超声波探伤法做为一种检查轧辊内部缺陷的无损检测方法,在控制热轧复合工作辊结合层失效方面有着较其它无损检测方法无可比拟的优越性。实现超声波探伤在控制热轧工作辊结合层失效方面的过程跟踪应用,可以最大限度地实现上机轧辊安全无事故,最大限度地减小轧辊事故损失,从而实现轧辊的可靠使用。 As a non-destructive testing method for inspecting internal defects of roll, ultrasonic flaw detection method has more advantages than other non-destructive testing methods in controlling the failure of hot-rolled composite work roll bonding layer. Realizing the process of ultrasonic flaw detection in controlling the failure of the hot-rolled work roll combined layer can realize the safe and accident-free operation of the upper machine roll and minimize the loss of the roll accident so as to realize the reliable use of the roll.
