6×19W+IWRC

一家专业从事钢丝绳的生产、研发、销售的公司,开发并生产为电梯绳生产企业做配套服务,重点为 6*19 的钢丝绳,同时兼做部分出口业务,以热镀锌钢丝绳为主
  • 产品详情
  • 6×19W+IWRC 是 6 股 ×19 丝(瓦林吞式结构)+ 独立钢绳芯 的线接触钢丝绳,结构紧凑、耐磨抗冲击,属于工业通用型中重载规格,符合 GB/T 20118-2017《钢丝绳通用技术条件》,适用于起重机械、建筑卷扬、港口装卸、矿山斜井提升等对耐磨性和承载稳定性要求较高的工况。

    型号含义拆解

    • 6:钢丝绳由 6 个外层股 组成
    • 19W:每个外层股包含 19 根钢丝,采用瓦林吞式(Warrington)排列,股内为两种不同直径钢丝交替分布,外层粗钢丝提升耐磨性,内层细钢丝填补间隙,实现线接触受力
    • IWRC:绳芯为独立钢绳芯(常规为 7×7 结构),区别于纤维芯(FC),可增强绳体的抗挤压性与承载能力

    一、基础结构参数

    参数项详细说明
    结构组成6 个瓦林吞式外层股 + 独立钢绳芯(IWRC);每股 19 丝为 “粗 - 细 - 粗” 交替排布,线接触设计降低股内钢丝接触应力,结构密实度高
    钢丝材质优质碳素结构钢(#60、#70、#72A),冷拔强化处理;高端型号可选热镀锌钢丝、合金钢丝,提升耐腐蚀性与抗磨损性能
    表面处理1. 光面:无镀层,适用于干燥无尘的室内重载工况
    2. 热镀锌:厚镀层(30~60μm),强耐腐蚀,适用于户外 / 沿海 / 矿山腐蚀环境
    3. 电镀锌:薄镀层(8~15μm),装饰性防锈,轻度潮湿环境可用
    直径范围常见 10~56mm,主流应用 16~40mm 中重载提升场景
    公称抗拉强度碳钢型:1570MPa、1670MPa、1770MPa、1960MPa(工业常用 1770MPa 等级)
    捻向右同向捻(RHRL)、左同向捻(LHLL)、右交互捻(RHRH);6 股结构抗旋转性弱于 8 股绳,需搭配导向滑轮使用
    重量系数0.390~0.405(IWRC 芯参考值;热镀锌后重量增加 3%~5%)
    最小破断拉力系数0.340~0.350(瓦林吞式股金属截面积利用率高于点接触 6×19 钢丝绳,略低于瓦 - 西混合结构)

    二、典型力学性能表

    1. 碳钢型(1770MPa,光面)

    公称直径(mm)参考重量(kg/100m)最小破断拉力(kN)适用场景
    1676112小型起重机主钩、建筑卷扬机
    20118178中型起重机副钩、港口龙门吊辅助钩
    28232348塔吊主钩、矿山斜井提升
    36388585大型履带吊副钩、风电塔筒辅助吊装
    40472708港口卸船机、盾构机配套牵引

    2. 碳钢型(1770MPa,热镀锌)

    公称直径(mm)参考重量(kg/100m)最小破断拉力(kN)适用场景
    20124174户外建筑卷扬机、潮湿环境吊装
    28240340沿海港口装卸、矿山腐蚀环境运输
    36400572海上平台轻型牵引、化工园区物料吊装
    注:热镀锌处理后破断拉力比光面低 1%~2%;抗拉强度提升至 1960MPa 时,破断拉力约增加 11%~13%。

    三、核心特性

    1. 耐磨性优异
      股外层粗钢丝与卷筒、滑轮接触时磨损速率低,在粉尘、砂石等恶劣工况下,使用寿命比普通点接触 6×19 钢丝绳长 15%~25%,适配矿山、港口等场景。
    2. 抗冲击与抗挤压能力强
      IWRC 钢绳芯提供强力支撑,搭配瓦林吞式股的弹性缓冲,在冲击载荷下不易出现断丝、鼓包;径向抗挤压性能好,多层缠绕卷筒时绳体不易变形。
    3. 柔韧性与承载均衡
      纯瓦林吞式股的柔韧性优于瓦 - 西混合结构,可适配中等直径卷筒,满足频繁起升下放的作业需求;同时线接触设计保证受力均匀,承载能力满足中重载设备要求。
    4. 通用性强,性价比高
      属于国标经典规格,配套的卷筒、滑轮、卡扣等配件成熟易采购,生产成本低于瓦 - 西混合结构钢丝绳,是中重载工况的高性价比选择。

    四、选型与使用要点

    1. 安全系数选择
      • 中型起重 / 建筑吊装:5~6 倍
      • 矿山运输 / 港口装卸:6~7 倍
      • 严禁用于载人设备及无导向滑轮的单侧长距离牵引
    2. 环境适配原则
      • 干燥室内重载 → 光面碳钢绳
      • 普通户外 / 矿山 → 热镀锌碳钢绳
      • 沿海 / 酸碱腐蚀环境 → 合金钢丝热镀锌型号
    3. 卷筒与滑轮匹配
      • 卷筒直径 ≥ 钢丝绳直径的 18~22 倍
      • 滑轮直径 ≥ 钢丝绳直径的 16~20 倍
      • 滑轮槽底半径需与绳径匹配,防止局部应力集中导致断丝
    4. 维护注意事项
      • 定期加注钢丝绳专用润滑脂,润滑钢丝同时保护 IWRC 芯免受锈蚀
      • 检查时重点关注股间断丝、绳径磨损,单股出现 3 丝以上断丝需立即报废
      • 避免钢丝绳与尖锐物体碰撞,防止股结构损伤

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。
