| 中文摘要: |
| 轧辊体积大且辊面状态又不好，尤其是热轧辊的表面常有氧化膜和微裂纹，在测量时又不能损伤轧辊表面，因此，轧辊残余应力的测量较困难。为验证临界折射纵波法测轧辊表面残余应力的准确性，用超声波法、X射线法和盲孔法对同一试件进行了应力测量。对这3种测量方法所测得的结果进行比较后，评价超声波法的可靠性和有效性。试验结果显示：临界折射纵波法测试的应力值与X射线衍射法和盲孔法测试的结果具有较好的一致性。 |
| 英文摘要: |
| The residual stress measurement of roller is very difficult because that the roller has gigantic volume, the surface is out of order and especially there are oxide film and microcrack. In order to test the veracity of the method of the critical refracted longitudinal wave measurement (CRLWM) , the CRLWM method, the X radial method and the dead hole method were employed to test the residual stress, and the test result of this three methods was compared to evaluate reliability and validity of CRLWM. The result shows that the result of all of the test method is consentaneous. |
