the respective middle position around which the wings 36, 37 be pivoted during the rolling operation.
  • the rocker 37 is in the direction the winding device 6 moves when in the outlet area 4c of the roll stand 4 there is too little strip tension.
  • the distance between the roller 10 carried by the rocker 37 and the roll stand and in turn the associated between the Coil CB and the mill stand 4 increased free running length of strip, so that after a sufficiently wide swiveling also in Infeed area 4c of the roll stand 4 the required Belt tension is restored.
