| Synopsis: To meet customers' demand, precise flatness control has recently been required not only for strip rolling but also for strip processing lines, namely, tension leveling, coating, galvanizing, etc. Strip deformation caused by repeated bending with stretching in the processing line is analysed on the basis of incremental-strain theory for the purposes of designing plant specifications and optimization of operation. The developed calculation program can be widely used for analyses as follows; (1) Calculation of curling and residual stress of strip in longitudinal and width directions after tension leveling, (2) correcting-behavior analysis of edge and center waves of strip during tension leveling, and (3) calculation of strip gutters in the continuous color paint coating line. Calculated results give us a great deal of useful information for preventing curling, improving steepness and reducing residual stress of strip. |
