What is Cold Drawing? (with pictures)
Cold drawing is a metal forming process whereby a piece of metal is forced through a single or series of dies, thereby reducing the cross section size of the original part. The cold drawing process yields a dimensionally consistent final product, while improving both yield and tensile strength. The resulting surface is clean and free from scale ...

A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING MILL ROLLS
on wear is another issue. Stresses from Hertzian pressure in 4high cold mill back up rolls were measured years ago, the results were never published, but of high interest also, maybe later. K. H. Schröder July 2003 K. H. Schröder: A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING MILL ROLLS File: SCHROEDER_ROLLS_
Rolling processes
rolling rather than cold rolling to reduce strength and strain hardening (K and n) of the work material; (2) reducing the draft in each pass; (3) using a smaller roll radius R to reduce contact area and then reduce the force; and (4) using a lower rolling speed N to reduce power. Shape rolling:

Cold Pilger Rolling: Part One :: Total Materia Article
Figure 1: The scheme of cold pilger rolling. The two most common ways to coldreduce tubes by compression are VMR1 and HPTR2 cold pilgering mills. Although both VMR and HPTR dies reduce tubes via compression rather than tension, the complexity of tooling design and manufacturing varies greatly between these machine types.
