Abstract For high-grade cold-rolled steel strip continuous rolling six-high cold rolling mill，in order to make the strip flatness control performance to adapt to changes in material specifications，most of the intermediate rolls adapt the traverse technology. However，intermediate roll shift will make the contact pressure distribution between rolls more uneven，resulting in a contact pressure peak. During the roll shift process，the contact pressure between the rollers and the sliding resistance will change with the change of traverse speed，and may result in the contact pressure between rolls at the ends of the roll to form a larger pressure peak，wearing the rolls unevenly and shortening the life cycle of the roll. In the current study，a finite element simulation model was built to obtain the variation of contact pressure between rolls during the process of the intermediate roller traversing. The optimization design of roll shape and the use of asymmetric bending force method were proposed to achieve a uniform distribution of the inter-roll contact，reduce the contact pressure peak between rolls，and extend the service life of the roll.
