项目摘要

Sorel Forge specialises in delivering high quality forged steel to a wide array of Canadian and international customers. In order to ensure the quality of their product, each forging is individually inspected for flaws and internal irregularities using standard pulse-echo technique. The forgings are accepted or rejected based on the result of the ultrasonic inspection. A reliable inspection technique is, therefore, paramount to reduce the number of rejected forgings. Forged steel is an anisotropic, highly attenuative material and the specimens under inspection are very large in size. The consequences of these characteristics are that the standard pulse-echo technique often fails to deliver high quality inspection results. The work done during the Engage grant enabled us to recommend a phased array inspection technique. However commercial phased array transducer cannot be used to perform the recommended inspection technique due to the size of the steel forgings. In the project funded by the Engage Plus grant, the tools developed during the Engage grant will be leveraged to evaluate and validate a custom phased array transducer adapted to the dimensions of the steel forgings manufacture by Sorel Forge. At the end of the project, Sorel Forge will receive the recommended design for a custom phased array transducer adapted to their inspection needs as well as a working prototype.

Sorel Forge专门向加拿大和国际市场提供高质量的锻钢顾客。为了确保产品的质量，每件锻件都要单独检查是否有瑕疵和使用标准脉冲回波技术的内部不规则。锻件的接受或拒绝取决于超声波检查结果。因此，可靠的检测技术对于减少拒绝的锻件数量。锻钢是一种各向异性、高度衰减的材料，检查的规模非常大。这些特征的结果是标准脉冲回波技术往往无法提供高质量的检测结果。在启用接洽奖励期间所做的工作向美国推荐一种相控阵检测技术。然而，商用相控阵换能器不能由于钢锻件的尺寸，用于执行推荐的检验技术。在项目中由Engage Plus赠款提供资金，在Engage赠款期间开发的工具将用于评估和验证与Sorel制造的钢锻件尺寸相适应的定制相控阵换能器锻造。在项目结束时，Sorel Forge将收到定制相控阵的推荐设计传感器适应了他们的检查需要以及一个工作样机。
