The invention of the rolling mill in Europe may be attributed to Leonardo da Vinci in his drawings. The earliest rolling mills in crude form but the same basic principles were found in Middle East and South Asia as early as 600 BCE. Earliest rolling mills were slitting mills, which were introduced from what is now Belgium to England in 1590.
Jul 11, 2006· The cold mill pilgering process uses ring dies and a tapered mandrel to reduce tube cross sections by up to 90 percent. Because the process relies on large number of small forming steps, the result is tube or pipe that has nearly homogenous material characteristics. It is suitable for every metal.

practical process of radial-axial ring rolling, keeps at the range of 400 - 1600 mm/s [6]. Neglecting the relative sliding between the main roll and ring, one obtains: RRR VTA (11) where R is the rotation speed of the main roll, RR is the radius of the main roll and VTA is the linear speed of the ring.

It is known, in metal rolling practice, that the amount of roll force is reduced with a smaller radius of the rolls. Smaller radius rolls, however, deflect easier and must be supported by other rolls. The four high mill uses this principle with two smaller work rolls each supported by a larger backing roll.
