Abstract:

The report discusses the results of a program to find a method for removing internal stresses after reeling cylinders so that the dimension of the cylinder remained constant after removing the enveloping ring, which is used to protect the opening in the cylinder skirt against distortion during reeling. The ultrasonic method was selected since the work-hardened surface of the cylinder opening after reeling was thermodynamically unstable and ultrasonic vibrations always promote the transition of metal from a thermodynamically unstable state to a more stable one by removing internal stresses.
