面接触钢丝绳生产研究

介绍我国早期面接触钢丝绳的试制情况,以及几种面接触钢丝绳的生产方法:异型钢丝生产法;整体模拉拔法;辊式模拉拔法;轧制法;锻打法。研究几种压实股钢丝绳的生产方法及各自的特点:用模拉法生产时,模具孔型应选择直线型,定径带长度为模拉后股绳直径的0.13～0.20倍,工作锥角度为14°～16°;辊拉法和轧制法在孔型设计和工艺调整时,应考虑机架等压力系统的弹性伸长;锻打法的锻打速度与锻锤长度、锻打频率存在线性关系。介绍生产过程中钢丝绳产生翻棱的原因及解决办法,以及几种压实股弹性恢复率的测定方法。

Production research of surface contact wire rope

To introduce the trial-production of surface contact wire rope early in China, and the production methods of the rope are also introduced, that is：special shaped steel wire method, whole die drawing method, roller die drawing method, roiling method and swaged method. The production methods and their characteristics of several kinds of compacted strand wire rope are researched： die＇ s hole type should select straight line type as adopt die drawing method to produce, the sizing zone length is 0.13 -0.20 times strand rope diameter after drawing, working cone angle is 14° - 16°; roller die drawing and rolling method as hole type design and process adjusting, the elastic elongation of press system such as stander should be considered; the swaged speed and forging hammer length is linear relation to forging frequency as adopting swaged method. The cause for edge turning in wire rope production and the resolving method, the measure method of several kinds com- pacted strand elastic recovery rate are introduced.
