Φ950mm穿孔轧辊镶套修复

INSETTING PROCESS FOR RECONDITIONING OF Φ950mm PIERCER ROLL

介绍了冶钢集团公司170无缝钢管厂对旧的Φ950mm穿孔轧辊在不拆卸轧辊轴承的情况下进行镶套修复的理论计算和工艺。旧穿孔轧辊的修复成功，延长了穿孔轧辊轴承的使用寿命，避免了更换轧辊造成的损失，节约了维修费用。

The paper involves relevant theoretical calculation and technology with respectiveto the insetting process for reconditioning the Φ950mm piercer roll without removal of the rollbearing, which was conducted by 170 Seamless Steel Tube Plant, Yegang Group Co. Successfulrconditioning of the used piercer roll has prolonged the service span of the roll and avoided possibleloss due to changing of the roll,hence,reduced the maintenance cost.
