This book discusses as well the different types of rolls for various rolling mills, including blooming, plate, sheet, sheet bar, small section, heavy product, skin passing, and cold rolling mills. The final chapter explains the purpose of roll pass design to ensure the maximum output at minimum cost as well as to reduce the roll wear to a minimum.
Roll pass design is an essential part of long product rolling process, since the long products are rolled between the shaped rolls in the long product rolling mills. Roll pass design generally means the cutting of grooves in the roll body through which steel to be rolled is made to pass sequentially to get the desired contour and size. The ...

ROLL PASS DESIGN. IN CONTINUOUS BAR MILLS Department of Metallurgical and Materials Engineering INDIAN INSTITUTE OF TECHNOLOGY KHARAGPUR Basic Terminology •Two facing grooves form a 'roll pass', or simply a 'pass'.. The distance between the barrels of two rolls is called the 'nominal roll gap', or 'theoretical roll gap'.
Beynon (1956) presented a typical roll pass design for T-bars, and Brayshaw (1958) showed more examples including special T-sections. Three-roll mills are sometimes applied to T-bar production. For example, Kyoi et al. (1978) studied the fundamental deformation behavior in three-roll rolling of T-bars.

A tandem mill is a special type of modern rolling mill where rolling is done in one pass. In a traditional rolling mill rolling is done in several passes, but in tandem mill there are several stands (>=2 stands) and reductions take place successively. The number of stands ranges from 2 to 18.
The foundation of a successful rolling mill operation is a fine tuned pass design. The pass design is created based on your specific mill layout and product requirements. Quad has improved productivity and quality simply by modifying or replacing existing pass designs.
The typical mill layout for such a rolling mill is at Fig 2. The universal roughing and edging mills are reversing multiple pass mills that run in tandem through computerized speed matching. The universal roughing mill is normally a four-roll mill with two driven horizontal rolls and two non-driven vertical rolls.
