铝热焊接技术作为钢轨无缝连接的重要技术之一,具有设备简单、操作方便、快速高效等特点,目前在铁路上已被广泛采用。然而在港口工程的钢轨焊接中,应用铝热焊接技术的工程实例并不多。结合曹妃甸通用码头二期工程中的钢轨焊接施工,介绍铝热焊接技术的基本原理,施工工艺流程和效果,说明该工艺的先进性及可操作性,供类似施工参考。
Aluminum heat welding technology as one of the important seamless rail technology, with equipment is simple, easy to operate, fast and efficient and so on, the current railway has been widely adopted. However, in the rail welding of port engineering, there are not many engineering examples applying aluminum thermal welding technology. Combined with the rail welding construction in the second phase project of Caofeidian General Wharf, the basic principle, construction process and effect of aluminum thermal welding technology are introduced, which shows the advanced and operability of the process for similar construction reference.
