Definitions

  • the invention relates to a device for guiding a strip, in particular a metal strip by means of one or more rollers. It is the while guiding the tape, d. H. Measured under load on the rollers acting roller force.
  • rollers of a strand guiding device are made by means of hydraulic cylinders.
  • each roller is associated with one load cell or load cell each.
  • the load cell is between the bearing block in which the roller is mounted and a segment traverse installed.
  • the present invention seeks to develop a known device for guiding a metal strip to the effect that the sensor device and / or the evaluation device on the one hand arranged close to the location of the deformation to be measured and on the other hand protected from environmental influences.
  • the solution consists in that the bearing block whose deformation is measured has a cavity or a recess for receiving the sensor device and / or the evaluation device.
  • the cavity in the bearing block offers the advantage that the sensor device and / or the evaluation device, if installed there, are arranged spatially close to the location of the deformation of the bearing block to be measured and, moreover, in the bearing block from environmental influences , especially from moisture, are protected.
  • band in the context of the invention is basically very broad. So he basically means bands of any material and with any cross-sections, including ropes or threads. In particular, however, the term means metal bands, especially slabs.
  • wheels are also to be understood in the context of the invention also very broad. So these wheels can basically also be wheels or pulleys.
  • roll is to be understood here in the sense of a strand guide roll in a strand guiding device, in the sense of a roll of a rolling stand or in the sense of a roll of a looper or intermediate store for metal strip.
  • the claimed indirect method for measuring the roller force has the advantage that it can be installed with very little effort and also reliable and reliable measurement results for the roller forces over a longer period of time.
  • An embodiment of the sensor device in the form of an ultrasonic sensor, an eddy current sensor or an optical distance sensor advantageously offers the possibility of a non-contact measurement of the deformation, in which only a small amount of design measures are required on the bearing block.
  • the bearing block has a suitable weak point, if its deformation when guiding the strip from the sensor device is representative of the deformation of the bearing block is easily detectable.
  • the sensor device can then advantageously be designed as a simple and inexpensive distance sensor, which then detects the deformation of the bearing block under load in the form of a narrowing of the slot.
  • FIG. 1 shows the device 100 of the invention only by way of example in the form of a strand guiding device. It serves to guide a band here 200 in the form of a metal strip, in particular in the form of a slab.
  • the carrier device 110 of this device 100 is designed in the form of a segment frame. On the segment frame or on its truss bearing blocks 120 are attached to receive rollers 130.
  • strand guide means are two rollers 130 arranged opposite one another; Together they form a roller gap in which the metal strip 200 is guided.
  • FIG. 2 shows a cross section through a bearing block 120.
  • the bearing block 120 is fastened to the carrier device 110 with screw connections 128.
  • the bearing block 120 has an artificial weak point 124 in the form of a slot.
  • a measuring device 140 can be recognized, which comprises a sensor device 142 and an associated evaluation device 144.
  • the sensor device 142 is used for detecting the deformation of the bearing block under load, ie when guiding the belt 200.
  • the evaluation device 144 is used to calculate the desired roller force acting on the roller 130 in the event of load from the deformation of the bearing block detected by the sensor device 142.
  • FIGS. 3A and 3B show a comparison between the bearing block in the unloaded state, FIG. 3A , and in a loaded condition, FIG. 3B.
  • FIG. 3B allows the deformation resulting from the load F, in particular compression of the bearing block, to be clearly recognized.
  • the measuring device 142 is for in the Figures 2 and 3 embodiment shown in the form of a distance sensor, which preferably detects a constriction of the slot 124 under load compared to a larger slot height in the unloaded state, preferably continuously.
  • the detected restriction of the slot 124 represents the deformation of the bearing block 120 under load.
  • the mathematical relationship between the distance measurement signal of the distance sensor and the forces acting on the roller is determined by the characteristic of the measuring sensor and the exact geometry of the bearing block. It creates a simple linear or nearly linear relationship with polynomial portions, so that the acting Forces can be calculated in a simple way from the measured deformations.
  • the evaluation device 144 calculates the desired force F acting on the roller 130 in the event of load.
  • FIG. 3B shows an example of the bearing block deformed under load, but heavily oversubscribed.
  • the deformation of the bearing block in the region of the weak point or the slot in a strand guiding device at maximum permissible roller load is only 0.02-0.3 mm.
  • Geometric changes on this scale are easily measurable and thus allow a sufficiently large measurement signal as a representative of the deformation of the bearing block.
  • the weak point offers a suitable means of transforming the deformation of the bearing block into a measurable order of magnitude or making it visible.
  • the weakness is on the one hand to train accordingly.
  • it must also be ensured that the bearing block 120 is not unduly weakened by the weak point. Rather, z.
