Rolling of Metals: Process and Principles (With Diagram)

The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.

Types of Cold Rolling Mills (With Diagram) Metals

ADVERTISEMENTS: Like hot rolling, cold rolling can be done using two-and-four-high roll arrangements. Two types of cold rolling mills commonly used are: (i) Sendzimir mill ADVERTISEMENTS: (ii) Saxl pendulum mill Both of these mills make use of small diameter rolls. The former type makes use of elaborate system of backing rolls of increasing diameter as []

It will be noted that work rolls just in contact with the work-piece are of smallest diameter. These are backed up by 2 intermediate rolls, which in turn are backed up by 3 intermediate rolls and these are finally backed up by 4 biggest diameter final back up rolls. Latter type of mill is similar to the planetary mill.

The distance between the mill rolls can be varied and this gap is known as nip. The speed difference between the rolls is called friction ratio and it allows the shearing action. The back roll moves faster than the front roll; a common friction ratio is 1:1.25. Two roll mill mixing is also known as open mill mixing. 1.3.1.2 Internal mixer

Rolling (metalworking) Wikipedia

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, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is known as hot rolling

Puddling (metallurgy) Wikipedia

Puddling is a step in the manufacture of high-grade iron in a crucible or furnace. It was invented in Great Britain during the Industrial Revolution. The molten pig iron was stirred in a reverberatory furnace, in an oxidizing environment, resulting in wrought iron. It was one of the most important processes of making the first appreciable volumes of valuable and useful bar iron without the use of charcoal. Eventually, the
