内容摘要:
轧辊的无损检测通常用超声波探伤仪进行。冷轧辊探伤标准中通常把辊身依受力情况分成表面区、中心区和中间区,然后依断裂力学原理分别规定各区允许存在的缺陷的临界尺寸。Nondestructive testing of rolls is usually carried out by ultrasonic flaw detectors. In the testing standard of cold roll,轧辊, the roll body is usually divided into the surface area, the center area and the middle area according to the force condition,轧辊采购, and then the critical dimensions of the defects are allowed in e......
