What's the meaning of "double light" in strip cold rolling?

Answer:

Strip strip coiling: general supply, with high dimensional accuracy, good surface quality, easy processing, material saving and other advantages. With the same steel plate, strip by strip material is divided into ordinary and high quality strip two; according to the processing method of cold rolled strip steel hot strip, two.
Double light: This is generally cold rolled roll of the statement, cold-rolled grades SPCC, SPCC is generally a general term, including SPCC-SB, SPCC-SDSPCC-SD is a single light, it is now generally rough surface is the material directly labeled SPCC, remove the suffixSPCC-SB is double light, the surface is mirror surface, also called bright surface
Cold: cold rolled steel is cold-rolled steel production. Cold rolling at room temperature under the conditions of No.1 steel plate further rolling thin thickness steel plate. Compared with hot-rolled steel, cold-rolled steel plate thickness is more accurate, and the surface is smooth and beautiful, but also has superior mechanical properties, especially the processing performance because of cold rolled. The volume relatively brittle and hard, not suitable for processing, so typically cold rolled steel demand after annealing, pickling and smooth surface will be delivered to customers. The maximum thickness of cold rolling is below 0.1--8.0MM, most of the factories such as cold rolled steel plate thickness is below 4.5MM; minimum thickness, width is according to the plant equipment capacity and market demand and decision.
