Towards a better width control in cold rollingof flat steel strips
Published online by Cambridge University Press: 26 August 2006
Abstract
Strip width necking may be quite significant on cold rolling mills. To compensate for this unpredicted phenomenon, hot strips are often ordered with an over-width with resulting substantial over costs, for trimming in particular. Based upon numerical simulation supported by rolling trials, the main factors that effect strip width variation have been quantified: edge drop, transverse stress relaxation, thermal contraction. Potential width actuators to be implemented on industrial cold rolling lines have been identified.
