Metal can be reduced by between 60 and 80 percent through cold rolling, and then can be used in the creation of consumer goods or for use in other industries. Can Metals other than Steel Benefit from a Cold Rolling Mill? Though cold rolling is most often used on steel, many alloys and metals can be cold rolled to change their crystalline makeup.

Oct 01, 2019Zheng et al. (2017) established a spatial vibration model of a six-high cold strip rolling mill based on multi-body transfer matrix method, and demonstrated the vibration characteristics of the mill. Recently, several attempts have been made to analyze chatter characteristics in tandem rolling mills, especially the effect of friction on vibration.

Feb 21, 2014The dynamic model of cold rolling mill based on strip flatness and thickness integrated control was proposed, containing the following sub-models: the rolling process model, the dynamic model of rolls along axial direction, and the compensation model. Based on the rule of volume flow rate, the dynamic rolling process model was built. The work roll and backup roll were taken as elastic

Introduction. The single stand rolling mill governing equation is a non-linear function on several parameters Eq. (1). Any alterations on either of them: input thickness (h i), front (t f) or back (t b) tensions, average yield stress or friction coefficient () will cause alterations on the rolling load (P) and, consequently, on the outgoing thickness (h o).
