Abstract

Gemäß der Erfindung werden thermische und mechanische Form- oder Volumenveränderungen in einer Walzmaschine (1) korrigiert, indem die relative Lage der Walzen (2,3) oder Werkzeuge zueinander während der Umformung bestimmt wird und nach der Umformung auf eine Soll-Relativlage korrigiert wird, wenn unzulässige Abweichungen von der Soll-Relativlage auftreten.According to the invention, thermal and mechanical shape or volume changes in a rolling machine (1) corrected by the relative Position of the rollers (2,3) or tools determined each other during the forming is corrected and after the deformation to a desired relative position is when impermissible deviations from the desired relative position occur.

In der Umformphase werden die Walzenachsen (A,B) abhängig von der Drehposition gesteuert.
