Title: Bottom electrode arrangement for an electric furance
Inventor: BUHLER KARL
IPC: F27D11/10
Filed: 1984-12-22
Granted: 1988-07-07
Abstract: The shape of the furnace hearth (20) in the area of the bottom electrode (6) is defined within limits given by exponential functions, with minimum and maximum values being given for the ratio of the cross section (AL) of the of the melting bath (13) to the cross section (A) of the bottom electrode (6) in its melting bath contact surface (6', 7'). The electrode is designed in the shape of a truncated cone, with the cone surface enclosing an angle of at least 20 DEG  with the melting bath contact surface. The trumpet-shaped or conical widening of the furnace hearth surface (20) in the area of the bottom electrode makes possible a continuous transition of the current and of the electromagnetic field in this area, by which means the bath movement near to the melting bath contact surface (6', 7') of the bottom electrode (6) is also reduced. The arrangement of the bottom electrode (4) in a protuberance of the furnace hearth (20) protects the bottom electrode (6) from the flow spreading throughout the entire melting bath (13). Moreover, only one metal sump is required in the protuberance in order to initiate a subsequent melting process, and not, as in normal practice, a metal sump which extends over the entire furnace hearth surface (20).
