Definitions

  • the invention relates to a device for measuring a roll gap between work rolls of a cold or hot rolling stand for the rolling of narrow or wide metal strips, in particular of non-ferrous metal strips, by means of at least one position or displacement sensor for indirect roll gap reference measurement.
  • the means for measuring the roll gap are therefore also used to control the skew about the employment or the transducer on the support roller chocks, whereby a direct roll gap measurement is given.
  • the skew of the nip is not precise enough adjustable. The reason is that the measurement is too far away from the roll gap.
  • the invention has for its object to provide a suitable even for such cases of the lateral band path roll gap measurement at low rolling force, which is also designed to be protected and low maintenance.
  • the position or displacement transducer is between the lead blocks or work roll chocks or between the stationary cylinder block and a movable nip reference measurement member installed and it is a regulation of the measured at the bending blocks inclined position of the rolled strip provided via a position of the roll gap influencing piston-cylinder units and / or setting a different bending forces in the, the roll gap influencing piston-cylinder units.
  • a practical embodiment may be designed according to other features in that the position or Weggeber penetrates a cylinder liner, at the front side of a magnet for the encoder rod of the magnetostrictive transducer is arranged in a central cavity of the piston for the bending cylinder and that the encoder rod, the piston rod penetrates the bending cylinder penetrating in an axial central bore of the piston rod, which ends at a vent hole.
  • a position or displacement sensor is adjustable, which is fixedly arranged in a bending block is.
  • the guide tube is fixedly arranged in a bending block and slidably guided in the opposite bending block.
  • another embodiment is provided such that the guide tube is slidably mounted in a guide bush in an opposite bending block.
  • the work rolls 1a and 1b ( Fig. 1 ) are shown partially cut and are guided by a respective support roller 2.
  • the work roll chocks 3a, 3b are guided in the uprights as usual.
  • the work rolls 1a and 1b are also held in bending blocks 4a and 4b vertically displaceable to the nip 7.
  • the bending blocks 4a, 4b are attached to the (not shown) roll stand of the rolling stand.
  • the bending cylinders 5a, 5b are arranged.
  • a position or displacement sensor 6 is installed for the roll gap reference measurement and integrated into the bending cylinder 5a, 5b.
  • the drawn position or displacement sensor 6 is designed as a magnetostrictive encoder ( Fig. 1 and 2 ). From the measured values of the position or displacement sensor 6, a control system or a control loop is constructed.
  • the measured control values bring about an exact adjustment of the roll gap 7, in order to achieve optimum threading or unthreading into the closed roll gap 7 and for optimum rolling of metal strips (made of steel or non-ferrous materials) with desired flatness and the required profile.
  • the magnetostrictive position or displacement sensor 6 is in Fig. 2 shown enlarged.
  • the position or displacement sensor 6 penetrates a cylinder bushing 8, on the end face 8a of which a magnet 9 for the encoder rod 10 of the magnetostrictive transducer 6a is arranged in a centric cavity 11a of the piston 11.
  • the piston 11 carrying the piston 11b has an axial central bore 12, in which the encoder rod 10 is arranged.
  • the central bore 12 terminates at a vent hole 13 with a locking screw 14.
  • Fig. 3 is in each case a cylinder block 15, a guide tube 16 is arranged near the nip 7.
  • the guide tube 16 guided in the bending block 4b opposite by means of a guide bush 17 and the position or displacement sensor 6 is guided or mounted by means of a guide rod 18.
  • FIG. 4 In the diagram of Fig. 4 the relationship between the slant of the roll gap 7 (measured at different locations) and the lateral running of the rolled strip (made of steel or softer non-ferrous materials) is shown.
  • the coefficient of determination R 2 of the linear regression means close to "1" a favorable value and is advantageous as a controlled variable. In the lower region, R 2 is smaller than in the upper region and is less suitable as a controlled variable. From these contexts follows that a regulation of the inclination of the rolled strip by measuring at the bending blocks 4a, 4b can significantly minimize the unwanted lateral band course.
