![Rolling Mills: 6 Different Types of Rolling Mills [Images PDF]](/qk56sdb/413.jpg)
In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change its crosssectional area.. The types of rolls used in rolling mills are depended upon the shape, size, and the gap between the rolls and their contour. Because of workability and limitations in equipment, rolling is done in the ...

The material properties of the strip play a vital role in the power consumption and the damage evolution in a tandem cold rolling mill. Therefore, the strip tearing or power consumption level of importance is not the same for different materials. Besides, various reduction schedules can be proposed for the specified total reduction and initial strip thickness in the tandem cold rolling process ...
