recrystallization temperature by passing it between a pair of rollers.
Recrystallization temperature is the temperature at which grains in the
lattice structure of the metal have been rearranged, leaving it free of
strain and deformations. Cold Rolled Steel Coil is pre- treated before
being cold rolled with a process known as pickling, which uses strong
acids to remove scale and other impurities. The Cold Rolled Steel Coil
is then passed through rollers to reduce its thickness. Most cold
rolling takes place in multiple passes and as the size of the Cold
Rolled Steel Coil is further reduced, its strength and hardness both
increase, but its ductility decreases. After cold rolling, heating the
metal up in a process known as annealing can restore some of its
ductility. The final Cold Rolled Steel Coil may be manufactured in the
form of sheets, strips, bars, or other forms.
