Improve the flatness of the sheet, remove the zinc particles on the surface to make the strip surface more smooth, improve the surface quality and precision of processing products.<br />
The use of wool finishing, increase the surface roughness of the steel coil, improve the adhesion of the surface coating.<br />
The lower yield point can be reduced by skin passed, so that the yield platform disappears or becomes less obvious, and the slip line can be prevented during the process of drawing or deep drawing, so as to improve the performance of deep drawing.<br />
