What is Cold Rolling? (with picture)

Cold rolling can be used to change the gauge of steel sheet metal. Cold rolling is a process used in manufacturing and finishing environments to change the thickness, or gauge, of metals or glass. Used mostly in steel mills, cold rolling involves threading flattened steel into a machine that advances the material through a set of rolls.

Introduction to Rolling Process

2 Principles and Applications of Metal Rolling (ii) Shape of the rolled product- flat, sections or hollow sections rolling. (iii) Direction of rolling- lengthwise, transverse, and skew rolling. (iv) Mode of rolling mill operation- continuous (unidirectional), and reverse rolling, where direction of rotation of rolls are reversed. When two rolls of equal diameter and with axis lying in same ...

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.
