一、前言在毛主席革命路线的指引下,我国的仪表工业取得了很大的进展。仪表工业所需的微细丝材的种类与日俱增,因此研究和发展生产细丝的工艺是十分必要的。近年来,除了对惯用的模拉法不断改进以外,还发展了许多新的工艺,如电镀拉丝法、无模拉伸法、玻璃绝缘层法、蒸发光刻法、化学腐蚀法、电化学减径法、电沉积拉丝法、一次挤压法等。 I. Foreword Under the guidance of Chairman Mao’s revolutionary line, great progress has been made in China’s instrument industry. As the types of fine wires required by the instrumentation industry are increasing, it is imperative to study and develop the process of producing filaments. In recent years, in addition to the continuous improvement of the conventional mold-drawing method, many new processes have been developed, such as electroplating drawing method, die-free drawing method, glass insulating layer method, evaporative photolithography, chemical etching, electrochemical reduction Diameter method, electrodeposition drawing method, a squeeze method.
