Cold-based hot rolled coil as raw materials for a variety of profiles rolling, cold-rolled steel production of cold-rolled steel plate is through, commonly known as the cold plate at room temperature. Cold rolled sheet thickness is generally between 0.1-8.0mm. Features: Since there is no annealing, the high hardness (HRB greater than 90), poor machining performance, only a simple directional bending less than 90 degrees (perpendicular to the winding direction). Because relatively brittle cold rolled coil, not suitable for processing, so under normal circumstances require annealed and cold-rolled steel surface smoothing treatment. Cold-rolled steel sheet is ordinary carbon steel cold rolled sheet for short, is the ordinary carbon steel hot rolled strip, after further cold rolling steel plate having a thickness of less than 4mm. Due to rolling at room temperature, do not produce iron oxide skin, therefore, good cold surface quality, high dimensional accuracy, coupled with annealing treatment, the mechanical properties and process performance are better than hot-rolled sheet steel, in many areas of Tianjin metal file cabinet, especially in the field of home appliances manufacturer, has been gradually replaced by its hot-rolled steel sheet. Quality cold-rolled steel sheet includes a variety of high quality cold-rolled steel sheet, the most common is carbon structural steel, especially deep drawing cold rolled sheet steel, is made of a thin cold-rolled carbon quality steel 08Al, the steel surface quality by points into three groups; Ⅰ, Ⅱ, Ⅲ Xi'an metal file cabinets, were particularly high, high, high surface finishing, according to drawing level is divided into ZF, HF, F grade (on behalf of Punch drawing the most complex very complicated, complex parts), according to the plate thickness tolerance, is divided into A, B two precision, widely used in automobile and tractor industries.
