  • 产品详情
  • 6×K7-FC 是一款 6 股 K 型压实点接触式股 + 纤维芯 的微型轻型钢丝绳,符合 GB/T 8918-2016《重要用途钢丝绳》标准,适用于手动葫芦、微型卷扬机、小型门窗升降机构、精密仪器牵引等对极轻载、超高柔韧性、便携操作有需求的作业工况。

    型号含义拆解

    型号部分含义说明
    6外层为6 个工作股,对称排列配合交叉捻向结构,单股截面小巧、载荷分布均匀,能有效抵消极轻载工况下的扭转扭矩,实现低旋转特性,避免小型精密部件摆动、移位
    ×K7K 型压实点接触式股,每股由 7 根粗细均匀的钢丝捻制而成,经冷压实工艺处理后股径缩小、钢丝间隙减小,提升结构紧凑性与耐磨性,抗疲劳性能优于普通非压实 6×7 钢丝绳
    -FC纤维芯(Fiber Core),材质多为聚丙烯或尼龙纤维,相比独立钢丝绳芯(IWRC)重量更轻、柔韧性极佳,适配微型卷筒的极小半径弯曲作业,降低手动操作的阻力

    一、基础结构参数

    参数项详细说明
    结构组成6 个 K 型压实点接触式外层股 + 纤维芯(FC,聚丙烯 / 尼龙材质);外层股与绳芯采用交叉捻向(外层右捻、芯左捻),绳体柔软易弯折,旋转扭矩极低,柔韧性远优于同规格钢芯型号
    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,按需匹配防腐与耐磨需求
    表面处理1.  热镀锌:镀层厚 20~40μm,适用于潮湿环境下的微型牵引、升降作业
    2.  电镀锌:镀层厚 5~10μm,适用于干燥室内精密仪器、小型设备的牵引工况
    3.  光面:无镀层,需定期涂抹防锈油,适用于无尘环境下的临时捆绑、牵引
    直径范围常见 3~12mm,主流应用 4~8mm 微型提升 / 牵引场景
    公称抗拉强度高碳钢型:1770MPa、1960MPa、2160MPa(微型设备优先选用 1770MPa 等级,兼顾柔韧性与强度)
    重量系数0.320~0.350(轻量化优势突出,比同规格 6×K7-IWRC 轻 35%~40%)
    最小破断拉力系数0.200~0.220(K 型压实工艺提升金属利用率,比普通 6×7+FC 系列提升 10%~15%,满足极轻载作业强度需求)

    二、典型力学性能表(1770MPa 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
    45.20.85小型门窗升降绳、精密仪器内部牵引绳
    611.71.90手动葫芦提升绳、微型卷扬机牵引绳
    820.83.30小型货架货物吊装绳、轻型设备临时捆绑绳
    注:尼龙纤维芯的柔韧性优于聚丙烯芯,但耐候性稍差,适用于室内无尘环境;热镀锌处理对破断拉力的影响小于 2%。

    三、核心特性

    1. 极轻载高柔韧性,适配极小半径弯曲
      6 股细股结构 + 纤维芯弹性缓冲,绳体可实现极小半径弯折(弯曲半径可低至钢丝绳直径的 5~8 倍),适配微型卷筒、狭小空间内的牵引与升降作业,操作灵活无卡顿。
    2. 超轻量化设计,降低手动操作强度
      纤维芯替代钢芯大幅减轻绳体重量,搭配细直径钢丝结构,手动提拉时阻力小,尤其适合手动葫芦、微型卷扬机等人力驱动设备,提升操作便捷性。
    3. 耐磨防锈,适配多场景微型作业
      冷压实工艺减少钢丝间的微动摩擦,提升耐磨性;热镀锌镀层可抵御潮湿环境的锈蚀,延长使用寿命;电镀锌型号表面光滑,避免划伤精密仪器表面。
    4. 低维护成本,适配简易作业场景
      纤维芯无需复杂润滑维护,仅需定期擦拭防锈,相比钢芯钢丝绳减少润滑脂加注步骤,降低微型设备的运维难度。

    四、选型与使用要点

    1. 安全系数选择
      • 手动葫芦 / 微型卷扬机:8~10 倍
      • 精密仪器牵引 / 门窗升降:10~12 倍
      • 严禁用于重载吊装、强酸碱腐蚀、高温(>100℃)等极端工况
    2. 纤维芯选型建议
      • 户外潮湿环境 → 聚丙烯纤维芯(耐候性好、防水防潮)
      • 室内精密仪器 → 尼龙纤维芯(柔韧性佳、表面光滑)
      • 临时捆绑作业 → 普通聚丙烯纤维芯(性价比高)
    3. 卷筒与滑轮匹配
      • 卷筒直径 ≥ 钢丝绳直径的 10~15 倍
      • 滑轮直径 ≥ 钢丝绳直径的 8~12 倍
      • 滑轮槽底需为圆弧浅槽精密加工,槽宽与绳径匹配,避免卡绳、断丝
    4. 维护注意事项
      • 定期用干布擦拭绳体表面灰尘,潮湿环境下可涂抹少量防锈油
      • 检查重点为 股端断丝、绳体磨损、镀层脱落,出现单根断丝或局部磨损量超过钢丝直径的 1/3 时需立即报废
      • 运输与存放时需盘卷整齐,避免挤压变形;长期存放需置于干燥通风环境,远离酸碱、高温源

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。
