Abstract

Ein Universalwalzgerüst mit Horizontalwalzen (1, 2) und Vertikalwalzen (3, 4) wird wie folgt kalibriert:

  • Die Vertikaleinbaustücke (7, 8) derart zwischen die Horizontaleinbaustücke (5, 6) gefahren, daß zwischen den Horizontalwalzen (1, 2) und den Vertikalwalzen (3, 4) Vertikalwalzspalte (v1, v2) verbleiben, und zwischen den Vertikaleinbaustücken (7, 8) einerseits und den oberen und/oder unteren Horizontaleinbaustücken (5, 6) andererseits Distanzstücke (16) angeordnet.
  • Die Horizontaleinbaustücke (5, 6) werden maximal mit einer Verfahrkraft (FV) zugefahren, bis sie an den Vertikaleinbaustücken (7, 8) bzw. den Distanzstücken (16) anliegen. Danach werden sie mit einer Kalibrierungskraft (FK) beaufschlagt, die größer als die Verfahrkraft (FV) ist.
  • Sodann werden angefahrene Positionswerte (p) der Horizontaleinbaustücke (5, 6) erfaßt und aus den Positionswerten (p) Referenzpositionen für nachfolgende Walzvorgänge ermittelt.

A universal roll stand with horizontal rolls (1, 2) and vertical rolls (3, 4) is calibrated as follows:
  • The vertical chocks (7, 8) are moved between the horizontal chocks (5, 6) such that vertical roll gaps (v1, v2) remain between the horizontal rolls (1, 2) and the vertical rolls (3, 4) and between the vertical chocks (7, 8). 8) on the one hand and the upper and / or lower horizontal chocks (5, 6) on the other hand spacers (16) are arranged.
  • The horizontal chocks (5, 6) are closed with a maximum of one traversing force (FV) until they abut the vertical chocks (7, 8) or the spacers (16). Then they are subjected to a calibration force (FK) that is greater than the traversing force (FV).
  • Then approached position values (p) of the horizontal chocks (5, 6) are detected and reference positions for subsequent rolling operations are determined from the position values (p).
