  • Patent number: 6026113
    Abstract: Method for the electromagnetic stirring of the liquid metal (14) in direct current electric arc furnaces which include a hearth (35) defined by a floor (13) and by side walls (15), a central cathode (11) cooperating with anodes (12) arranged on the floor (13) of the furnace and fed by a main current (I.sub.0), wherein there is an electromagnetic system generating a magnetic field inside the liquid metal (14) whose vertical (B.sub.z) and radial (B.sub.r) components interact respectively with the radial (J.sub.r) and vertical (J.sub.z) components of the overall current present in the liquid metal (14). The method and device use a first electromagnetic system including at least a first winding (19) through which a current (I.sub.1) flows and operating from inside the floor (13) and the walls (15) of the hearth (35), and a second electromagnetic system generating a secondary induced current (I.sub.3), between adjacent anodes (12), which circulates through the liquid metal (14).
