移动式交流钢轨闪光焊机

摘要

移动式钢轨闪光焊机是无缝线路建设施工中的重要设备,其性能直接影响钢轨焊接接头的质量。鉴于进口的移动式闪光焊机价格昂贵,我国铁路科研院所进行了移动式交流钢轨闪光焊机的研制工作。从焊机总体结构、焊接主电路、系统控制、液压传动等方面,介绍移动式交流钢轨闪光焊机的组成及原理,概括我国自主开发研制的该种焊机的特性。%Mobile flash butt welding machine is an important equipment of continuously-welding-rail（CWR） building because its performance directly affects the quality of rail welding joints.Due to the fact that imported mobile flash butt welding machine is too expensive,China railway research institutes carry out the research and development of a new mobile flash butt welding machine.This article introduces the component and principle of the mobile AC flash butt welding machine which is developed by our country independently and summarize the features from the aspects of structure,main welding circuit,control system and hydraulic drive.
