摘　要: 我公司生产的轧材(规格为Ф100mm-Ф350mm),月产量在2万t左右,钢中缺陷种类较多,特别是单点夹杂以及其它有方向性的小裂纹,手工超声波检验时,因盲区、噪音等原因极易漏检,为满足生产检验质量及数量要求,我厂于2013年引进了一套加拿大Olympus NDT公司生产的国际领先的相控阵超声检测系统。

Abstract: Company's rolled products( specifications are fromФ100mm- Ф350mm),and per month output is about 20 thousands tons. Defect types of steel are more,especially small crack of single part inclusion and other direction cracks. And due to the blind spot,noise and other reasons detecting could been easily missed by manual ultrasonic inspection. in 2013 the leading ultrasonic phased array testing system of a Canadian Olympus NDT company production was introduced to meet production inspection of quality.
Keywords: phase array; Ultrasonic testing; defect; inclusion
