Abstract：1550mm tandem cold mill in Baosteel was used as the study platform. This paper focused on the improvement of control capability of strip flatness and reduction of roll consumption in UCMW cold tandem mill which is a international mainstream mill type. It is proposed that intermediate roll profile technology which give consideration to evening axial distribution of contact force between rolls & decoupling thought and work roll profile technology which can improve strip edge drop control . control capability of strip flatness was increased, mill type of this UCMW tandem cold mill was improved to some extent. Edge drop and stripe flatness of silicon steel was improved after the modification, control objective had been realized, good effect had been brought about in application.
