Document Type and Number:
Japanese Patent JP4332117
Kind Code:
B2
Abstract:
An aluminum ingot is subjected to hot rolling, cold rolling and then intermediate annealing to obtain a rolled article. Tensile strain is applied to the rolled article without subjecting the rolled article to cold rolling after the intermediate annealing but before initiation of final annealing, and thereafter the rolled article is subjected final annealing. An application of the tensile strain is performed using a tensile strain application equipment 1 having two or more bridle roll units 10 and 11 disposed in a transferring direction of the aluminum material S for forming a tension applying area Q between adjacent bridle roll units 10 and 11 in such a manner that between a peripheral speed Pi of an upstream-side bridle roll unit and a peripheral speed Po of a downstream-side bridle roll a peripheral speed difference of Pi
