harsh_10. This document discusses the basics of roll pass design for rolling mills. It describes the components of a rolling mill, which consists of at least two cylindrical rolls used to shape and reduce the cross-sectional area of metal stock. Roll passes can be definite, having two equal axes, or intermediate, having one larger axis.

Flat rolling of plates and sheets is essentially a plain-strain compression. f1.2. Roll Pass design for steel The cross sectional area is reduced in each pass and the form and size of the stock gradually approach the desired profile. Here the thickness of the metal being rolled is reduced in each pass by decreasing the distance between the rolls.
