Definitions

  • the invention relates to a method for presetting cold-forming installations, such as cold rolling mills, temper rolling mills, stretch bending mills, straightening machines and other.
  • Cold rolling mills are used in reversing and tandem construction due to a preprocessing plan pre-set before the start of rolling. This should be the Deformations caused by the predicted stresses Rolling stands compensated and a rolled product with the desired dimensions getting produced.
  • strain hardening is known, for example, from EP-A-0 102 937 (US Pat used there for pitch control) of EP - A - 0 436 762 and JP - A - 60 250 816 known, wherein in the latter the measurement of the hardness of Walzgutes is mentioned before the work hardening.
  • the invention is based on the object, a method for optimal Stichplanaustechnisch to create for the respective Walzcharge.
  • the stated object is achieved in that the hardness of the deformed Material measured just before its cold deformation and to correct its hardening curve and the preset for stitch plan optimization based on it the cold deformation plant is used.
  • the advantage of adapting the hardening curve about a hardness measurement is that on the one hand deviations in the Umformfesttechnik of a material (depending among other things on the chemical composition, differences in cooling after hot rolling or during the annealing process, structural state in general) without prior information directly before the start of rolling can be included in the layout design and on the other, different materials with similar hardening behavior can be managed with only one hardening curve.
  • the standard solidification curve of a material or a Material group with associated standard values of hardness, yield strength, Tensile strength, etc. by additive or multiplicative linkage with a Correction member is corrected, the at least one of the measured hardness value contains determined tensile strength.
  • An advantageous development of the invention is that the difference between the calculated by means of hardness measurement and the effective measured during rolling rolling force of the first stand or the first stitch for mathematical correction of the predicted rolling force of the following rolling stand in tandem systems or the following trick is used in reversing. Since a further adaptation of the solidification curve by hardness measurement between the rolling stands of a tandem mill is not possible, a mathematically determined correction value for the rolling force of the respective following rolling stand is determined from the difference between predicted and measured rolling force of a rolling stand.
  • Reversing stands require a hardness measurement before each stitch possible but costly and time consuming. However, it is sufficient, the hardness only in the inlet from the first stitch to Measure and deviations of the derived rolling force as Correction value to be considered in the second stitch. Should the measured rolling force is still too large deviations From the precalculated exhibit is another Hardness measurement before the third stitch makes sense.
  • the hardness measurement is dynamic and preferably at several Make the material to be deformed is the required measuring time minimized and the measurement result averaged and therefore representative of the respective batch.
  • the known EQUOTIP measuring method is used used.
  • the hardness measurement is preferred during process-related downtimes of Cold deformation systems takes place. This does not occur Delay in the production process. So can the hardness measurement in tandem roads preferably between uncoiler and Welding machine done during welding and thus the Take advantage of welding time. Accordingly, the hardness is measured in Reversier Nos.
  • each k f ( ⁇ ) value is multiplied by the factor k (H 0 , H 1 , R m0 ).
  • the inventive method is not only suitable for Cold rolling mills but also for all types of Molding scaffolding, stretch bender, straightening machines (band and Sheet metal), as well as for cold profile straightening machines and Cold rolling mills for profiles and wire.
