Study on Ultrasonic Test Defects Causes of Medium Plate


Article Preview

In this paper,Q345E steel as the object of study,analysis of several typical internal defects of UST to explore the reasons for failure caused by UST testing.The results show that: the center segregation of Mn/S is likely to induce center segregation structure of P+B with a whole cleaning micro-cracks,large size spherical oxide of Si/Ca is an important incentive for causing micro-cracks;Billet board defect detection defect likely to cause an important reason;crack at the alloying elements sharply higher than the matrix composition.Billet defects is an important reason to cause steel surface defects;the alloying elements in place nearing the crack sharply higher than the matrix composition.
