  • Rolling processesAl-Mustansiriya University

    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.

  • Difference Between Hot and Cold Rolled Steel Metal

    Sep 11 2014 · Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F) which is above the steel s recrystallization temperature. When steel is above the recrystallization temperature it can be shaped and formed easily and the steel can be made in much larger sizes.
