<p>One current conductor is disposed in series with the arc current below the furnace vessel, and disposed in such a way that the current through this conductor will pass in a direction opposite to the direction in which the current flows through the charge. Additional control magnets or example multipolar arc magnets, fed with low-frequency alternating current are placed in order to rotate the arc and so to cause the wear on the furnace to be evenly distributed in certain extra worn parts to be avoided.</p> |
