Definitions

  • the present invention relates to a strip processing device comprising a strip processing cassette for a rolling mill, and a method for removing the strip processing cassette from the strip processing device.
  • drivers metal strip is clamped between a pair of rollers and driven or deflected.
  • Drivers are typically used in rolling trains of rolling mills, for example hot strip rolling mills, where they are arranged upstream of rolled-strip coilers of the coiling stations in order to set the strip tension upstream of the coiler by means of two rolls, namely the driving roller and the supporting driving roller.
  • Directional drivers have the additional object of reducing lateral creeping of the rolled strip prior to coiling.
  • the pivotable driving roller is actuated and positioned against the fixed supporting driving roller in such a way that, as a result of the position of the driving roller with respect to the supporting driving roller, the rolled strip experiences a desired strip tension and a desired lateral displacement.
  • Such directional drivers are known, for example, from EP747147B1 or AT500689B1.
  • EP747147B1 presents a directional driver, the pivotable driving roller of which is arranged mounted between two rockers by means of the two ends of the driving roller axle.
  • the two rockers are connected rigidly to a torsion spring of a frame which forms an axle for the rockers.
  • AT500689B1 discloses a similar directional driver, in which, however, the rockers can be pivoted independently of one another on an axle of a frame.
  • the driving roller and the supporting driving roller of a directional driver have to be cleaned and polished regularly, since, for example as a result of carbon caking, particles of dirt present on the strip to be coiled, or as a result of surface defects in the strip to be coiled which are brought about during the first pass, the surface of the driving roller and of the supporting roller become nonhomogeneous, which can in turn lead to damage to the surface of the strip to be coiled.
  • the driving roller axle is mounted on a bearing region of the rockers, with the driving roller being located in each case underneath the rocker.
  • the bearings of the driving roller are placed in a play-free setting using, for example, spring-activated balancing means.
  • the pair of rockers on which the driving roller is mounted is normally pivoted by means of rocker cylinders into an intermediate position; this is likewise necessary for exchanging the driving roller.
  • the intermediate position is often reached after the pair of rockers has been pivoted through 180°.
  • the driving roller and the supporting driving roller are usually cleaned and sanded or polished by hand in the installed state. Cleaning, sanding and polishing in the plant constitute a safety risk. This is because the persons involved with these processes have to position themselves between the plant components within the plant, which plant components thus have to be reliably shutdown and blocked.
  • drivers are known which overcome the disadvantages of the prior art and which involve a less time-consuming amount of work with fewer safety risks when changing the driving rollers than conventional drivers and methods.
  • Such a driver for a steel strip coiling plant has at least one supporting driving roller mounted on a frame and at least one driving roller which can be adjusted with respect to the supporting driving roller and is mounted on at least one rocker connected to the frame, wherein the driving roller is attached to a bearing region of the rocker, wherein the bearing region is open for the insertion or removal of the driving roller to the side and/or in the upward direction when the rocker is positioned in the operating position, and the driver has a securing mechanism for securing the driving roller at the bearing region.
  • the bearing region is to be understood as the region of the rocker in which the driving roller is attached to the rocker.
  • the bearing region is open for the insertion or removal of the driving roller to the side and/or in the upward direction when the rocker is positioned in the operating position, and therefore the bearing region does not prevent the driving roller from being disinstalled to the side and/or in the upward direction.
  • a driving roller can therefore be removed from the rocker to the side and/or in the upward direction as required without the rocker together with the driving roller having to be removed substantially from the operating position or without the rocker together with the driving roller having to be completely dismantled.
  • Operating position to be understood as a position of the rocker which is assumed during normal operation of the driver.
  • the driver has a securing mechanism for securing the driving roller at the bearing region. This ensures during operation that the driving roller does not undesirably veer off to the side and/or in the upward direction. In the secured state, controlled displacement of the driving roller into different operating positions is possible.
  • the positioning of the driving roller with respect to the supporting driving roller in the secured state can preferably be changed by changing the setting of the securing mechanism to different positions.
  • the securing mechanism comprises a displaceable bar, which can preferably be secured to the rocker.
  • the securing mechanism comprises a swing-action device, the components of which can be swung about at least one axle fastened to the rocker, and which can be secured to the rocker.
  • said swing-action device may involve two arms which can be swung into one another and which are locked by a displaceable wedge. Each of the arms swings about a different axle here.
  • the supporting driving roller is located underneath the driving roller. It is therefore not possible to remove the supporting driving roller in the upward direction while the driving roller is installed in the driver. If the driving roller has been removed, the path for removing the supporting driving roller in the upward direction is open.
  • the distance between the rockers is preferably greater than the length of the supporting driving roller. This ensures that the supporting driving roller can be removed in the upward direction as a result of the free space produced by the removal of the driving roller.
  • the rockers in the operating position is less than the length of the supporting driving roller, it is preferred for at least one of the rockers to be able to be displaced or pivoted in relation to the other rocker when the driving roller has been disinstalled. As a result of this, the supporting driving roller can be removed.
