摘要:
The invention relates to a method for determining the rolling or guiding gap of the roll stands or guide stands in a multi-stand rolling mill, wherein a comparison scale is positioned at at least one stand, preferably at the first and the last stand, and subsequently the rolling or guiding gap of the respective stand is determined. In said method, a camera is arranged at one of the input or output sides and a transmitter for reference means, a reference transducer and/or a reference scale is arranged at the other of the input or output sides before the comparison scale is positioned, such that adjustment operations at the camera can subsequently be avoided.
