    what is it ?

    Cold rolled steel plate is an abbreviation for cold rolled sheet of ordinary carbon structural steel, also known as cold rolled sheet, commonly known as cold plate, the thickness of which is less than 4 mm, sometimes misspelled as cold rolled sheet, the minimum thickness of 0.2-4 mm, width of 600-2,000 mm, the length of the steel plate of 1,200-6,000 mm.Cold rolled steel sheet is in great demand in the market, and it has a better application prospect.

    Cold Rolled Steel

    Cold rolled products are divided into hot rolled pickled, rolled hard rolled, ordinary cold rolled, galvanised (electro-galvanized, fingerprint-resistant, hot-dip galvanized), aluminium zinc plated, electro-tin plated, colour coated, electrical steel (silicon steel sheet) and so on.

    Due to rolling at room temperature, no iron oxide is produced, therefore, the surface quality of cold rolled carbon steel plate is good and the dimensional accuracy is high.

    Properties and uses

    cold rolled steel coil

    Cold rolled sheet steel has good cold bending and welding properties, as well as certain stamping properties. Mostly used in automobile manufacturing, electrical products and construction, etc., can also be used in simple deformation of the parts inside, such as industrial small screws and so on.

    Difference between cold rolling and hot rolling

    (1) Hot rolled is through the plate embryo through the roughing mill and finishing machine after heating steel, let a finishing mill output hot rolled steel layer, after cooling set temperature, and then let the coiling machine into a strip coil, and then cooled again, according to customer demand, choose a different way to process, the normal heating of the steel embryo needs to be rolled many times to cut the edge of the made of steel plate, which is the hot rolled.

    (2) Cold rolled is to take the hot rolled coil as raw material, first pickling to remove the oxide skin, the finished product for the hard roll, because of the continuous cold deformation makes the hardening, its strength, hardness can be improved, but the toughness and plasticity will also be reduced, so the stamping performance will become serious.1725245309127
