摘　　要：CVC mills are generally used in the whole stands of CSP（Compact Strip Product）.Their special ＂s＂ curve of work roll contour and shifting strategy aimed at controlling strip shape,and the characteristics of continuous casting and rolling production,which make the work roll wear in downstream stands seriously uneven,and easily form abnormal transverse profile at the rolling end.As a result,CVC mill configuration in the downstream stands can not meet the profile and flatness control requirement for schedule free rolling,and bring some difficulties in profile and flatness control for the subsequent cold rolling.Based on the characteristics of the shape control system of CSP production line,and combined with the theory of flat roll technology,a kind of technology solution of using flat roll in the downsteam stands for CSP hot strip mills was proposed.At last,industrial test was carried out in the last stand of Masteel CSP,and good results were obtained.CVC mills are generally used in the whole stands of CSP（Compact Strip Product）.Their special ＂s＂ curve of work roll contour and shifting strategy aimed at controlling strip shape,and the characteristics of continuous casting and rolling production,which make the work roll wear in downstream stands seriously uneven,and easily form abnormal transverse profile at the rolling end.As a result,CVC mill configuration in the downstream stands can not meet the profile and flatness control requirement for schedule free rolling,and bring some difficulties in profile and flatness control for the subsequent cold rolling.Based on the characteristics of the shape control system of CSP production line,and combined with the theory of flat roll technology,a kind of technology solution of using flat roll in the downsteam stands for CSP hot strip mills was proposed.At last,industrial test was carried out in the last stand of Masteel CSP,and good results were obtained.
