The Plate-Steckel Mill is a highly specialized hybrid, capable of rolling wide structural steel products in both flat plate and coil form, and at very long lengths through the use of coiler furnaces. There are few examples and even fewer truly successful project references, with Primetals Technologies prominent as a proven supplier.

In some mills (e.g. hot strip mill, wire rod mill, merchant mill, and cold rolling mill), the rolled product is coiled in a coiler or a wind up reel. Mostly, rolling is done at high temperature, called hot rolling, because of requirement of large deformations. Hot rolling results in residual stress-free product.
rolling mill, dedicated roll cooling systems are required to fulfill the required functions. Examples are suitable roll cooling and lubricationsystems to fully utilize the advantages of HSS rolls in hot strip mills, and selective roll cooling systems as a method to control the flatness of the strip in cold rolling mills.

A typical hot rolling mill consists of a reheat furnace, sizing press, roughing mill, finishing mill, runout table and coiler, as shown in Figure 1. Among these components, the finishing mill, which is composed of two work rolls (WRs), two intermediate rolls (IMRs) and two backup rolls (BURs) supporting them, has a major influence on the ...
The control problem of the hot-steel rolling mill is thus formulated in two levels: (i) from to one computes the control inputs and that should be applied to the hot-steel roll mill system so as to assure that the angle of the looper and the tension on the strip will reach the desirable setpoints, (ii) the control inputs and become setpoints ...

3. • Rolling is the process in which the metals and alloys are plastically deformed into semi finished or finished condition by passing between circular cylinders. • Due to the frictional forces the metal is drawn into the opening. • Metal Changes its shape due to high compressive forces. • Both hot (for drastic shape changing) and cold ...
METAL FORMING SCIENCE AND PRACTICE The flattening rate W is a function of the real area of contact area ratio A and the ratio p Y of the mean contact pressure to the plane strain yield stress of the strip, i.e. = A Y p W W, (4.4) The theoretical flattening rate W is in the range 1–8, increasing with increasing mean pressure and falling with increasing area of contact ratio.
Fig 4 Roll configurations in rolling mills. Two-high mill roll configuration – This is the most commonly used rolling mill configuration. In this configuration, there are two horizontally mounted rolls. The rolling mill motor drives either both rolls (top and bottom) or only one roll (normally the bottom roll) with the top roll rotating due to the friction between the roll and the …
