DC arc furnace uses a single solid carbon electrode as the cathode, and produces a DC arc to an anode in the bottom of the furnace (Figure 4). The arc is normally an open or semi-submerged one (Naiker, 2006). Raw materials can be charged either directly into the furnace, or by using a hollow electrode. The DC arc route was designed mainly to ...
