Detailed Product Description

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