Multi-high rolling mills are used particularly in the manufacturing of very thin sheets of thickness about 0.01 mm and width up to 2000 mm. In this case, the working rolls must have very small diameter, usually 10 mm to 30 mm. Such small diameter working rolls make a drive practically impossible.
finishing mills, which will roll the steel in tandem with one another. The workhorse roughing mill has 135 wide rolls for rolling broadside as the first roughing mill is commonly called to make a slab wider. A 5,000 hp motor drives 42-diameter work-rolls through 281 gears to reduce the slabs thickness by
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.
