我厂开展“振动时效”课题的试验研究和推广应用工作已有近十年的历史,现在本厂的大型焊接件和铸件床身已全部采用振动时效处理。生产应用表明,振动时效和热时效相比,具有以下优点;①生产率高。一个工件一般只需振动26～40分钟即可;②操作简便。由2～3人即可进行振动时效处理;?
I plant to carry out “vibration aging” pilot research and promotion of the work has been nearly 10 years of history, and now our large-scale welding parts and casting bed has been fully used vibration aging treatment. Production applications show that vibration aging and thermal aging compared with the following advantages; ① high productivity. A workpiece generally only vibration 26 to 40 minutes; ② easy to operate. By 2 to 3 people can be vibration aging treatment;
