4V×48S+5FC—50镀锌扇形股钢丝绳研制

介绍4V×48S+5FC—50扇形股钢丝绳的工艺设计、生产过程和技术参数修订。从制绳钢丝生产、电磁抹拭镀锌、聚丙烯股和绳芯的选用等方面叙述生产流程,成绳生产采用特定孔型的压辊对圆股进行挤压成型。给出钢丝绳基本参数:成绳捻距倍数8.4,股绳捻距倍数7.5。根据股绳捻距倍数来确定各层钢丝的直径,纤维芯与钢丝绳直径比为0.32,绳径公差控制在0～+4%。给出成绳生产的工艺流程及圆股挤压辊图和圆股挤压的工艺参数。试制出的4V×48S+5FC—50钢丝绳捻制效果良好,不松散,无应力,达到不旋转的效果。

Development of 4V × 48S +5FC-50 galvanized fan strands wire rope

To introduce the process design,production process,and technical parameter revising of 4V×48S+5FC—50 fan strands wire rope.Production flow is introduced from steel wire for rope production,electromagnetic wiping galvanized,the selection of polypropylene strand and rope core,wire rope production adopts press roller of special hole pattern to extrusion form on round strands.Wire rope basic parameters are given as follows:wire rope lay pitch multiple is 8.4,stranded rope lay pitch multiple is 7.5.The diameter of each layer steel wire is determined according to stranded rope lay pitch multiple,the diameter ratio of fiber core to wire rope is 0.32,rope diameter tolerance is controlled 0～+4%.The process flow of wire rope production and round strands extrusion roller diagram and round strands process parameters are given.4V×48S+5FC—50 wire rope of trail production laying effect is good,no looseness,unstressed,reaches the effect of non-rotating.
