The roll shape reconstruction strategy was put forward， that upstream stands still use existing CVC series mill to make the best of CVC mill's strong control ability of shape， plate crown and edge drop， the working roll and back-up roll are still plain barrelled roll， the middle part of intermediate roll adopt plain barrelled roll， the edge part of intermediate roll adopt optimized roll crown， for the shape and surface quality defects which are caused by over- size partial roller pressure and uneven abrasion when the series of CVC mill are used in the productive process of high-end product of tandem cold rolling mill of Baosteel， at the basis of simple analysis for the mainstream models and their merit and demerit of tandem cold rolling mill， based on lots of field experiments and theoretical research， fully thinking the equipment and production craft characters of tandem cold rolling mill， fully absorbing advantages of German CVC series mill and Japanese HC series mill. Good effects are achieved in field test. The shape and sur- face quality of high-end product are improved effectively. Roll consumption decreased evidently.