  • the steel strip coiler is preferably a steel strip coiler for a hot strip.
  • the driver is preferably a directional driver.
  • the driving roller and the supporting driving roller are arranged in a holding device.
  • the holding device which may be for example a holding frame, thus contains both the driving roller and the supporting driving roller.
  • the driving roller and supporting driving roller do not have to be removed individually from or inserted individually into the driver, the removal and insertion can be carried out more quickly.
  • the supporting driving roller may be mounted on the frame in a fixed or displaceable manner.
  • the driving roller axle and/or the supporting driving roller axle about which the driving roller or the supporting driving roller rotates comprise/comprises at least two driving roller axle parts and/or supporting driving roller axle parts, wherein at least one of the driving roller axle parts is configured as a shaft stub which is releasably fastened—for example via a connecting flange, a perforated disk having displaceable drive pins, or a claw coupling—to the cylindrical body of the driving roller or supporting driving roller.
  • the shaft stub can be configured here as a hollow shaft, into which a motor-driven shaft can be introduced for driving the driving roller or the supporting driving roller. This makes it possible to remove the driving roller and/or supporting driving roller quickly from the driver, and this reduces a safety risk caused by time pressure when changing the driving rollers.
  • the supporting driving roller can be removed from the driver laterally in the direction of its longitudinal axis. It can also be introduced into the driver laterally in the direction of its longitudinal axis.
  • one end of the rockers can be rotated about an axle while the other end of the rockers is connected to an actuating device such as, for example, a pressure-medium cylinder, preferably a hydraulic cylinder.
  • an actuating device such as, for example, a pressure-medium cylinder, preferably a hydraulic cylinder.
  • the rockers can be pivoted about their axle, for example in order to permit the removal of the driving roller or in order to control or adjust the distance between the driving roller and the supporting driving roller.
  • the bearing region of the driving roller is located between the pivotable end of the rocker and the end of the rocker connected to the actuating device.
  • the rockers can be pivoted about an axle arranged in an axle region of the rockers, and said rockers are connected in an actuating region to an actuating device.
  • the bearing region of the driving roller can, as in EP747147B1 or AT500689B1, be located between the axle region and the actuating region.
  • the axle region can be located between the bearing region and the actuating region.
  • the effective distance of an actuating device which acts on one end of the rocker can also be increased more easily in structural terms in such a construction than in embodiments configured as in EP747147B1 or AT500689B1. As a result of an increased effective distance, the same forces can be achieved with smaller actuating devices or larger forces can be achieved with the same actuating devices.
  • a further part of the internal prior art is a method for removing a driving roller from a driver according to the internal prior art.
  • Opening the securing mechanism is to be understood as meaning that the securement of the driving roller to the bearing region is released.
  • the supporting driving roller in a driver is secured in the driver by securing devices in order to ensure that during normal operation its position does not change at all or its position does not change beyond an acceptable degree.
  • the supporting driving roller can be secured here so that no movement at all is possible. It can also be displaceable to an acceptable or desired degree. The degree of displaceability which is acceptable or desired depends on the respective operating state. In order to be able to change the deflection forces of the driver as a function of the strip thickness and the strip quality, it is possible, for example, to change the distance between the axle of the driving roller and that of the supporting driving roller to a certain degree.
  • An embodiment of the method according to the internal prior art is characterized in that, after removal of the driving roller, it additionally comprises the steps
  • the supporting driving roller can also be removed in the upward direction from the driver.
  • the supporting driving roller can be pulled out of the driver laterally, that is to say in the direction of its longitudinal axis, for the purpose of removal. This can take place before or after the inventive removal of the driving roller. This can also take place during the removal of the driving roller from the driver; in this way, the driving roller and the supporting driving roller can be removed more quickly than if the two removals take place in succession.
  • the method according to the internal prior art then additionally comprises, during the removal of the driving roller, the steps
  • the driving roller and supporting driving roller are removed from the driver in pairs by removing a holding device in which a pair consisting of a driving roller and a supporting driving roller is arranged.
  • the object of the present invention is to permit components of strip processing devices of a rolling mill to be replaced more quickly compared to the prior art by making available a strip processing device and a method for operating the strip processing device.
  • said strip processing device comprises a strip processing cassette mounted on a frame
  • bearing region is open for the insertion or removal of the strip processing cassette to the side and/or in the upward direction from the frame, and the strip processing device has a securing mechanism for securing the strip processing cassette at the bearing region.

  • the strip is processed by interaction between the strip processing cassette and the strip.
  • the remaining parts of the strip processing device serve to support and secure the strip processing cassette.

  • worn devices for processing the strips can be renewed or various types of devices for processing strips can be replaced quickly and easily by removing a strip processing cassette and inserting another strip processing cassette into the frame.
  • the strip processing cassette that is to say one component, has to be removed from the frame or inserted into the frame instead of individual components of the strip processing device contained in the strip processing cassette having to be removed individually from the frame or inserted into it.
