Nov 09 32 9 • Four high or cluster mills are used Al Cu alloys • Cold rolling cannot reduce the thickness of a workpiece as much as hot rolling in a single pass • This process increases strength upto 20 via strain hardeningThe roll gap is adjusted during the process resulting in a semifinished product with different thickness The process design of tailored rolled blanks implies new challenges and developments for rolling technology Rolling mills are forced to confront these challenges and to develop and apply new approaches in their engineering environment
