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 34 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.

2. Outline of Reversing Cold Rolling Mill (1) Outline of reversing cold rolling mill and rolling method As illustrated in Figure 1, a reversing cold rolling mill is comprised mainly of a mill proper, a winding machine (payoff reel), an entry winding machine (entry tension reel) and delivery winding machine (delivery tension reel).
Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill "sees" instantaneously unless some damping system such as a surge hopper is used.

Nov 09, 2013 · During cold rolling process the reduction in thickness is due to plastic deformation which occurs by means of disloion movement. Steel gets hardened because of the buildup of these disloions. These disloions reduce the ductility of cold rolled steel making it useless for forming operation.
