    摘要: A method for monitoring wear of an electrode in an electric arc furnace comprising the steps of:

    taking a digital picture of the still incandescent tip of the electrode;
    applying a numerical edge detection filter to the digital picture so as to obtain a filtered image wherein abrupt changes in light intensity are represented as contour lines; and
    analysing the contour lines to determine the shape of the electrode tip and the presence of cracks.
