钢轨焊接师:焊花为伴演绎“无缝人生”
本文来源: 新华社 2019-07-23 22:31:39 编辑: 程文超 作者: 王烁

近日,记者走进郑州铁路局郑州工务机械段小李庄焊轨基地,实地探访每年最高焊轨能力达2600公里的现代化工厂,目睹了长钢轨“诞生”的全过程,见识到了“焊轨师”们的“盖世神功”。

新华社郑州5月5日电(记者王烁)高铁时代,“和谐号”动车组列车每天在万里铁道线高速平稳地飞驰,乘客再也听不到铁轨“哐当哐当”的声音,这得益于我国高铁的核心技术——无缝线路。

近日,记者走进郑州铁路局郑州工务机械段小李庄焊轨基地,实地探访每年最高焊轨能力达2600公里的现代化工厂,目睹了长钢轨“诞生”的全过程,见识到了“焊轨师”们的“盖世神功”。

小李庄焊轨基地党支部书记张志勇告诉记者,之所以叫“长轨”,是因为每根钢轨都有500米长。与普通焊接不同,将5根百米钢轨焊接成500米长轨,焊接生产要经过外观检查、焊前除锈、钢轨焊接、焊筋整形、焊后热处理、精矫直、精打磨、质检探伤等十四道工序,最后检验合格才能出厂。

据悉,郑州工务机械段小李庄焊轨基地是中原唯一的钢轨焊轨厂。2008年以来,基地累计焊接钢轨接头近20万个,为京广、郑西、京沪、郑徐等高铁线路以及郑焦、郑开等城际铁路提供了2000多公里的优质长钢轨,数量超过目前全国高铁运营总量的十分之一。

钢轨焊接质量是确保高速列车安全平稳运行的前提,而焊机的焊接工艺参数设置是最为关键的技术。“从钢厂运来的钢轨批次不同,里面的微量元素含量也不同。”基地工艺技术员罗宇航说,只有经过连续25个落锤、15个静弯、3个疲劳试验等10个项点检测检验合格后,才能开始正式生产。 

25岁的汤璐璐来到焊轨厂还不到两年,如今已能够独立担当“最核心”的焊接作业。“尽管设备用的是自动化技术,但有些时候还要靠手感去精调。”只见他一手操作焊机电脑,一只手搭在钢轨的截面上,确保焊接面严丝合缝地在一起。“钢轨接头高低相错的误差不能超过0.2毫米,相当于3根头发丝。”汤璐璐说。

为保障长轨质量,在每焊接500个接头后,长轨要迎来一个重要的“试验”——落锤。罗宇航介绍,落锤试验就是用1吨的铁锤从5.2米高度自由落体锤击钢轨焊头,锤击后的焊头不裂不断,就说明工艺没有问题,反之则要展开“会诊”,及时调整焊接作业参数。

即便通过锤打这一关,每条长轨接头还须接受“长轨医生”的检查,主要是运用超声波探伤仪,对接头的全身进行无损检测。检验合格后的钢轨会烙上“身份证”,上面记录着钢轨材质、出厂日期、生产编号等信息,以此实现质量抽检静态验收和动态跟踪,确保每一根出厂钢轨都优质达标。

2015年,一位外国人录下一段视频:在乘坐京沪高铁时,他将一枚硬币竖立在以300公里时速飞驰的列车窗台上,竟然保持了9分钟不倒。“让硬币竖立9分钟不倒的重要原因之一,就是长轨。”张志勇说,使用长轨就是为了提高火车行进的平稳度。

按照中原“米”字型高铁网络规划,基地又承接了郑万、郑合杭高铁700公里长钢轨的任务。在焊轨师们日复一日的精细操作下,一根根“轨坚强”不断出炉,奠定着高铁之基,让中国高铁越来越快、越来越稳。(完)
