Brief Introduction
Cold-Rolled Steel Coil is steel that has been worked below its 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.
