2. Rolling Mill classification Rolling mill is used to reduce successively the thickness of the metal strip as per the requirement. Hot rolling mills are used for mass thickness reduction at high temperatures, whereas the cold rolling mills are used as secondary rolling operations to attain more precise dimensional and mechanical properties ...

Rolling is the most important metal forming process. More than 95% of ferrous and non-ferrous metals and alloys are processed to their usable shapes by rolling. Usable shapes of rolled metals are plate, sheet, strip, foil, different sections like rail, beam, channel, angle, bar, rod, and seamless pipe, etc., as shown in Fig. 1.1 and Fig. 1.2.

This type of rolling mills is used for rolling of continuous passes in a rolling sequence without reversing the drives. This results in a higher rate of production than the two-high rolling mill. Four-high Rolling Mill. Here two rolls are in direct contact with the work-piece and the other two rolls are used as backup rolls.

The roll neck bearing used in a rolling mill is limited in its dimensions by the roll neck diameter and minimum roll diameter. The four-row tapered roller bearing is so designed that its load rating may be as large as possible within this limited space. This type of bearing consists of two sets of cone assemblies, three cups and two cup spacers. To

Fig. 1.2.1: Rolling mills Planetary mill has a pair of large heavy rolls, surrounded by a number of smaller rolls around their circumference. In this mill, a slab can be reduced to strip directly in one pass. Feeder rolls may be needed in order to feed the work piece into the rolls. Merchant mill is specifically used for rolling bars.

The rolling process is a metal-forming process, in which a stock of the material is passed between one or more pairs of rollers to reduce and maintain the uniform thickness. This process is mainly focused on the cross-section of the ingot or the metal which is forming. Using this process, we can reduce the thickness of the metal workpiece.

The more roll pairs the mill has, the greater the size reduc-tion it can achieve. For instance, reducing salt feedstock to coarse road salt requires a roller mill with one roll pair, while reducing the material to table salt requires a mill with two or three roll pairs.
