Modeling of thin strip profile during cold rolling on roll crossing and shifting mill

Strip profile control in cold rolling of thin strip is a difficult and challenge problem

found in industry. Currently using the novel type of strip rolling mill, such as the work roll

crossing and shifting is the one of the main methods to control the strip profile quality in cold

rolling. In this paper, 3-D finite element simulation models of the thin strip profile in cold rolling

for the work roll crossing and shifting system were successfully developed. The strip profile and

edge drop are discussed considering both crossing angle and shifting value of the work rolls. The

research shows that the combination of the work rolls crossing and shifting can effectively

improve the strip profile. The developed 3D- finite element model has been verified with the

measured values. The obtain result are applicable to control the rolled thin strip profile during

cold rolling process.
