  • 产品详情
  • 6×K31WS-FC 是一款 6 股 K 型压实瓦林吞 - 西鲁式股 + 纤维芯 的中重型柔韧性钢丝绳,兼具高承载潜力、优异弯曲灵活性与轻量化特性,符合 GB/T 8918-2016《重要用途钢丝绳》标准,适用于中型履带吊副钩、港口轻型卸船机、建筑大型塔吊变幅机构、风电塔筒分段吊装辅助绳等对中重载、频繁大角度弯曲、便捷运维有需求的作业工况。

    型号含义拆解

    型号部分含义说明
    6外层为 6 个工作股,对称排列设计配合交叉捻向结构,相比 8 股型号单股截面更大、承载效率更高,可有效抵消中重载吊装时的扭转扭矩,实现低旋转特性,避免货物摆动、吊钩打转
    ×K31WSK 型压实瓦林吞 - 西鲁式股(WS=Warrington-Seale 复合结构),每股由 31 根粗细交替钢丝排布而成,经冷压实工艺处理后股径缩小、钢丝呈面接触状态,金属截面积利用率大幅提升,抗疲劳、抗磨损性能远超普通捻制股
    -FC纤维芯(Fiber Core),材质多为聚丙烯或剑麻,相比独立钢绳芯(IWRC)重量更轻、柔韧性更好,适配中型卷筒的频繁大角度弯曲作业,降低设备传动系统负载损耗

    一、基础结构参数

    参数项详细说明
    结构组成6 个 K 型压实瓦西式外层股 + 纤维芯(FC,聚丙烯 / 剑麻材质);外层股与绳芯采用交叉捻向(外层右捻、芯左捻),绳体圆整度高,旋转扭矩低,柔韧性优于同规格 6×K31WS-IWRC 型号
    钢丝材质优质高碳钢(#82B、#925),经冷拔强化 + 股压实处理;外层股钢丝表面可选热镀锌 / 电镀锌 / 光面,按需匹配防腐与耐磨需求
    表面处理1.  热镀锌:镀层厚 30~60μm,适用于沿海高盐雾、矿山潮湿等中强腐蚀中重载场景
    2.  电镀锌:镀层厚 8~15μm,适用于干燥室内中重型起重工况
    3.  光面:无镀层,需定期加注专用润滑脂,适用于无尘高精度吊装场景
    直径范围常见 16~60mm,主流应用 24~54mm 中重型提升 / 牵引场景
    公称抗拉强度高碳钢型:1770MPa、1960MPa、2160MPa(中重型吊装设备优先选用 1960MPa 等级,兼顾强度与柔韧度)
    重量系数0.400~0.430(比同规格 6×K31WS-IWRC 轻 23%~27%,轻量化优势显著)
    最小破断拉力系数0.300~0.320(K 型压实工艺提升金属利用率,比普通 6×31WS+FC 系列提升 15%~20%,满足中重载作业强度需求)

    二、典型力学性能表(1960MPa 热镀锌 + 聚丙烯纤维芯)

    公称直径(mm)参考重量(kg/100m)最小破断拉力(kN)适用场景
    243801750中型塔吊变幅绳、港口门式起重机辅助起升绳
    347203400中型履带吊副钩绳、港口轻型卸船机主绳
    4411805400建筑大型塔吊辅助起升绳、风电塔筒分段吊装辅助绳
    5417807900中型港口件杂货起重机主绳、重型预制件短途转运绳
    注:若选用剑麻纤维芯,耐温性(≤120℃)优于聚丙烯芯,但耐水性较差,重量略增 3%~5%;热镀锌处理对破断拉力的影响小于 2%。

