摘要
长定尺钢轨可以大大提高钢轨的整体平顺性,钢轨长尺化生产可以大大提高其成材率。由于探伤后再锯切,可保证钢轨端头的内部质量,增加定尺钢轨的长度,减少焊接接头的数量,提高轨道运行的平顺性及安全可靠性。介绍长定尺钢轨的长度,指出发展长定尺钢轨需要解决的问题,例如长定尺钢轨生产技术改造、运输、焊接及在我国铁路的实施步骤。
The longer length of rail could greatly increase the general smoothness, and the production of longer length of rail can greatlyimprove the rate of use. Cutting rail after brush-burn could ensure the inner quality of rail end, increase the length of fixed-length rail,reduce the number of welding joints and improve the smoothness and reliability of rail operation. The essay introduces the length of longer-length of rail, points out the problems about longer length of rail that need resolving, such as technical innovation of production, transportationand welding of longer length of rail, as well as implementation steps of the longer-length rail in China railways, and puts forward implementationsteps and suggestions of longer length of rail.
