2015-11-19 · 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.

This process is vastly used in respect of any other rolling process. In this process, the metal is heated above the recrystallization temperature.In the hot working process, the metal is changing its grain structure because of the heat, now there were a new set of strain-free grains in the metal and this process needs less amount of force which correspondingly reduces the quality of the ...
