Apparatus for disconnecting a residual portion of a consumed graphite electrode from a permanent electrode which has been lifted out of an electric furnace and which may still be hot, and for connecting a fresh graphite electrode portion to the permanent electrode, comprises a housing for surrounding the electrode assembly in the region of a screw nipple on the permanent electrode. Disposed in the upper region of the housing is an upper clamping means for holding the permanent electrode, while disposed in the lower region of the housing is a lower clamping means which can produce a screwing movement for unscrewing and screwing on the graphite electrode portion. The housing is of a double-walled construction to provide for water cooling thereof.
Apparatus for connecting a graphite electrode from below by nipple means to a permanent electrode which is axially displaceably carried by a carrier device of an electric furnace and which carries a residual portion of a consumed graphite electrode on a lower screw nipple, comprising a housing which is disposed around the permanent electrode in the region of the screw nipple and the adjoining portion of the graphite electrode, an upper clamping means disposed in the upper region of said housing, for gripping the permanent electrode, and a lower clamping means disposed in the lower region of the housing, the lower clamping means being adapted for screwing through a total movement of more than one revolution in an axial region permitting a graphite electrode to be disconnected from and connected to the nipple means on the permanent electrode, the housing having a cylindrical inner wall around an axial space for receiving the electrode assembly, the cylindrical inner wall being closed except for the openings required for the clamping means and being of a double-walled construction, the hollow space defined by the double-walled construction being connected to a coolant supply.
Apparatus for connecting a graphite electrode portion to the lower end portion of a permanent electrode in an electric furnace, comprising:
