Abstract：The configuration of conventional backup and work rolls for revamped 1700 tandem cold rolling mill at WISCO was proved unreasonable by systematical test as the cause of work roll edges contact during thin strip rolling and unsatisfactory flatness of product. A 2dimensional varying thickness finite element model of roll system deformation was built to simulate and analyse rolling process, and then a VCR (varying contact backup roll) was designed for the rolling conditions of PLTCM (pickling line combined with tandem cold rolling mill) and has been applied to 1700 tandem cold rolling mill at WISCO after industrial test. The application of VCR improves shape control,giving better strip flatness, higher capacity for thin strip and better selfmaintenance of roll contours.
