Backup roll technology plays an important role in hot strip mill shape control. Varying contact length backup roll (VCR) technology in hot strip mill can increase transverse stiffness of loaded gap, heighten control effect of roll bending, and improve distribution of contact force between backup roll and work roll. However it appears to lack coordination with high-order curve work roll. A new objective function of new generation varying contact length backup roll (VCR plus) design curve is established with considering high-order work roll contour, and simulation is carried out to verify the effectiveness of VCR plus by a two dimensional variable thickness finite element method. The result shows that distribution of contact force between backup roll and work roll is more even in VCR plus technology, and which can extend the useful life of backup roll.
