Cold-rolled:hot-rolled steel coil for raw material, after acid pickling to remove oxide skin for cold rolling, the finished product is hard roll, because of cold work hardening caused by deformation of continuous cold rolling hard roll strength, increase hardness, toughness and plastic index decreased, so the stamping performance will deteriorate, can only be used for simple deformation of the parts. Hard coil can be used as a raw material, hot dip galvanized factory for hot dip galvanizing unit Settings are annealed wire. Hard coil weight generally in June to 13.5 tons, steel at room temperature, for continuous rolling of hot rolled pickling volumes. Inner diameter is 610 mm.
