Estimating the term…
An apparatus for an electric furnace capable of effecting electrode connection and refractory lining repairs independently of each other. Mounted on a common supporting member are an electrode connecting device for suspending a new electrode and a refractory lining repairing device having a revolvable nozzle for blowing the refractory lining patching mixture against the eroded cavities in the lining in such a way that they may be traversed along the supporting member independently of each other. The new electrode suspended by the electrode connecting device is rotated whle being lowered so as to be screwed into the consumed electrode. The eroded refractory lining is repaired with the refractory lining repairing device.
Apparatus for connecting a new furnace electrode to a consumed electrode mounted in the furnace comprising means for releasably holding a new electrode to be connected to the consumed electrode, means for rotating said holding means, means including a universal joint for interconnecting said holding means and rotating means, means for vertically moving said holding means and said rotating means to align the electrodes, and cooperating means carried by the new electrode and the consumed electrode to threadedly interconnect said electrode during rotation of said rotating means, said holding means and said new electrode.
