Introduction. Being the most widespread metal forming process, strip rolling (pictured schematically in Fig. 1) has received intensive attention from mechanical engineers since the beginning of the previous century: successful attempts at solving simplified mechanical equations to disclose the mechanics of cold strip rolling can be traced back to 1925 at least [1].

Strip cold rolling is a technology for metal sheet and strip rolling below recrystallization temperature. The raw material is usually hotrolled steel strip or plate which is rolled by a cold rolling mill at normal temperature to produce steel profiles. Coldrolled strip steel and steel sheet have advantages, such as smooth surface, high ...

Cold rolling, unlike hot rolling such as with hot rolled steel, can only occur when a metal is below its recrystallization temperature. Where hot rolling is performed using high temperatures, cold rolling is performed at room temperature. Instead of heat, mechanical stress is used to change the structure of metal.
