Problems solved by technology
[0003] The present invention is to solve the problem that the nodularity degree of nodular cast iron is not easy to measure and the workload is large. It provides a method by letting the nodular cast iron ball roll on the horizontal plane, and then measuring that the nodular cast iron ball does not block the light during the rolling process. The diameter of the ductile iron ball or the degree of nodularity can be judged by the change rate of the light intensity or the light intensity of the unblocked light. It is easy to measure, the measurement workload is small, and the degree of automation is high. It can separate defective products from qualified products.

The invention discloses a ductile iron spheroidization degree non-destructive measuring device and a measuring method thereof, belonging to the technical field of sphere spheroidization degree measurement. Whether the diameter or spheroidization degree of a ductile iron ball is qualified or not is judged by making the ductile iron ball roll on a horizontal surface and then measuring an light intensity of unblocked light or a change rate of the light intensity of the unblocked light during the rolling process of the ductile iron ball. The ductile iron spheroidization degree non-destructive measuring device comprises a controller, a data processing module and a vertical pipe; a horizontal plate is arranged in the vertical pipe; a left rectangular hole and a right rectangular hole are separately arranged on the left and right pipe walls of the vertical pipe above the horizontal plate; a left shading hood and a right shading hood are separately arranged on the outer pipe wall of the vertical pipe at the left and right rectangular holes, and a light emitting mechanism and a light receiving mechanism are separately arranged in the left and right shading hoods; and the data processing module, a control end of the light emitting mechanism, a control end of the light receiving mechanism, a control end of a commutating motor, and a control end of a ball universal rolling mechanism are separately connected to the controller.
Description
technical field [0001] The invention relates to the technical field of measuring the spheroidization degree of a sphere, in particular to a non-destructive measuring device and a measuring method for the spheroidization degree of a nodular cast iron. Background technique [0002] At present, the spheroidization rate is one of the important quality indicators of ductile iron balls, which is generally measured by metallographic method. The process includes: cutting samples from the nodular cast iron ball body, sample polishing, corrosion, microscope observation, etc. The workload is heavy, and only sampling measurements can be carried out, which is not suitable for 100% measurement in mass production. Contents of the invention [0003] The present invention is to solve the problem that the nodularity degree of nodular cast iron is not easy to measure and the workload is large. It provides a method by letting the nodular cast iron ball roll on the horizontal plane, and then m...
