超声波技术应用于冷拔钢管或其他金属塑性加工是近年来功率超声应用的新发展,是一项新技术。这种技术能提高产品质量及经济效益,因此,世界各国都在进行研究、实验和积极开发。早在60年代初,美国宾州的Uniforn Tubes公司首次安装了超声拉管装置的样机。经过不断的研 Ultrasonic technology used in cold drawn steel pipe or other metal plastic processing is the new development of power ultrasonic applications in recent years, is a new technology. This technology can improve product quality and economic benefits, therefore, all countries in the world are studying, experimenting and actively developing. As early as the early 1960s, the Uniforn Tubes Company in Pennsylvania, the United States, installed a prototype of an ultrasonic catheterization device for the first time. After continuous research
