离心复合无限冷硬铸铁辊由于为多种材质复合制造,工艺复杂,难以用一种简单的方法有效地对轧辊进行检测,本文介绍了对该类轧辊工作层缺陷进行全面超声波检测的方法和要点。
Centrifugal composite infinite chilled cast iron roller is complicated to manufacture by a variety of materials, and the process is complex. Therefore, it is difficult to measure the roller effectively with a simple method. This paper introduces the methods and key points of comprehensive ultrasonic testing for the working layer defects of such rollers. .
