A method of measuring the tensile stress distribution in a metal strip between two roll stands, between a roll stand and a coiler, within a blooming stand, or upstream or downstream from a deflection roller, with the metal strip being deflected and the deflection of the metal strip being measured by two or more sensors arranged across the width of the metal strip. The tensile stress distribution in the metal strip is calculated as a function of the deflection of the metal strip. A correction is performed on the measured values of sensors in the edge area of the metal strip whose measurement area is not covered completely by the metal.

Method and device for measuring the tensile stress distribution in a metal strip

A method for measuring the tensile stress distribution over the width of the metal strip is provided. In order to measure the tensile stress in a metal strip between two roll stands or between a roll stand and a coiler or a guide roll, a force is exerted on the metal strip using a suction device and effecting a deflection of the metal strip. The deflection of the metal strip is measured and used for calculating the tensile stress distribution over the width of the metal strip.
