Abstract:
The application of 10 to 20 kc acoustic energy during the rolling of metal sheet was investigated. The considerable theoretical potential of both the volume and surface contributions of ultrasound to rolling is described, particularly with respect to sheet thickness. The importance of the relative directions of vibrational displacement, deformation force and metal flow is pointed out. A series of rolling experiments in which a magnetostrictive transducer was attached to the workpiece is described, and load reductions on the order of 5 attained during these experiments related to the acoustic parameters. A roll design incorporating an ultrasonic transducer in the interior of the roll was formulated and constructed. The extensive electromechanical problems encountered during roll construction are described. These problems were only partially solved and the resultant rolls had a very short life, although load reductions of 5 were obtained on several materials. Author
