摘要
从焊接设备、钢轨焊前选配、人员素质及管理等方面分析引起钢轨焊接接头错边量超标的原因。重点针对钢轨端部不对称度对接头错边量的影响,介绍焊轨基地焊前配轨的具体实施方法。提出建立设备维修和保养制度、焊前合理配轨以及加强第三方监督等控制错边量的措施。
The article analyzes the reasons for deviation values exceeding the allowed figures in welded rail joints with a view to welding equipment,preweld rail matching, personnel quality and management. It introduces the specific implementation method for preweld rail matching at the welded rail site by focusing on the impact of the degree of dissymmetry at rail ends on the deviation values in joints. It proposes establishing the equipment servicing and maintenance system,rationally match rails before welding and strengthen measures controlling deviation values,including supervision by a third party,etc.
