本文介绍利用超声波检测轴承套圈在锻造、热轧过程中由于加热温度过高或加热停留时间过长而出现的过烧。该方法对直滚道轴承套圈尤具有灵敏度高、可靠、容易判断和不需要增加特殊装置等优点。
This article describes the use of ultrasonic testing of bearing rings in the forging, hot-rolling process due to overheating or heating to stay too long overheating appeared over-burning. The method has the advantages of high sensitivity, reliability, easy judgment and no need to add special devices to the straight raceway bearing rings.
