12/01/2022 · During hot rolling, the incoming rough strip in front of the finishing mill is automatically detected and automation failures resulting in errors and downtime are a risk. A standstill in production causes considerable costs due to loss of material and time. This can lead to material being devalued - and in the worst case - removed from the plant.
Center Buckling. This defect occurs due to the self-equilibrating residual stresses that result from the rolling process. During center buckling, fibers at the center of the metal piece are longer than those at the edges. In an event where hot or cold mills have too much crown, mills roll out at the center. Sideways deflection of a structural
