During cold rolling process the reduction in thickness is due to plastic deformation which occurs by means of dislocation movement. Steel gets hardened because of the buildup of these dislocations. These dislocations reduce the ductility of cold rolled steel making it useless for forming operation.
COLD ROLLED COILS AND SHEETS - JSW Steel Ltd
Cold Compact Mill (CCM) Pickled coils are rolled in twin stand cold rolling mill where they are processed into a specified thickness. Generally, the rolling reduction ratio is 50% to 90%. The critical point at this stage of the process is to maintain uniform and precise flatness throughout the entire length of the coil. Unique Features

From Cold-Rolling to Annealing. Pickled coils are rolled to the specified thickness . by cold rolling. The Cold-Rolled Steel Sheets and Coils have their crystal grains enlarged in the rolling direction, making the texture hardened and brittle. In the annealing process, the coils are continuously heated in reductive atmospheric gas to form uniform
Cold Rolled and Spheriodized Annealed Steel Strips ...
Cold Rolled Steel Strip is produced, as the term suggests by the further rolling of strip produced by the hot strip mills. Prior to cold rolling, the mill scale has to be removed, normally by the Pickling Process which uses mechanical manipulation (around small diameter rolls) and acid to dissolve the surface scale.
New Rolling Method Of Reversing Cold Rolling Mill
For the production of cold rolling steel strips in a yearly production capacity range from 150,000 to 300,000 tons, a reversing cold rolling mill, which requires relatively minimal capital investment, is put into use. The reversing cold rolling mill is used mainly for producing coils of ordinary carbon steel in

Cold rolling is a work hardening process used to change the structure of metals and is often used to process stainless steel. Cold rolled stainless steel as a raw material has a wide variety of applications in medical, aerospace and automotive engineering.
Introduction to Rolling Process
1.2 Hot and Cold Rolling Processes From metallurgical point of view, rolling process can be classified under two broad categories, namely (i) hot rolling and (ii) cold rolling. 1.2.1 Hot rolling In hot rolling the material is rolled at a temperature higher than its recrystallization temperature. The advantage of hot rolling is twofold.
