- In order to evaluate the effect of size and shape of crack defect on steel surface quality and mechanical properties, accurate measurement and characterization should be conducted. Aimed at the high measuring difficulty and low accuracy in the existing manual mode, a new series of characteristic parameters was proposed according to the morphological features of crack defect in steel. Through the quantitative analysis of parameters including linear morphological factor, defect equivalent and defect rate, the automatic measurement and numerical characterization of crack defect were realized. The results show that the above method can completely solve the high measuring difficulty of complex crack defect distributed with blocky inclusion and crack, which provides a reliable basis for the quantitative analysis of steel surface quality.
