Abstract Scope |
Inter-roll thrust force due to roll misalignment in 4-high strip rolling mill affects difference in roll forces measured by load cell on the work side and that on the drive side. Since the roll force difference is utilized for strip steering control, in which roll gap tilting control is done assuming the roll force difference reflects strip off-centering behavior, the inter-roll thrust force gives serious disturbance to the steering control, and may cause troubles like tail crash. In this paper, an inter-roll thrust force decoupling method for the steering control is proposed. The method utilizes measured thrust counter forces acting against work roll chocks to obtain effective roll force difference for the steering control. Validity of the decoupling method is confirmed using a laboratory 4-high mill which can control cross angles between rolls and measure the work roll thrust counter forces. |
