What is the meaning of skin passed of hot-dip galvanized steel coil?

Answer: With the continuous expansion of the use of hot-dip galvanized sheet, in the modern continuous hot-dip galvanizing equipments, the following purposes can be achieved by smoothing the strip:

①Improve the straightness and flatness of the sheet, and at the same time, it can also flatten the zinc particles on the surface to make the surface of the strip smooth, which is particularly beneficial for future deep drawing and other occasions with high use accuracy;
② The skin-pass roller used has been pre-blasted, so the surface of the smooth-plated plate has a certain roughness. It can improve the adhesion of the coating, and can also store a certain amount of grease, which is beneficial to the lubrication of the die during deep drawing;
③ For the plated sheet that is later painted, although the surface is controlled into small spangles, the small spangles can still be revealed through the paint layer. Therefore, for some galvanized sheets with high requirements, the surface of the small spangles needs to be smoothed. This allows the galvanized sheet to obtain a more uniform silver-white appearance;
④Through smoothing, the lower yield point can be reduced, the yield platform disappears or is less obvious, which can prevent the slip line from appearing in the later drawing or deep drawing, and improve the possibility of deep drawing.
