In a metal rolling process, rolls, stands, bearings, housing, motors, and other mechanical equipment are all a necessary part of the manufacturing operation. The place where all the equipment for metal rolling manufacture is set up is called a rolling mill. Rolling mills often vary in …
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.
TYPES OF ROLLING MILLS. Different types of rolling mills are described below in brief: Two high mills: It comprises of two heavy rolls placed one over the other. The rolls are supported in bearings housed in sturdy upright frames (called stands) which are grouted to the rolling mill floor. The vertical gap between the rolls is adjustable.

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.
In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in equipment, rolling is done in the ...
Aluminum Rolling Mills HARBOR. Aluminum plates pass through a continuous rolling mill to further reduce plate thickness. The final step for the aluminum sheet is cold rolling, where aluminum sheets are compressed between two rollers, reducing material thickness up to 50%.

A pass-line adjusting mechanism is disclosed in association with the chocks of the lower back-up roll of a four-high rolling mill. The adjusting mechanism includes an axially slidable adjusting member having vertically stepped surface portions corresponding to each lower back-up roll chock, and an inverted channel-shaped support member interposed between the chocks and adjusting member.
mediate rolling mills, the pass line was bent again by 90 degrees to be led to an intermediate water cooling box that was installed to control the property of scale, and then on to the finishing mill. A looper is needed between the newly installed intermediate mills and the finishing mill to absorb speed variation. Since the pass line is set
Tags Rolling Mills; What Is A Rolling Mill? In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.

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.
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. Tandem mills can be either of hot or cold rolling ...
