本报记者 唐佳丽 初秋时节，全国各地在建高铁项目快马加鞭。在位于沈阳市苏家屯铁路编组站西侧的中铁九局三公司沈 阳智能建造基地厂房里，高铁轨道板正在加紧生产。生产管理部副部长王言翰蹲在一块轨道板前，聚精 会神地观察、触摸，好久没"动窝儿"。 一旁的工友忍不住了，"这板子摸上去平整得很，侧面看像镜面似的闪着光，质量过硬，不差啥了。" 看王言翰向实验室走去，项目书记杨振华笑着说："看，他这钻劲儿，又上来了！" 从一名普通的中专生，成长为高级工程师、试验员特级技师，王言翰凭的就是这股子爱钻研的劲头。 中国高铁在时速350公里运行时，立在窗沿上的硬币能够不倒，高平整度的轨道板起到了重要的作用。 2018年，王言翰开始从事高铁轨道板的质量管理工作。彼时，高铁轨道板平整度合格率已经达到了 99.8%，但在王言翰看来，这还远远不够。经过反复试验，他发现，问题出在轨道板的蒸汽养护环节。 那段时间里，他一直住在厂里，在工友看来，"他的钻劲儿一上来，有点疯狂，不停地做着试验，忘记 吃饭是家常便饭。" 这只是王言翰和伙伴获得的成绩之一。多年来，王言翰扎根工程一线，凭借对技术创新的执着追求，在 高铁轨道板研发及智能建造领域持续深耕，为 ...
