Cold rolled little knowledge

Manufacture, packaging steel strip, steel belt, bluing pack USES is very wide, such as automobile manufacturing, electrical products, locomotives, aviation, precision instrument, canned food, etc. Manufacture, packaging steel strip, steel belt, bluing packing belt, cold-rolled steel sheet is short for ordinary carbon structural steel manufacture, also known as manufacture, commonly known as the cold plate, are sometimes mistakenly written as cold plate. Cold plate is made of ordinary carbon structural steel hot-rolled steel belt, after further made from cold rolled steel plate thickness is less than 4 mm. Due to rolling at room temperature, do not produce iron oxide, therefore, the surface of cold plate is of good quality and size precision is high, coupled with annealing treatment, the mechanical performance and the performance is better than that of the hot rolled sheet steel, in many fields, especially in home appliance manufacturing areas, has been gradually replace the hot rolled steel sheet with it.
