Method for automatically calibrating vertical rollers of a vertical roller frame and calibration arrangement for carrying out said method

Abstract

A method for the automatic calibration of vertical rolls of a vertical rolling stand, each of which is supported in a vertical roll unit which is adjustable with respect to a predetermined center line of a plurality of components arranged in a rolling train, including the steps of a) moving the vertical roll units into a calibration position transverse to the center line against at least one stationary stop of the vertical rolling stand, which has a certain known position with respect to the center line , b) calculating a calibrated initial distance Akal between an outer edge of a vertical roll facing a rolled stock or the center line and the center line in the calibration position, and c) adjusting the vertical roll units to a defined operating position.
