Method and device of detecting attribute of graphite in gray cast iron

The invention provides a method of detecting attribute of graphite in gray cast iron. The method comprises the steps of obtaining attenuation coefficient of a gray cast iron material based on a standard sample; detecting the to-be-detected gray cast iron and obtaining multiple various data aiming at the to-be-detected gray cast iron; contrasting the detected various data to the attenuation coefficient of the gray cast iron of the standard sample and finishing detection of the attribute of the graphite in the gray cast iron. The method can detect the graphite length grade of the gray cast ironmaterial nondestructively and rapidly, can increase the on-site product detection efficiency remarkably in production inspection, is an economic and applicable detecting method and has ease of use andapplicability; in addition, the method is simple, fast, economic, applicable and high in detection efficiency. The invention also provides a method of detecting the attribute of the graphite in the gray cast iron. 本公开提供了种测定灰铸
