Definitions
- the invention relates to a device and a method 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.
- the object of the invention is to develop a known device and a known method for guiding a metal strip in such a way that they have an alternative device and an alternative method for measuring the force acting on the roller.
- the solution consists in that the measuring device comprises: a sensor device for detecting the deformation of the bearing block for the roller when guiding the tape and an evaluation device for calculating the force acting on the roller from the detected deformation of the bearing block by the sensor device.
- the term "band” in the sense of the invention is fundamentally very broad: in general, it means bands of any material and of any desired cross-section, including ropes or threads, but in particular the term means metal bands, especially slabs.
- roller is likewise to be understood very broadly, and these wheels may in principle also be wheels or deflecting rollers.
- roller is used here in the sense of a strand guiding roller in a strand guiding device to understand a roll of a rolling stand or in the sense of a role of a looser or intermediate storage for metal strip.
- the claimed indirect method for measuring the roller force has the advantage that it can be installed with relatively little effort and reliably and reliably delivers 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.
- bearing block or the carrier device has a cavity or a recess for receiving the sensor device and / or the evaluation device, this has the advantage that these devices are then arranged in a space close to the location of the deformation to be measured and that they are in the Cavity or the recess from environmental influences, especially moisture, can be protected.
- 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.
- Particularly simple is the design of the vulnerability in the form of a slot.
- 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 a device for guiding a metal strip
- FIG. 2 shows a bearing block of the device in the unloaded state
- FIG. 3A shows a bearing block in the unloaded state
- FIG. 1 shows the device 100 according to the invention merely 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. In the strand guide device shown in Figure 1, two rollers 130 are arranged opposite one another; Together they form a roller gap in which the metal strip 200 is guided.
- Figure 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 one
- FIG. 2 also shows a measuring device 140 which comprises a sensor device 142 and an associated evaluation device 144.
- the sensor device 142 is used to detect the deformation of the bearing block under load, d. H. when the strip 200 is being guided.
- 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 the loaded state, FIG. 3B.
- FIG. 3B clearly shows the deformations resulting from the load F, in particular compression of the bearing block.
- the measuring device 142 is designed for the embodiment shown in Figures 2 and 3 in the form of a distance sensor, which preferably continuously detects a narrowing of the slot 124 under load compared to a larger slot height in the unloaded state.
- 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.
- Figure 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 can be measured without difficulty and thus enable a sufficiently large measuring 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. On the other hand, however, it must also be ensured that the bearing block 120 is not unduly weakened by the weak point. Rather, z. B. in an embodiment of the device as a strand guiding device to ensure that the deformation of the weak point remains so small that the strand shell of a slab is not overloaded by the change of the roll position under load.
