高镍铬离心复合轧辊的提前失效与预防

Introduction of unusual failure types of high Ni-Cr centrifugal composite roll and the prevention measures

介绍了热轧板带生产中所使用的高镍铬离心复合轧辊的性能指标和失效形式 ;分析了其失效原因后指出 :通过选择合适的轧辊强度、硬度和韧性指标 ,调整轧制条件 ,并采用轧辊超声波检验技术 。

The performance indexes and failure types of high Ni-Cr centrifugal composite roll for hot strip mill were introduced It pointed out that the hardness,strength and toughness of roll should be reasonably selected,and the ultrasonic measuring technology must be applied to effectively prevent from unusual failure
