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.

What is Cold Rolling? (with picture)

Cold rolling can be used to change the gauge of steel sheet metal. Cold rolling is a process used in manufacturing and finishing environments to change the thickness, or gauge, of metals or glass. Used mostly in steel mills, cold rolling involves threading flattened steel into a machine that advances the material through a set of rolls.
