A single 22-megawatt submerged arc furnace using 25-mil electricity, running 24 hours per day, uses $11,500 of electricity per day, or $4.1 million annually. However, the current energy crunch doesn't bode well for ferrosilicon producers to have access to such low-cost electricity in the future.

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 ...
