Description

一种铝包钢绞线及生产方法
技术领域 本发明涉及电力线及制作方法。 背景技术 铝包钢导线， 按用途分为包钢芯铝绞线、铝包钢绞线及铝包钢芯 铝合金绞线。 在铝包钢坯杆制作过程中，坯杆中铝和钢的配比以及铝杆和钢丝 表面的洁净程度。铝和钢的配比直接影响到拉制后的铝包钢线中铝层 的厚度，进而影响到铝包钢的导电率。而铝杆和钢丝表面的洁净程度 可以影响铝在钢丝上的包覆效果。 现有的铝包钢绞线由载流量小、导体电阻大。现有的铝包钢绞线 生产工艺复杂， 成本高。 发明内容 本发明提供一种铝包钢绞线及生产方法，本发明解决了现有的铝 包钢绞线由载流量小、导体电阻大； 以及现有的铝包钢绞线生产工艺 复杂， 成本高的问题。 为解决上述问题， 本发明采用如下技术方案： 一种铝包钢绞线， 包括钢芯 2和铝包层 1, 钢芯 2是圆柱杆体结构， 在钢芯 2外面包 覆有铝包层 1。
一种铝包钢绞线的生产方法， 按照如下步骤操作- (一)制作钢线 按 GB/T 3428-2002采购钢线，根据铝包钢线的生产工艺提出技 术采购要求， 并进行钢丝放线、 钢丝校直、 钢丝清洗、 钢丝加热；
(二)制作铝杆 按 GB/T 3954-2008采购铝杆， 并提出满足设计生产的技术参 数； 并进行铝杆放线、 铝杆校直、 铝杆清洗；
(三)将铝线连续包覆于钢芯外面 坯杆制作，制作坯杆用铝杆和钢线严格按照试制工艺执行， 在生 产过程中必须保证铝杆和钢线清洗干净； 拉线， a)拉先用的坯杆必须按照试制工艺执行， 拉线过程必须保 证坯杆的干燥以及充分的润滑和冷却； b)拉线工艺和模具按试制工艺 执行； 成品绞制， a)绞线用的铝包钢线的必须检验合格方可使用； b) 绞线过程中严禁铝包钢线由刮伤、拉伤； 铝包钢线各盘张力必须均匀 一致； c)成品绞制的具体工艺按试制工艺执行；
(四）检验， 制成成品。 本发明的产品是由铝包钢丝绞合而成的铝包钢绞线，由于铝包钢 绞线在提高导线抗拉强度的同时增加了导线的导电截面，相对于钢绞 线而言， 铝包钢绞线由载流量大、 导体电阻小等优点， 提高了导线的 导线的导电性能。 本发明的生产方法具有工艺过程简单， 成本低的优点。 阱图说明 图 1是本发明侧面局部剖视图。 图中符号说明： 铝包层 1、 钢芯 2。
具体实施方式 下面用最佳的实施例对本发明做详细的说明。 如图 1所示， 一种铝包钢绞线， 包括钢芯 2和铝包层 1， 钢芯 2 是圆柱杆体结构， 在钢芯 2外面包覆有铝包层 1。
一种铝包钢绞线的生产方法， 按照如下步骤操作：
(一)制作钢线 按 GB/T 3428-2002采购钢线，根据铝包钢线的生产工艺提出技 术采购要求， 并迸行钢丝放线、 钢丝校直、 钢丝清洗、 钢丝加热；
(二)制作铝杆 按 GB/T 3954-2008采购铝杆， 并提出满足设计生产的技术参 数； 并进行铝杆放线、 铝杆校直、 铝杆清洗；
(三)将铝线连续包覆于钢芯外面 坯杆制作， 制作坯杆用铝杆和钢线严格按照试制工艺执行，在生 产过程中必须保证铝杆和钢线清洗干净； 拉线， a)拉先用的坯杆必须按照试制工艺执行， 拉线过程必须保 证坯杆的干燥以及充分的润滑和冷却； b)拉线工艺和模具按试制工艺 执行； 成品绞制， a)绞线用的铝包钢线的必须检验合格方可使用； b) 绞线过程中严禁铝包钢线由刮伤、拉伤； 铝包钢线各盘张力必须均勾 一致； C)成品绞制的具体工艺按试制工艺执行；
(四）检验， 制成成品。 本发明的生产工艺主要特点是注重清洗方面的工作， 保证无杂 物， 保证清洗剂的质量， 以及在操作过程中保持环境的卫生。在铝包 钢单线拉制过程中， 需要双金属同步拉伸工艺， 在拉伸过程中双金属 同步拉伸的控制是个难点。 最后应说明的是： 显然， 上述实施例仅仅是为清楚地说明本发明 所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人 员来说， 在上述说明的基础上还可以做出其它不同形式的变化或变 动。这里无需也无法对所有的实施方式予以穷举。而由此所引申出的 显而易见的变化或变动仍处于本发明的保护范围之中。
