ABSTRACT:
A billet is initially rolled into a process section having at least first and second segments joined by an intermediate web, with the cross-sectional area of the second segment being larger than that of the first segment. The intermediate web is slit to separate the first and second segments, and the thus separated segments are simultaneously rolled into finished products having different cross-sectional areas.
