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。
The technical design, production process and technical parameters of 4V × 48S + 5FC-50 fan-shaped wire ropes are introduced. From the production of steel wire rope, electromagnetic wipe galvanized, polypropylene strands and rope selection and other aspects described in the production process, into a rope production using a specific type of pressure roller round extrusion. Given the basic parameters of wire rope: into a rope twisting multiples of 8.4, twisting 7.5 times. According to the twisting pitch of strands, the diameter of each layer of steel wire was determined. The diameter ratio of fiber core to wire rope was 0.32 and the tolerance of rope diameter was controlled from 0 to + 4%. Given the process of production into a rope and the round of the squeeze roll diagram and round extrusion process parameters. Trial production of 4V × 48S +5 FC-50 rope twisting effect is good, not loose, no stress, to non-rotating effect.
