  • 产品详情
  • 6×K31WS-IWRC 是一款 6 股 K 型压实瓦林吞 - 西鲁式股 + 独立钢丝绳芯 的中高强度重型压实钢丝绳,符合 GB/T 8918-2016《重要用途钢丝绳》标准,适用于中型履带吊主钩、港口件杂货起重机、矿用提升设备、建筑大型塔吊起升机构等对高承载、抗挤压、多层缠绕有严格要求的作业工况。

    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 股型号刚性更强、单股载荷分配更均匀,能有效抵消重载时的扭转扭矩,实现低旋转特性,避免重型吊装时吊钩打转、货物摆动
    ×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
    -IWRC独立钢丝绳芯(Independent Wire Rope Core),常规为 7×19 或 7×37 结构,由独立钢绳捻制而成,提供极强的径向支撑力与抗挤压能力,适配中型及大型卷筒的多层缠绕工况,承载稳定性远超纤维芯(FC)型号

    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 + 独立钢丝绳芯(IWRC);外层股与绳芯采用交叉捻向(外层右捻、芯左捻),绳体圆整致密,旋转扭矩低,抗挤压性能优于同规格 6×K31WS-FC 型号
    钢丝材质优质高碳钢(#82B、#925),经冷拔强化 + 股压实处理;外层股与绳芯钢丝表面可选热镀锌 / 电镀锌 / 光面,按需匹配不同腐蚀工况
    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重载场景
    2.  电镀锌:镀层厚 8~15μm,适用于干燥室内重型起重工况
    3.  光面:无镀层,需定期加注专用润滑脂,适用于无尘高精度重型吊装场景
    直径范围常见 18~65mm,主流应用 26~58mm 重型提升 / 牵引场景
    公称抗拉强度高碳钢型:1770MPa、1960MPa、2160MPa(重型重载设备优先选用 1960MPa 等级,兼顾强度与耐疲劳性)
    重量系数0.540~0.570(比同规格 6×K31WS-FC 重 22%~26%,比 6×K36WS-IWRC 轻 5%~8%)
    最小破断拉力系数0.390~0.410(K 型压实工艺 + IWRC 绳芯协同作用,金属利用率比普通 6×31WS+FC 系列提升 18%~23%)

    二、典型力学性能表(1960MPa 热镀锌 + IWRC 芯)

    公称直径(mm)参考重量(kg/100m)最小破断拉力(kN)适用场景
    265202450中型塔式起重机主起升绳、港口门式起重机牵引绳
    369804600中型履带吊主钩绳、矿用提升设备主绳
    4615807300港口件杂货起重机主绳、建筑大型塔吊主绳
    56232010700中型港口卸船机主绳、重型预制件吊装绳
    注:热镀锌处理对破断拉力的影响小于 2%;IWRC 绳芯的高刚性支撑特性,可减少大型卷筒多层缠绕时的股间变形,延长钢丝绳使用寿命。

    三、核心特性

    1. 高承载抗挤压,适配多层缠绕工况
      6 股大截面结构 + K 型压实工艺,结合 IWRC 独立钢芯的强径向支撑,能承受中型履带吊、矿用提升设备的多层缠绕挤压应力,股间变形量比纤维芯型号减少 30%~35%,适配高频次起升下放作业。
    2. 低旋转高稳定,保障重型精准吊装
      6 股对称排列 + 交叉捻向设计,有效抵消重载吊装时的扭转扭矩,吊钩旋转幅度控制在极小范围,避免重型货物摆动引发的安全隐患,满足建筑塔吊、港口件杂货吊装的高精度作业需求。
    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 2.0~2.4 倍,降低设备运维成本。
    4. 高刚性适配大载荷,结构稳定性强
      相比 8 股同规格型号,6 股结构的刚性更强,在大载荷下的形变更小,能长期保持稳定的承载性能,适配需要持续承受高负荷的中型重型起重设备。

    四、选型与使用要点

    1. 安全系数选择
      • 中型塔吊主起升 / 港口门式起重机:6~8 倍
      • 中型履带吊主钩 / 矿用提升设备:7~9 倍
      • 港口件杂货起重机 / 重型预制件吊装:8~10 倍
      • 严禁用于强酸碱腐蚀无防护、超高温(>200℃)等极端工况
    2. 环境适配原则
      • 干燥室内重型起重 → 电镀锌全绳型号
      • 户外 / 矿山 / 沿海中强腐蚀环境 → 热镀锌型号,定期加注防腐润滑脂
      • 强腐蚀环境 → 搭配聚氨酯(PU)护套,隔绝腐蚀介质
    3. 卷筒与滑轮匹配
      • 卷筒直径 ≥ 钢丝绳直径的 27~32 倍
      • 滑轮直径 ≥ 钢丝绳直径的 24~29 倍
      • 滑轮槽底需为圆弧深槽精密加工,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 钢绳芯专用防腐润滑脂,采用高压注脂设备,确保润滑脂渗透至股间和绳芯缝隙,不可使用纤维芯专用润滑脂
      • 检查重点为 股端断丝、绳径磨损、镀层脱落、股间松动,出现单股 3 丝断丝时需立即报废
      • 运输与存放时需使用专用大型支架盘卷,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,定期检查防锈情况

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。
