A method for determining the tensile strength of a strip in a straightening machine and enhancement of the - soft-sensor

摘要

The present invention relates to a method and corresponding soft sensor for determining the tensile strength of a strip in a straightening machine, such as, for example, a the form of end of the bending machine or stretch-leveler machine. In the method, the process variables strip tension of the straightening machine, depth of immersion of the straightening rollers, degree of stretch of the strip, and belt geometry of the belt. On the basis of the determined process variables, the tensile strength of the band determined by means of model calculation.
