Cases Analysis of Nonconformity in Ultrasonic Flaw Detection for Steel Plates

Abstract:

Article Preview

The Optical Microscope and Scanning Electron Microscope were used to analyze the causes of Nonconformity in ultrasonic flaw detection for three steel plates. The metallographic and energy spectrum analysis show that the main reasons were inclusions, porosity and cracks respectively, which were caused by the slag inclusion, center porosity and center segregation of the billets. Improving the quality of the steel water and optimizing continuous casting process could reduce the defects, and increase the percent qualified in ultrasonic flaw detection.
