Definitions

  • the method described in DE 197 20 768 C1 aims to provide a basis for the determination to create, by the mouth width with simple metrological and mathematical means exactly over the entire strand guidance is adjustable, and beyond that, the current position of the sump tip within the slab.
  • the method is based in Kem on a dynamic measurement by excitation of the strand in oscillation, with the help of which it is recognizable whether at a measuring point a trend to larger or smaller mouth width, away from the optimal jaw width occurs, in order then the detected deviation with targeted Correct action.
  • the force relative to the jaw width results in a hysteresis curve. This has a relatively small area when the shell is still thin and the swamp is relatively large.
  • the hysteresis curve has a relatively large area as the shell continues to grow and sump volume decreases, and assumes a particularly slender shape when the strand is solidified.
  • the mouth width is changed by an oscillation about a predeterminable center line of the desired slab thickness.
  • force-displacement characteristics are evaluated, for which, among other things, the slope of the characteristic curves in the force-displacement plane and their intersection are taken into account for the required evaluation.
  • the selected oscillation quantity should be selected so that the dynamic influences on the still relatively thin strand shell after leaving the mold are kept negligibly small
  • the amplitude of the oscillating mouth width should be set to a value that prevents a plastic deformation of the strand shell, this information is given by the expert no clear, understandable teaching on technical action based.
  • the invention has the object to improve the known method in the way and to design, in its metrological implementation with obtaining optimal measurement results with certainty the disadvantages and difficulties due to detrimental deformation of the strand shell or interference to avoid their structure such as cracking.
  • a method referred to in the preamble of claim 1 with the invention that is determined from a variety of force-displacement measurements along the
  • An embodiment of the method further provides that from a change in the area of a hysteresis curve -. B. decrease in area - the position of the sump tip can be determined. And finally, it is advantageously possible that from a change in the area of a hysteresis curve -. B. when the area decreases - an increase in strand consistency is determined.
  • a force-displacement diagram of the gap adjustment This is composed of a large number of small force-displacement curves, which were each determined individually by means of an oscillation with a low amplitude. From this, a reliable as well as rapid determination and adjustment of the optimal jaw width is recognizable and possible for the practical casting operation. It can already be seen after an oscillation with the smallest amplitude whether the jaw width is too large or too small and has to be corrected.
  • the individual curves - each one hysteresis - engage each other like links in a chain and show along the line the course of the force over the jaw width.
  • the invention so to speak, is an "X-ray image" of the strand and optimally solves the problem set in the beginning.
