Abstract: In view of shape control problem of nuclear zirconium alloy strips during the multi-roll and multi-pass cold rolling process. The integrated three-dimensional finite element model of nuclear zirconium alloy strip and roll systems is established. A design method of VCR (varying contact backup rolls) based on particle swarm optimization is proposed. Combining field practice, the automatic optimization iterative design is suitable for the roll contours of the VCR technology during multi pass rolling of nuclear power zirconium alloy strip. Finite element simulation results show that:Compared with the existing industrial scheme of nuclear zirconium alloy strip, the shape control ability of the new scheme is obviously enhanced. The new scheme can effectively eliminate the undesired contact areas between the backup roll and work roll and reduce the length of the undesired contact line length between the rolls by 87.58%, increase the roll gap stiffness of the roll system by 17.55%, and increase the regulating efficiency of the bending force by 15.15%. This provides a theoretical basis for industrial tests aimed at improving the shape quality of nuclear zirconium alloy.
