点接触圆股钢丝绳的特点与优质捻制

介绍圆股点接触钢丝绳的结构特点及缺陷。点接触钢丝绳应用范围缩小、数量减少,将部分或者全面退出重要用途领域,是国内外钢丝绳行业发展的必然趋势,但仍然有可开发利用之处,在载货、捆绑吊索、江海打捞等领域内点接触钢丝绳依然在用。为全面提高钢丝绳使用性能与寿命,应重新认识点接触钢丝绳,重点阐明点接触钢丝绳的基础功能以及优质捻制点接触钢丝绳的必要性。以捻制6×37+FC—17.5点接触钢丝绳为例,介绍凸丝捻制缺陷的内涵、危害及产生的原因,以及国内钢丝绳企业进行优质捻制的观点与具体措施。

Characteristic and excellent spinning of point contact lay round strand wire rope

To introduce the characteristic and structure defect of round strand point contact lay steel wire rope,whose application range and number is reducing and will withdraw partly or totally in some important field,while it still has advantages on loading goods,binding sling and salvage.In order to enhance its service performance and life,the point contract lay steel wire rope should be reacquainted and its basic foundation and the necessity of excellent spinning point contact lay steel wire should be emphasized.Taking 6×37＋FC—17.5＇s spinning as an example to introduce the content,disadvantage,caused reason of wire bulging spinning defect,and the view and measure of domestic steel wire rope enterprises＇ excellent spinning.
