Roll Bending - an overview | ScienceDirect Topics
The fabrication and structure of a 2-DOF spring roll is illustrated in Fig. 9.3 and described in Section 9.2.1. Figure 9.7 schematically shows the bending of a 2-DOF spring roll caused by a stroke, S, in the actuated circumferential span between points a and b [2]. It is assumed that the bending roll forms a curve with a constant curvature.

Technological control for cold rolling processes
rolling (e.g. due to thermal effects, wear, loading, etc.) is implemented. Tension feed-forward control The tension feed-forward control responds to entry thickness deviations and applies a suitable adjust-ment to the coiler torque in order to consider the in-teractions between roll gap and tension.

6/21/2009· Four-high mills are mainly used for rolling foils, sheets and plates and account for a large percentage of all mills. The speed of contemporary four-high mills has reached 1800–2200 m/min to meet demands for rolling of foils and sheets. However, frequent burning of end-thrust bearings in the work-roll assembly can disrupt the production process.