    三、核心特性

    1. 中重载高柔韧性,适配频繁大角度弯曲
      6 股大截面结构保障中重载承载能力,纤维芯的弹性缓冲作用让绳体弯曲半径比同规格钢芯型号小 25%~30%,能适配中型卷筒的高频次起升下放、大角度换向作业,尤其适合塔吊变幅、履带吊副钩等需要频繁调整吊装角度的场景。
    2. 轻量化设计,降低设备负载损耗
      纤维芯替代钢绳芯,整体重量大幅降低,减少中重型起重设备的整机负载与能耗,同时降低人工搬运、安装的难度,延长设备传动系统与卷筒的使用寿命,适配需要频繁转场的中型吊装设备。
    3. 耐磨耐疲劳,使用寿命长
      瓦林吞 - 西鲁式股的外层粗钢丝与滑轮、卷筒接触面积均匀,磨损速率低;压实工艺让股内 31 根钢丝紧密贴合,减少微动摩擦损耗,耐疲劳性能是普通 6×31WS+FC 钢丝绳的 1.7~2.1 倍,降低设备运维成本。
    4. 防腐性能可控,适配多环境作业
      热镀锌镀层附着力强,可抵御沿海盐雾、矿山潮湿等腐蚀环境;搭配纤维芯专用防腐润滑脂,既能润滑钢丝接触面,又能防止纤维芯受潮腐烂,维护周期可延长至普通纤维芯钢丝绳的 1.5 倍。

    四、选型与使用要点

    1. 安全系数选择
      • 中型履带吊副钩 / 建筑大型塔吊变幅:7~9 倍
      • 港口轻型卸船机 / 风电塔筒分段吊装:9~11 倍
      • 严禁用于矿山竖井提升、超重型设备长期悬挂、高温(>120℃)等重载高危工况
    2. 纤维芯选型建议
      • 户外潮湿 / 沿海腐蚀环境 → 聚丙烯纤维芯(耐水耐腐蚀,性价比高)
      • 钢厂附近等高温作业场景 → 剑麻纤维芯(耐温性好,需做好防水防护)
      • 高精度无尘吊装场景 → 改性聚丙烯纤维芯(低粉尘脱落,清洁度高)
    3. 卷筒与滑轮匹配
      • 卷筒直径 ≥ 钢丝绳直径的 19~24 倍
      • 滑轮直径 ≥ 钢丝绳直径的 17~21 倍
      • 滑轮槽底需为圆弧浅槽精密加工,与绳径精准匹配,避免股丝受力不均引发断丝
    4. 维护注意事项
      • 定期加注 纤维芯钢丝绳专用防腐润滑脂,采用低压注脂方式,确保润滑脂渗透至股间缝隙,不可使用钢绳芯专用润滑脂(易堵塞纤维芯孔隙)
      • 检查重点为 股端断丝、绳径磨损、纤维芯外露、镀层脱落,出现单股 2 丝断丝或纤维芯外露时需立即报废
      • 运输与存放时需使用专用中型支架盘卷,避免挤压变形、尖锐物划伤镀层;长期存放置于干燥通风环境,每 3 个月翻动一次,防止局部锈蚀

常见问题

阐述什么样的润滑剂可以防止钢丝绳损害?


一、光滑油具有良好的流动性和浸透能力,在钢丝绳进行光滑预处理时就能敏捷进入绳子内部以及绳芯,并能起到避免细菌在绳芯纤维内部繁殖的作用。

二、光滑油粘附在钢丝绳上不会轻易被擦掉,在规定的温度变化范围内光滑作用也不会受到影响。此外,具有粘附功能的光滑油还能防滑,这对电梯用钢丝绳附着摩擦力供给了协助。

三、有着较高的油膜强度,能在极重载荷下抵抗彼此接触的钢丝之间存在的极高压力,还能抗分解、蜕变。

四、光滑油油脂具有较高的内聚力,可以避免光滑油的滴落,没有运动时离心甩失,避免油脂糟蹋以及对其他设备的污染。

五、不含有会引起钢丝绳产生腐蚀、生锈的成分,防腐蚀、防锈蚀的作用更佳。

六、其自我修正的能力强,钢丝绳运用时不断产生曲折,会使其表面油膜不断揉捏扩张。这就需求柔软的并且有较高温润性的油膜来维护绳体免于开裂。
