International quality standards SPCD cold steel Introduction
Using International quality standards SPCD cold steel 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 20-40 tons, and the hot-rolled pickled coil is continuously rolled at room temperature. The inner diameter is 610mm.
