Cold-rolled coil:
Using hot-rolled steel coil as raw material, after pickling to remove oxide scale, cold rolling is carried out.
Continuous rolling, the finished product is a cold-rolled coil. Due to the cold work hardening caused by continuous cold deformation, the strength, hardness and toughness and plastic index of the hard-rolled coil increase, so the stamping performance will deteriorate, and it can only be used for simple deformed parts. Cold-rolled coils can be used as raw materials for hot-dip galvanizing plants, because hot-dip galvanizing lines are equipped with annealing lines. The weight of rolled hard coil is generally 6~13.5 tons.
