![Rolling Mills: 6 Different Types of Rolling Mills [Images PDF]](/ktbo0xj/394.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 ...

Roll bending process. The Roll Bending (RB) process, also referred to as "plate rolling", as opposed to the JCO and UO pressbending processes, is performed with a pipe rolling machine. This consists of a set of three or four rollers, positioned in a "pyramid" configuration to bend the plate into a pipe (Fig. ).
