<p>A DC electric arc furnace with a furnace enclosure having a hearth containing a melt and with an arcing electrode forming an arc with the melt and made to angularly deflect and rotate by magnetic means forming a rotating magnetic field in the enclosure, is provided with means for sensing areas of the enclosure receiving a maximum intensity of arc radiation because of an asymmetrical charge in the furnace, this sensing means controlling the speed of rotation of the arc so that the arc rotates faster while directing its arc flare at these areas receiving maximum radiation.</p> |
