Cold Rolled Steel Cold Rolled Steel ODM Smooth Surface Cold Rolled Steel

1.What is cold rolled steel?
Cold rolled steel is steel produced by cold rolling. Cold rolling is a steel
sheet obtained by further thinning the No. 1 steel sheet to a target thickness
under room temperature conditions. Compared with hot-rolled steel sheet, cold-
rolled steel sheet has more accurate thickness, smooth and beautiful surface,
and also has various superior mechanical properties, especially in terms of
processability. Because cold-rolled raw coils are relatively brittle and hard,
and are not suitable for processing, cold-rolled steel sheets are usually
required to be annealed, pickled and surface smoothed before being delivered to
customers. The maximum thickness of cold rolling is below 0.1--8.0MM, for
example, the thickness of cold rolled steel plate in most factories is below
4.5MM; the minimum thickness and width are determined according to the
equipment capacity and market demand of each factory.

2.How is cold rolled steel processed?
Using hot-rolled steel coil as raw material, after pickling to remove oxide
scale, cold continuous rolling is carried out, and the finished product is
rolled hard coil. The cold work hardening caused by continuous cold deformation
increases the strength, hardness and toughness and plastic index of rolled hard
coil. , so the stamping performance will deteriorate and can only be used for
parts with simple deformation. Hard-rolled coils can be used as raw material
for hot-dip galvanizing plants, because hot-dip galvanizing lines are equipped
with annealing lines. The weight of the rolled hard coil is generally 6~13.5
tons, and the hot-rolled pickled coil is continuously rolled at normal
temperature. The inner diameter is 610mm.
