Tandem Rolling Process :: Total Materia Article

Tandem rolling can be even more advantageous when integrated with continuous casting. The tandem cold rolling process is composed of treading, acceleration, run speed operation, deceleration and tailing out. Figure 3 illustrates a typical speed diagram for tandem cold rolling. It shows the threading is the first phase of the rolling.
