A cold-rolled sheet is a sheet made by rolling a hot-rolled coil as a material and rolling below the recrystallization temperature at room temperature.
In the entire process of cold-rolled sheet production, because no heating is performed, there are no defects such as pits and scales often present in hot rolling, and the appearance is good and the finish is high. And the cold rolled products have high scale accuracy, and the functions and arrangements of the products can meet some special application requirements, such as electromagnetic functions and deep drawing functions.
Cold-rolled sheet has a very outstanding function, that is, cold-rolled strips and steel sheets with thinner thickness and higher accuracy can be obtained after cold rolling, with high flatness, high surface finish, clean and bright appearance of cold-rolled sheet, and easy to apply.
There are many types of plating, and they are widely used. Together they have the features of high stamping function, no aging, and low yield point. Therefore, cold-rolled plates are widely used. They are mainly used in cars, printed iron drums, construction, building materials, bicycles and other occupations. Together, it is still the best choice for producing organic coated steel sheets.
