In simple terms, cold rolling is the process of strengthening steel by changing its shape without using heat. 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.

However, roll shifting is difficult for a fully tandem cold rolling mill when the welded coils are rolled continuously and the roll shifting is conducted under the condition of a large rolling load [10], [11]. Due to the existence of a rolling load and friction in the contact zones among work roll, backup roll and strip, the thrust force occurs.

Cold rolling mills also operate at considerably higher rolling speeds of sometimes above 2,000 m/min, and entry and exit tensions are applied to the strip to assist the deformation. In the cold rolling operation, the high specific loads lead to considerable roll flattening and bending. With smaller reductions and thinner strip, the elastic ...
