前言超声波应用于金属丝材拉拔工艺,已发挥了独特的作用,获得了明显的技术经济效果,是拉丝工艺的重要革新。因此已为各国冶金工程师们和声学研究者们所重视。我们对超声波单模拉丝已作了比较系统的工艺试验,并取得了可喜的效果。但对于中丝和细丝拉拔,则要求采用多模拉丝机,其理由是众所周知的。超声波多模拉丝的研究主要分成二部 Foreword Ultrasonic applied to the wire drawing process, has played a unique role, access to a significant technical and economic results, is an important innovation in the drawing process. Therefore, the metallurgical engineers of all countries and acoustic researchers have valued. We have made a comparatively systematic technological experiment on the ultrasonic single-mode drawing and achieved gratifying results. However, the drawing of filaments and filaments requires the use of a multi-die drawing machine, the reason for which is well-known. The research of ultrasonic multi-mode drawing is mainly divided into two parts
