Definitions

  • the invention relates to a method for measuring the rolling forces acting on rolling mill rolls during rolling.
  • the roller bearing force is usually used today to determine the rolling force.
  • the measuring locations are relatively far from the location of the introduction of the rolling force, and the rolling stands have, due to their design, play and backlash, which result in falsifications and time delays in the measured width.
  • the hysteresis phenomena that occur are particularly disadvantageous.
  • the invention is therefore based on the object to determine the load on the roll promptly and close to the point of application of force in a simple manner from the roll and to make it accessible for the control of the rolling processes.
  • roller itself is used to determine the rolling force acting on it. It is crucial when using the roller as a measuring location that the stress per measuring location is measured in more than one angular position, based on the roller axis. This is done by installing at least two sensors per measuring point at different angles to one another.
  • the rolling mill rolls are designed so that they do not require surface cooling, are resistant to thermal shock and have a long service life.
  • the rolling mill rolls are made of an alloy with an average content of 0.05% C 0.50% Si 1.80% Mn 15.00% Cr 1.35% Mo 25.00% Ni 0.20% V 2.10% Ti 0.005% B Rest impurities consist.
  • strain gauges or semiconductor strain gauges can be used as measuring transducers, which transform the material expansion or deflection of the roller into changes in resistance. 1 to 3, they are either attached directly to the inner wall 4 of a central measuring bore 1 or of a plurality of measuring bores 2, or else arranged on pre-wired measuring bodies 5 into the measuring bore 1 of the roller body 3.
  • Measuring methods are also known which measure deflections optically.
  • the deflection of a light beam emitted by a light source 6 from the zero position of the roller axis caused by the bending of the roller is measured with an optical receiver 7.
  • the receiver 7 can consist of a single cell, of two single cells offset by 90 degrees or of a flat reception screen.
  • glass fibers are introduced parallel to the roller axis in eccentrically arranged measuring bores and the change in length resulting from the bending of the roller in two opposite glass fibers is measured as interference.
  • the control of the sensor system rotating with the roller and the transmission of the information out of the roller becomes touching, for example via slip rings, or implemented without contact, for example electromagnetically or optically.
  • the courses and dependencies of the measuring signal shown in FIG. 5 result in principle.
  • an element of the roller is alternately compressed and stretched during rotation.
  • the frequency of the signal change is proportional to the speed of the roller, the amplitude of the measurement signal depends on the relative position of the element concerned to the direction of force application and on the amount of force applied.
  • Fig. 6 the relationships are shown with two sensors offset by an angle of 90 degrees. It is typical of the 90 degree arrangement that while one measuring point is showing the measured value zero, the second measuring point has the maximum amount.
  • Fig. 7 is used to explain the relationships and some sizes used.
  • the two measuring devices x and y are at an angle of 90 degrees to each other.
  • the current relative position to the vertical is given by the angle Phi.
  • the normal force F N to be determined is composed of the vectorial addition of F Nx and F Ny .
  • the angle of the force introduced, based on the stationary vertical, is thus known at all times.
  • the force F N is in principle a rectified signal, which reflects the absolute amount of the stress due to the absolute height (amount of F N ) and reflects the position in relation to the vertical by the angle gamma.
  • the force F N can be split into its horizontal and vertical components by vectorial force decomposition.
  • the vertical force F S corresponds to the bearing force measured in the vertical direction with a good rolling force measurement.
  • the horizontal force F H depends on the deformation conditions and the friction conditions in the roll gap. In addition, components from tensile forces that are transmitted via the rolling stock can be contained in the horizontal force.
  • the rolling stock can be located in two or more roll stands at the same time, as is shown in FIG. 10.
  • the knowledge of tensile forces that are transmitted between two rolling stands via the rolling stock is of great importance. If the tractive force is known, the tractive force can be regulated to a desired, predetermined level by influencing the stand speeds and stand settings.
  • F H the measured horizontal component of the rolling force
  • F HO horizontal component of the rolling force in draft-free operation
  • F HR Retraction that is exerted on the rolling stock against the rolling direction by the existing roll stand
  • F HV preference that is exerted on the rolling stock via a rolling stand with a larger number n - index for the framework no. (used only when needed)
  • the measurements are carried out on rolling mill rolls which do not require surface cooling, are resistant to thermal shock and have a long service life.
  • Cooling water is currently applied to the surface of the rolls in most deformation steps. This cooling does not allow the heating of the roller during the because of the great inaccuracy To use the rolling process as a measurement variable for determining the deformation work in addition to the rolling force.
  • a stable austenite is used as the material, which according to the steel-iron list bears the brand name X5 NiCrTi 25 15 with the material no. 1.4980 or 1.4944 for aviation and the international trade name A 286.
  • the use according to the invention as a heat-resistant material for the production of rolling mill rolls has the advantage that - surface cooling is not required, - due to its thermal shock resistance, the formation of surface cracks during the rolling process is avoided, -
  • the service life in operating hours or in tons per roll lot is so long that frequent changeovers are not necessary, both from the point of view of the operating time and from the point of view of the financial expenditure, -
  • the thermal conductivity is better than with conventional rolling materials.
  • the very complex use of a full roller at shallow depths can be replaced by using a jacket made of the aforementioned material and shrunk onto an axle made of high-strength steel.
