<p><P>PROBLEM TO BE SOLVED: To provide an exit side shape control method in a cold rolling machine capable of rolling without disturbing a shape even when abrupt disturbance occurs. <P>SOLUTION: A differential tension T<SB POS="POST">di</SB>at an i-th stand exit side of the cold rolling machine equipped with multiple stands is found. An evaluation valueΛ' of an estimated form is calculated by a formula 1 (requirement 1) based on the differential tension T<SB POS="POST">di</SB>. The value is feed-forwarded to the final stand so as to change the reduction leveling amount. The differential tension means a cross directional tension difference at strip both ends. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
