摘　　要：针对榨糖用榨辊在修补后,补焊位置产生残余应力,引起榨辊变形的问题,首先分析了残余应力产生的机理及其分布情况,根据榨辊残余应力的分布情况,制定了振动时效处理的方案,对支撑位置进行了选取。依据设计方案,在现场,针对榨辊进行振动时效处理。结果表明采用振动时效方式可以有效地消除榨辊修补后的产生的残余应力。Abstract：According to the sugar with roller after the repair, repair welding position residual stress and deformation problem caused by roller, the mechanism and distribution of residual stress was analyzed firstly. According to the distribution of the residual stress of the roller, the vibration aging treatment scheme was put forward and support position was selected. According to the design scheme, in the field, vibration aging treatment for mill roller was carried out. The results show that the vibration aging method can effectively eliminate the residual stress after the mill roller repair.
