Rolling processes 5-1 introduction: Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (5-1). Fig. (5-1) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.

Cold Rolling an overview ScienceDirect Topics

Cold rolling reduction is an important factor that affects drawability of IF steel. It has been observed that increasing cold rolling reduction increases the r m value, at least up to 90% [34].This effect has been shown in Fig. 5.14.Perhaps the most important parameters in the production of a strong {111} recrystallization texture are the annealing temperature and the time of holding [35].
