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.

Ring rolling is a specialized type of hot rolling that increases the diameter of a ring. The starting material is a thick-walled ring. This workpiece is placed between two rolls, an inner idler roll and a driven roll, which presses the ring from the outside. As the rolling occurs the wall thickness decreases as the diameter increases.
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.
