<p>A structural body and a method for cold rolling capable of continuously performing operations ranging from the rolling to the cutting of a deformed rolled material, the method comprising the step of providing a tension to the deformed rolled material passing through processes ranging from the rolling to a straightening, whereby a cost reduction and an energy saving can be achieved by eliminating the process annealing and the cleaning steps such as pickling and chemical conversion coating treatment of the deformed rolled material, a material loss can be suppressed to 5% or less, a dimensional variation of 0.05 mm or less, an increase in straightness of the material including the end parts after cutting, and a final accuracy of 0.1 mm can be provided, a lead time as a time required for processing can be remarkably shortened by in-line, and a running cost and a cost required for equipment can be reduced.</p> |
