摘要
在我国16个长钢轨焊接基地中,大部分生产线采用了GAAS80系列钢轨闪光焊机,另有成都铁路局、广铁集团等单位的焊轨基地生产线采用了少量K系列固定式钢轨闪光焊机。本文介绍了我国长钢轨焊接基地应用的几种固定式钢轨闪光焊机和我国自主研发的固定式钢轨闪光焊机,详细分析了各型焊机的历史发展、技术参数、机械结构、电源系统和工艺特点。结合我国当前铁路发展的趋势,未来固定式钢轨闪光焊机将朝自动化、智能化和信息化方向发展。
There are 16 long rail welding plants in China, most of the production line of these long rail welding plants use GAAS80 series rail flash butt welder, and a small number of production lines of long rail welding plants in Chengdu Railway Bureau and China Railway Guangzhou Group Co.,Ltd. use the K series fixed rail flash butt welder. This paper introduces fixed rail flash butt welder used in China's long rail welding plants and fixed rail flash welder developed independently in China,and the historical development, technical parameters, mechanical structure, power supply system and process characteristics were analyzed. According to the trend of railway development in China, the future fixed rail flash welder will develop towards automation, intelligence and informaionization.
