The electric arc furnace uses the energy radiated from high-power electric arcs to melt steel. A disadvantage of the process is that the intense radiation can erode the refractory lining of the furnace. Empirical work has shown that refractory erosion depends on arc power and voltage and their product has been used as an index of this erosion. However, no theoretical basis has hitherto been presented for the refractory erosion index. This paper considers the electric arc as an ideal cylindrical radiator and proposes a theoretical basis for the observed empirical relationship. A similar index of arc energy into the furnace hearth is also derived. Computer simulation results are presented for a typical 80-ton electric arc furnace.
