Definitions
- the invention relates to a device for measuring the roll gap between work rolls of a cold or hot rolling stand for rolling out narrow or wide metal strips, in particular non-ferrous metal strips, by means of roll splitters in the form of measuring probes, displacement sensors, electro-hydraulic transducers, magnetostrictive transducers and the like. The like., whose signal can be forwarded as a roll gap setpoint to the servo valves of the pressure oil control for the piston-cylinder units influencing the roll gap.
- the previous design for measuring the nip is carried out using measuring clamps between the work rolls (DE-OS 25 03 130) at stepped diameters next to the roll bales on the drive side and on the operating side of the roll stand.
- the arrangement in the vicinity of the belt edge often causes damage to the device due to belt run or belt breakage.
- the disadvantage of such designs is the high level of maintenance and swiveling the device into the maintenance position hinders the construction of other required products.
- the devices for measuring the roll gap therefore also serve to regulate the inclined position by means of the position or the displacement transducers on the support roll chocks, as a result of which a direct roll gap measurement is given.
- the inclined position of the roll gap cannot be set precisely enough. The reason is that the measurement solution is too far from the roll gap.
- Known devices still work precisely, but are complex and therefore expensive and easy to damage.
- the invention has for its object to provide a roll gap measurement which is also suitable for such cases of the lateral strip run and which is also protected and of low maintenance.
- the position or displacement sensor is provided in at least one bending cylinder for the work rolls for indirect roll gap reference measurement via the positive or negative acting bending cylinders.
- the roll gap measuring device is not only arranged close to the roll gap, but at the same time completely protected within the bending cylinder. This arrangement also leads to little maintenance. Measured value evaluations show that a displacement sensor installation in the bending cylinder represents the roll gap sufficiently precisely for the control against the lateral strip run. A resolution of less than 10 ⁇ m can even be achieved.
- the control of the measured inclined position of the belt is carried out via the adjustment and / or different bending forces in the piston-cylinder units.
- a related task of carrying out the roll gap measurement with a low rolling force is achieved according to an alternative in that the position or displacement sensor is installed at least between the bending blocks or the work roll chocks or between the fixed cylinder block and a movable component for indirect roll gap reference measurement is.
- This solution can be used in cassette construction or in the non-positive work roll bending system in the bending cylinder of the negative or positive acting bending cylinder. It is also advantageous that the roll gap reference values can be used to regulate the position of the bending cylinders.
- the accuracy of the roll gap control can be increased by assigning a position or displacement sensor to each bending cylinder in accordance with the number of bending cylinders in a roll stand.
- a practical embodiment can be designed according to other features in such a way that the position or displacement sensor penetrates a cylinder sleeve, on the end face of which a magnet for the sensor rod of the magnetostrictive transducer is arranged in a central cavity of the piston for the bending cylinder and that Encoder rod, penetrating the piston rod of the bending cylinder in an axial central bore of the piston rod, which ends at a vent hole.
- a position or displacement sensor can be adjusted in a cylinder block for the bending cylinders in a guide tube, which is fixedly arranged in a bending block.
- the guide tube is fixed in one bending block and is slidably guided in the opposite bending block.
- FIG. 1 shows a partial cross section through the work rolls of a hot or cold rolling stand with an axial section through a bending cylinder
- FIG. 2 shows an axial section through the bending cylinder with a position sensor inside
- FIG. 3 shows a section through an alternative embodiment between the Bending blocks or the work roll chocks and
- Fig. 4 is a diagram of the inclined position of the tape to the course of the tape head.
- the work rolls 1 a and 1 b (FIG. 1) are shown partly in section and are each guided by a support roll 2.
- the work roll chocks 3a, 3b are guided in the stands as usual.
- the work rolls 1a and 1b are also held in bending blocks 4a and 4b vertically displaceable to the roll gap 7.
- the bending blocks 4a, 4b are fastened to the roll stand (not shown) of the roll stand.
- the bending cylinders 5a, 5b are arranged in the bending blocks 4a, 4b.
- a position or displacement sensor 6 for the roll gap reference measurement is installed and integrated in the bending cylinder 5a, 5b.
- the position or displacement sensor 6 shown is designed as a magnetostrictive sensor (FIGS. 1 and 2).
- a control system or a control circuit is constructed from the measured values of the position or displacement sensor 6.
- the measured control values result in an exact setting of the roll gap 7 in order to achieve an optimal threading or unthreading into the closed roll gap 7 and for the optimal rolling of metal strips (made of steel or non-ferrous materials) with the desired flatness and the required profile.
- the magnetostrictive position or displacement sensor 6 is shown enlarged in FIG. 2.
- the position or displacement sensor 6 penetrates a cylinder sleeve 8, on the end face 8a of which a magnet 9 for the sensor rod 10 of the magnetostrictive transducer 6a is arranged in a central cavity 11a of the piston 11.
- the piston rod 11b carrying the piston 11b has an axial central bore 12 in which the transmitter rod 10 is arranged.
- the central bore 12 ends at a vent bore 13 with a screw plug 14.
- a guide tube 16 is arranged in a cylinder block 15 near the roll gap 7.
- the guide tube 16 is guided opposite in the bending block 4b by means of a guide bush 17 and the position or displacement sensor 6 is guided or supported by means of a guide rod 18.
- the diagram in FIG. 4 shows the relationship between the inclined position of the roll gap 7 (measured at different points) and the lateral course of the rolled strip (made of steel or softer non-ferrous materials).
- the coefficient of determination R 2 of the linear regression means a favorable value near "1" and is advantageous as a controlled variable. In the lower area, R 2 is smaller than in the upper area and is less suitable as a controlled variable. From these relationships it follows that regulation of the inclined position of the rolled strip by measuring on the bending blocks 4a, 4b can considerably minimize the undesired lateral strip run.
