摘要

Process for vibration treating copper alloy melts comprises pouring a copper alloy melt into a casting mold anchored to a vibration table, and vibrating up to the end of the solidification. Preferred Features: The vibration table structured as a tilting table is oscillated using vibrators with a frequency of 20-100 Hz, an amplitude of less than 1 mm, an acceleration of 1-3 G (corresponding to 10-30 m/s2), and a horizontal or vertical oscillating direction.
