Chat OnlineRolling processesAl-Mustansiriya University
Rolling processes 5-1 introduction Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls as shown in figure (5-1). Fig. (5-1) Most rolling is carried out by hot working called hot rolling owing to the large amount of deformation required.
Chat OnlineWhat is Pilgering Pilger Mill Technologies
When producing large quantities of tubing cold drawing is considered to be very slow compared to the pilgering process. As an example a cold drawn tube may have to be drawn 3-4 times to equal the same amount of work of a pilger mill. Each time a tube is cold drawn the tube must be cleaned and annealed (softened) before drawing again.
