摘要

Defect of continue casting slab is closely related with technology and working conditions, one productive condition usually leads to the same type of defect. So it has a great practical significance to evaluate the operative process by effective recognition of defect types. In this paper, a damped oscillating signal is acquired by differential method. The defect type of continues casting slab is preliminary qualitative detected via three eigenvalue, the wave peak value(called WPV below), the lagging time of peak(called LTP below) and the peak value difference between the rising and failing edge(called PVD below) which extracting from the differential signal.
