A method is presented to determine the eddy current power losses in the shell of a three-phase cylindrical arc furnace. The effect of electrode phase rotation with unbalanced electrode currents on the induced losses is shown. This study indicates the direct similarity between the induced loss distribution and the nonlinear refractory wear pattern in a furnace. Experimental results on a furnace model are included to support the theoretical work. The measured wear pattern of a section of the refractory lining in a furnace is included to illustrate the corresponding qualitative distributions.
