Cold-rolled sheet is a product made from hot-rolled coil as raw material and rolled at room temperature below the recrystallization temperature. It is mostly used in automobile manufacturing and electrical products. Cold rolling is rolling at the recrystallization temperature, but it is generally understood as rolling using normal temperature rolled materials.

Cold rolled plate production process:

1. Since heating is not performed during the production process, there are no defects such as pitting and iron oxide that often occur in hot rolling, and the surface quality is good and the smoothness is high. Moreover, the dimensional accuracy of cold-rolled products is high, and the performance and organization of the products can meet some special requirements, such as electromagnetic properties and deep drawing properties.

2. Specifications: The thickness is 0.2-4mm, the width is 600-2000mm, and the steel plate length is 1200-6000mm.

3. Performance: Mainly use low-carbon steel grades, which require good cold bending and welding performance, as well as certain stamping performance.

Galvanized steel strip products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commerce industries. Among them, the construction industry is mainly used to manufacture anti-corrosion industrial and civil building roof panels, roof grills, etc.; the light industry uses it to manufacture household appliance shells, civil chimneys, kitchen appliances, etc., and the automobile industry is mainly used to manufacture corrosion-resistant parts for cars, etc. ;Agriculture, animal husbandry and fishery are mainly used as food storage and transportation, meat and aquatic products refrigeration processing tools, etc.; commercial use is mainly used as material storage and transportation, packaging tools, etc.

Cold-rolled sheet steel is the abbreviation of ordinary carbon structural steel cold-rolled sheet, also known as cold-rolled sheet, commonly known as cold-rolled sheet, and sometimes it is mistakenly written as cold-rolled sheet. The cold plate is a hot-rolled strip of ordinary carbon structural steel, which is further cold-rolled into a steel plate with a thickness of less than 4mm. Because rolling at room temperature does not produce iron scale, the cold plate has good surface quality and high dimensional accuracy. Coupled with annealing treatment, its mechanical properties and process properties are better than hot-rolled thin steel plates. In many fields, especially In the field of home appliance manufacturing, it has gradually replaced hot-rolled steel sheets.
