铁路客车检修轮轴表面除锈处理工艺分析

Analysis of Derusting Process on Overhaul Axle Surface for Railway Passenger Car

采用喷砂、磨片打磨、角磨机砂轮打磨3种不同的除锈方式,对检修轮轴进行表面除锈试验验证,分析不同处理方式对轮轴基材表面粗糙度、光泽、温度变化、伤害程度的影响。确定喷砂除锈是对车轴伤害最小、最有利于对后续探伤、油漆施工的处理方式。

Three types of derusting methods including sand blasting,sandpeper sanding and angle grinder grinding are selected to verify on overhaul axle surface.The effects of different derusting method on the axle surface roughness,gloss,temperature and extent of injury are analyzed.The results show that the sand blasting is confirmed to be the best derusting process.
