Cold plate is the abbreviation of ordinary carbon structural steel cold-rolled plate. It is also called cold-rolled plate, commonly known as cold plate, and is sometimes mistakenly written as cold-rolled plate. Cold plate is a hot-rolled steel strip made of ordinary carbon structural steel, which is further cold-rolled into a steel plate with a thickness less than 10%. Since rolling at room temperature does not produce iron oxide scale, the cold plate has good surface quality and high dimensional accuracy. Coupled with annealing treatment, its mechanical properties and process performance are better than hot-rolled thin steel plates. In many fields, especially In the field of home appliance manufacturing, it has gradually been used to replace hot-rolled thin steel plates.

Symbol
, the code for the yield point (limit) of ordinary carbon structural steel, which is the uppercase and lowercase letters of Qu in Chinese Pinyin. The numerical value that represents their yield point (limit), unit MPa. Since the comprehensive mechanical properties of steel such as strength, plasticity, toughness and weldability are the best among ordinary carbon structural steels, it can better meet general usage requirements. The range of applications is very wide.

Cold rolled ordinary Thin steel plates are cold rolled from ordinary carbon structural steel or low alloy structural steel. The surface quality of cold rolled plates is better. Has good stamping performance. Its requirements must ensure that the cold bending and cup tests are qualified. It is often used in automobile and other industries and as raw materials for coated plates.
Cold-rolled high-quality thin steel plates mainly include various high-quality steel cold-rolled thin plates. The most commonly used are carbon structural steel plates, especially cold-rolled thin steel plates for deep drawing. They are cold-rolled thin plates of low-carbon high-quality steel. Steel plates According to the surface quality, it is divided into three groups: I, II and III, which respectively represent particularly high-grade, advanced and higher finishing surfaces. They are divided into grades according to the drawing level (representing the most complicated, very complicated and complicated drawing for punching and drawing). Parts), according to the allowable deviation of the thickness of the steel plate, it is divided into two levels of accuracy, and is widely used in the automobile and tractor industry.
Cold-rolled steel plate, with smooth surface and excellent processing, is used in automobiles, refrigerators, washing machines and other home appliances, as well as industrial equipment and various building materials. With economic development, cold-rolled steel plates have been called a necessary material in modern society. Classification of cold-rolled products: hot-rolled pickling, hard-rolled coils, ordinary cold-rolled, galvanized (electro-galvanized, fingerprint-resistant, hot-dip galvanized), aluminum-zinc plating, electro-tin plating, color coating, electrical steel (silicon steel sheets), etc. . , Hot-rolled pickling
, Hard-rolled coils are continuously rolled on hot-rolled pickled coils at room temperature.
Product Features Because it has not been annealed, its hardness is very high (greater than 100%) and its machining performance is extremely poor. It can only perform simple directional bending of less than 10% (perpendicular to the coiling direction).
