60年代中,日本首次试制了股绳捻距小而钢绳捻距大的四股扇形或三角形钢丝绳,称为MonoRope。到70年代初,日本东京制钢、神钢、兴国、帝国等钢丝绳厂大力推广四股钢丝绳。目前除了日本以外,西欧各国均未开发此种成形加工的四股钢丝绳。近年来我国交通部进口不少四股钢丝绳,发现钢绳加工成形后,外层钢丝有大量伤痕。为此,对四股钢丝绳的制造及性能进行了分析。 In the 1960s, for the first time in Japan, four fan-shaped or triangular wire ropes of small strand lay lengths and large lay lengths of steel ropes were made, known as MonoRope. By the early 1970s, Japan Tokyo Steel, Kobelco, Xingguo, Empire and other wire rope plant vigorously promote the four shares of wire rope. At present, except for Japan, none of the Western European countries have developed such four-strand wire rope for forming and processing. In recent years, China’s Ministry of Transportation imported a lot of four wire ropes, steel wire rope forming processing, the outer wire has a lot of scars. To this end, the four strands of rope manufacturing and performance were analyzed.
