Description

钢芯耐热铝合金绞线
技术领域
本发明涉及线缆技术领域，具体属于钢芯耐热铝合金绞线。
背景技术
随着我国电力需求的快速增长，电力能源在传输中的要求也越来越高。我国是多江河湖泊、多高山峡谷的国家，特别是西部的开发，将西北的水电、火电、西南的水电送往较为发达的中、东部地区，高压输电线路势必要经过各种跨越段区，特殊性能的大跨越大容量导电线的需求是必然的。然而目前，我国架空输电线路中所使用的导线基本上仍旧以传统的钢芯铝绞线为主，其耐热性能、耐腐蚀性能相对较弱，因此线路的输电容量、使用寿命受到一定的限制。
铝合金导线与钢芯铝绞线相比，有其不可比拟的优点，在大容量、长距离、大跨越、超高压输电中，独占优势；在农网、城网改造中，是既先进又经济的好产品，它是普通钢芯铝绞线的更新换代产品，也是节能、节材、节地( 节约输电走廊) 的产品。国际上五十年代开始采用至今，西欧、北欧、美国、加拿大、日本等国已广泛采用，法国的输电线路几乎90% 以上使用铝合金导线，日本达50% 以上，东南亚各国的使用量在逐年激增。
发明内容
本发明的目的是提供一种钢芯耐热铝合金绞线，导体采用耐热铝合金线，镀锌殷钢丝用于承受大部分的张力，铝合金线基本不承受张力，提高电阻率，该导线适用于高强度、大容量、大跨越输电线路，显著地提高输送容量和线路安全性。
本发明的技术方案如下：
一种钢芯耐热铝合金绞线，包括有以下工艺步骤：
1）制备线材，线材中各合金成分及重量百分比为：C0.09~0.11%，Si1.8~2.2%，Mn1.2~1.5%，P≤0.012%，S≤0.005%，Cr2.3~2.7%，W0.4~0.6%，V0.3~0.5%，Ni0.14~0.21%，Ti0.4~0.8%，Nb0.08~0.15%，Cu0.3~0.5%，Zr0.03~0.08%，余量为铝；
2）将线材进行预热，预热温度为340～400℃，预热时间为0.6～1.1min/mm，然后采用拉丝机对线材进行拉丝；
3）拉丝后进行淬火处理，淬火温度为250℃～300℃，淬火介质为三硝水溶液由15%硝酸钠、30%亚硝酸钠、28%硝酸钾、27%水组成；
4）淬火后进行碱洗、酸洗处理，碱洗采用65-80℃的氢氧化钠溶液，浓度为180-260g/L，酸洗采用常温盐酸，盐酸浓度为170-230g/L，含铁量≤120g/L。
线材中各合金成分及重量百分比为：C0.1%，Si1%，Mn1.35%，P0.01%，S0.003%，Cr2.5%，W0.5%，V0.5%，Ni0.17%，Ti0.6%，Nb0.11%，Cu0.4%，Zr0.05%，余量为铝。
本发明的优点是：钢芯铝合金导线长期工作温度210℃，是普通铝线长期工作温度的3 倍，导电率≥ 60%IACS，载流量是普通钢芯铝绞线的2 倍，提高了铝的利用率、节省了建设成本；2、钢芯铝合金导线的加强元件采用镀锌殷钢丝，其膨胀系数小，弛度减小；3、使用该钢芯铝合金导线可以减少占地面积，缓解了线路走廊紧张净空不足的问题。
