Abstract

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. <IMAGE>
