Method and device for determining the tension or the tensile stress in a metal strip

摘要

Method and device for determining the tension or the tensile stress in a metal strip between two roll stands, between a roll stand and a coiler, in a breakdown stand or in front of or behind a deflection roll, the excursion of the metal strip being measured, and the natural frequency of the metal strip being determined on the basis of the excursion of the metal strip.
