through the grains of the metal, the rolling of threads causes improved strength, because of cold working and favorable grain flow. Figure 13.15 Thread-rolling processes: (a) and (c) reciprocating flat dies; (b) two-roller dies. Threaded fasteners, such as bolts, are made economically by these processes, at high rates of production.

Sheets less than 1.5–3 mm thick are best cold-worked, and thus the sheets are usually further reduced in thickness in cold-rolling mills. After the reels are obtained from the continuous hot-rolling mill, they are transported to the cold-rolling unit, where scale is removed from the surface of the metal in a continuous pickling line.

4-High Rolling Mills. Four-high rolling mills can be put in tandem, two to seven stands, instead of a reversing mill. They can be equipped with load cells to tell the separating force and hydraulic or mechanical screw downs, depending if it is hot or cold rolling. Sometimes mechanical screw downs are preferred when there is a risk of fire.
