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.

Project Report on COLD ROLLED STEEL SHEET MANUFACTURING ...
Cold-rolled sheet in coil form is produced by removing rust from hot-rolled sheet by "pickling" it in a weak acid solution, then washing, brushing, drying, oiling and unrolling the sheet and finally performing cold-rolling by passing the sheet through a reducing mill under pressure and winding it into a roll.
