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.
