Digital radiographic inspection process for complex shape steel castings
摘 要
分析了某复杂形状铸钢件的几何结构和检测要求，采用非晶硅平板探测器研究了其数字射线成像检测工艺，并与常规射线胶片法进行比对试验。结果表明，数字射线成像法检测灵敏度满足GB/T 5677-2018标准的要求，图像分辨率及归一化信噪比等指标满足GB/T 35388-2017标准的要求，且数字射线成像法与胶片法得到的检测结果基本一致，说明数字射线成像法的检测能力及可靠性可达到AGFA C7胶片法的检测水平，可以用于该铸钢件的质量控制。

Abstract
The digital radiography technology was studied by using amorphous silicon flat plate detector through analyzing the geometry shape and testing requirements of the complex shape steel casting, and results were compared with the conventional film method. The test results show that the detection sensitivity of digital radiography technology meets the requirements of GB/T 5677-2018 and the image resolution and normalized signal-to-noise ratio meet the requirements of GB/T 35388-2017. The test results obtained by digital radiography method and film method are basically consistent, which shows that the detection ability and reliability of X-ray digital radiography method can reach the level of AGFA C7 film method, and can be used for quality control of the steel casting.
