Logics of Roll Pass Design

In an attempt to maintain simplicity in roll geometry, the complexity of rolling mills has been increased over the years, encouraging the development and application of various types of the universal mill stands and other complex constructions. The key to understanding roll pass design (RPD) is to be found in the deformation zone.
