The Ultrasonic Detection of Macro-Inclusions in Steel

Abstract:

This paper studied the distribution of defects by ultrasonic testing and the source of the defect was verified by SEM/EDS. The results showed that the defects mainly distributed in inner and outer sides closed to the surface of the slabs. The number of the defects in inner side was 1.5~2 times of that in outer side. A window 40mm×180mm inclusion band in 1/8 of the inner side existed. The defects in hot-rolled plate mainly formed due to the bad plasticity and deformability inclusions, such as Al₂O₃, SiO₂ and MgO·xCaO. So decreasing the inclusions in slab was important to decrease the defects in hot-rolled plate.
