In order to find out the causes of 16MnR plate disqualification by ultra-sonic test,the samples from the flaw location are observed and detected with scanning electron microscope and energy spectrum to analyze the microstructure and component.

为找出16MnR钢板超声波检测不合的原因,在检测缺陷部位取样,借助电子显微镜和电子探针,对钢板组织和微区成分进行了分析。

The result shows that the main product causing QO is Q345 series low-alloy steel and unqualified property,unqualified thickness,deficient dimension and petted surface are the main QO items.

运用MINITAB软件对济钢中厚板厂2005年质量异议情况进行分析,可知Q345系列低合金钢是产生质量异议的主要产品,性能及厚度不合、短尺及凹坑是主要异议项目,加热及轧制制度不合理是产生质量异议的主要原因。
