摘要:

輸電桿塔是輸電線路工程中重要的基礎(chǔ)設(shè)施。長(zhǎng)期以來, 鋼基桿塔主要采用熱浸鍍鋅工藝來進(jìn)行防腐, 但間歇式熱浸鍍鋅工藝具有污染環(huán)境、能源消耗大、成本高等特點(diǎn), 且熱鍍鋅桿塔使用后期需進(jìn)行維護(hù)。因此, 亟需尋找新型防腐材料替代熱鍍鋅鋼。在大氣環(huán)境中, 耐候鋼表面會(huì)形成致密且粘附良好的穩(wěn)定銹層, 具有比普碳鋼更好的耐蝕性能, 將耐候鋼應(yīng)用于輸電桿塔是輸電桿塔防腐蝕技術(shù)未來的重要發(fā)展方向之一。使用耐候鋼制造輸電桿塔可從原材料上解決它在應(yīng)用過程中的防腐問題, 采用“以銹防銹”的思路實(shí)現(xiàn)輸電桿塔的免涂裝、免維護(hù)。主要介紹了耐候鋼在我國(guó)輸電桿塔中的應(yīng)用研究進(jìn)展和工程應(yīng)用取得的重要成果, 包括桿塔用耐候鋼板/ 卷、熱軋耐候角鋼和耐候鋼螺栓等主要原材料的成分設(shè)計(jì)和性能研究, 耐候鋼耐大氣腐蝕行為研究, 以及冷彎耐候角鋼塔、熱軋耐候角鋼塔和耐候鋼管桿的工程應(yīng)用情況。

Abstract:

Transmission pole and tower is one of the most important infrastructures in transmission line engineering projects.Hot-dip galvanising has long been the primary anti-corrosion solution for transmission pole and tower. However, the intermittent hot-dip galvanising industry has been identified as one of the industries that consume large amounts of raw materials and energy and produces numerous pollutants. In addition, transmission pole and tower with hot-dip galvanising corrosion protection need maintenance. Therefore, the development and application of novel anti-corrosion materials are important goals for power industries. In the atmos pheric environment, the surface of weathering steel will form a dense and stable rust layer with good adhesion,which has better corrosion resistance than ordinary carbon steel. The application of weathering steels in transmission pole and tower is an important development direction of corrosion protection. Using weathering steel to manufacture transmission pole and tower can solve the anticorrosion problem in the application process from raw materials, and the idea of “rust to prevent rust” can realize coating and maintenance free for its lifetime. The paper mainly introduces the applications and important research achievements of weathering steel for transmission pole and tower in China, including the composition design and performance research of the main raw materials (such as weathering steel plate, hot roll weathering angle steel and weathering steel bolts), corrosion behaviors of weathering steel in different regional climate, and the engineering application of weathering steel in transmission pole and tower.
