Detailed Product Description

 Its unique functions are as follows:1. The cold rolled steel strip used for punching might not have slip line through the dressing of small cog down. After dressed by a certain extent of cog down rate, the stress curve of steel may not have yield step.
2. After annealing, the cold rolled steel strip can improve the flatness (profile shape) of steel strip and roughness of steel strip surface through being dressed.
3. Adjust the cog down rate of dressing, which can not only make the mechanical property of steel strip be changeable in a stated range but also make the hardness of steel strip and plasticity applicable for different functional tinning strip.
