在安装从瑞士Schlatter公司引进的GAas80型焊轨机进行调试的过程中,用包钢P_(74)60公斤/米新型钢轨进行了大量的焊接试验,取得了一些经验,提出一种能满足线路铺设质量的焊轨工艺。并且研究出恒低压烧化直线,解决了P_(74)60公斤/米高碳钢轨闪光对焊工艺中由于粘焊缺陷而带来的焊轨质量不稳定这一最难克服的工艺性问题。此外,还找出焊接钢轨接头去瘤后重打磨焊缝时引起焊轨接头质量严重下降的原因,对提高无缝线路的焊轨质量有普遍的意义。
During the commissioning of the GAAS80 welding machine introduced from Schlatter in Switzerland, a large number of welding tests were carried out with the Ba74 P60 (74) 60 kg / m new rail and gained some experience. Laying quality welding process. In addition, constant straight line of low pressure burning was developed to solve the most difficult process problem of unstable welding quality due to stick welding defects in P74 (74) 60 kg / m high carbon rail flash butt welding process. In addition, it also finds out the reason that the quality of the welded joint caused by the welding rail joint after grinding and re-grinding the welding joint is serious, which has a universal meaning to improve the quality of the welded rail of the seamless line.
