摘　　要：对大型Cr5支承辊的UT检测缺陷位置进行取试分析,判定缺陷性质,结合辊身径向组织分布规律,对支承辊的生产制造工艺提出优化方案,并应用于生产,产品内部质量取得了明显改善。UT defect position of large Cr5 backup roll has been analyzed to determine the nature of the defect.Combined with the distribution law of the radial structure of the roll body,an optimization scheme for the manufacturing process of the back-up roll has been put forward and applied in the production.The internal quality of the product has been improved obviously.

关 键 词：支承辊 超声检测 缺陷分析 工艺优化
