扇形股钢丝绳具有破断拉力高、耐磨性好、耐挤压、不旋转、耐疲劳、使用寿命长等特点。介绍一种采用特殊的预变形卡具加圆股挤压法生产4V×39S+5FC—32扇形股镀锌钢丝绳的方法,选择70钢盘条作为拉拔制绳钢丝的原料,给出钢丝绳的工艺参数及制绳钢丝拉拔工艺,镀锌采用电磁抹拭技术。股绳捻制第1层的股捻距为52.6 mm,第2层的捻距为102 mm。合绳在筐篮式8/1250成绳机上生产,圆股挤压采用“4×4”形式,给出圆股挤压工艺参数和装置参数。生产出的钢丝绳不松散、无应力,满足客户需求。
Fan-shaped wire rope with high breaking strength, wear resistance, resistance to extrusion, no rotation, fatigue resistance, long service life and so on. This paper introduces a method of producing 4V × 39S + 5FC-32 fan-shaped galvanized steel wire rope by using special pre-deforming clamp plus round extrusion method, selecting 70 steel wire rod as the raw material of drawing ropes steel wire, Process parameters and rope drawing process, galvanized using electromagnetic wiping technology. The twisting pitch of the first layer of strand is 52.6 mm, and the twisting pitch of the second layer is 102 mm. Co-rope in the basket basket 8/1250 into rope machine, the round extrusion of “4 × 4 ” form, given the round extrusion process parameters and device parameters. Produced rope is not loose, no stress, to meet customer needs.
