摘　　要：钢轨铝热焊粗磨过程中要进行热打磨,本文阐述了铝热焊的焊接工艺流程及特点,论述了焊头粗磨技术工艺流程与方法及铝热焊焊接及粗磨过程注意事项,指出焊接热打磨需要合理控制回缩量,打磨过程中要按照钢轨廓形进行打磨,确保打磨后焊头光滑圆顺,保证质量。In the rough grinding process of rail thermit welding,the hot grinding should be carried out.This paper expounds the welding process flow and characteristics of thermit welding,discusses the process flow and method of welding head rough grinding technology and the matters needing attention in the process of thermit welding and rough grinding,and points out that the shrinkage needs to be reasonably controlled during hot grinding,and the grinding process should be carried out according to the rail profile to ensure that the welding head is smooth after grinding and the quality is guaranteed.
