小规格多层股钢丝绳的生产

Production of Small Specifications Multiple Layer Strand Wire Rope

以 34× 7+IWS— 12mm、 14mm为例介绍多层股不旋转钢丝绳的生产经验。除了调预变形器的边辊距、压弯值之外 ,生产时还要使内层绳不预变形 ,内、中层绳制成半松散状态以增大弹性 ,外层绳不松散以减小弹性 ,使内外扭转力矩平衡 ,以达到不旋转的目的。操作时先将内层绳拉出上劲 ,再引头生产。通过这些措施使小规格多股钢绳的质量大大提高 。

To introduce the production experience of non rotation multiple layer strand wire rope taking 34×7+IWS? I 12?mm and 14?mm for example The aim of non rotation can be got through making inner moment of torsion be in equilibrium with external by adjusting the edge roller gap and bend value of pre deformation apparatus,making inner rope not predeform,making inner middle layer rope into half loose state so as to increase elasticity,making external layer strands be not loose so as to decrease elasticity Inner layer rope is drawn out to be wound at first,and then the whole rope head is drawn forth to produce After taking these measures the quality of the small specifications multiple layer strand wire rope is risen greatly,and the rope can satisfy the needs of domestic and overseas consumers
