Abstract

Arc furnace has a rotatable non-consumable electrode which is rotated in the opposite direction to the rotation of the arc. An electromagnetic coil may be provided around the crucible to create a magnetic field which will counteract the magnetic field inherent in the arc discharge. The coil may be energized to position the arc at a desired region in the melt or to achieve counter rotation of the electrode wheel and arc. A number of electromagnets (pref. 3) are arranged around the crucible.
