1. The cold rolled steel strip intended for pressing will avoid "slide line" during pressing if having been straightened at small press-down ratio in advance. The stress-strain curve of steel that has been straightened at some press-down ratio will avoid yield plateau.2. The rolled steel strip that was straightened after having been annealed will generate a better straightness and improved smoothness on the surface.3. Once the press-down ratio of pinch passing is adjusted, the steel strips mechanical performance will be changed as a fixed ranged, enabling its rigidity and flexibility to meet with different uses of tinning strips.
