| Abstract: | The internal and surface cracks in rolls were detected with magnet as exciting source. Quantitative detection of cracks was realized by the establishment of mathematical model according to magneton theory and quantitative analysis of crack signals based on the piecewise cyclic approximation of neural network. Simulative test on ferromagnetic material was satisfactory. |
