ABSTRACT:
An electric furnace electrode seal assembly includes a seal ring mounted on the furnace adjacent the electrode opening. The seal ring is stationary and supports a telescoping arrangement of a plurality of cylindrical water cooled sealing glands that extend upwardly along the electrode from the seal ring. The largest diameter gland can be located on top of the seal ring and the uppermost gland can be the smallest diameter and is supported by the electrode holder. Seals are interposed respectively between adjacent glands and these seals permit vertical telescopic movmeent as well as lateral movement of and slight tilting of the glands relative to each other. The bottom gland can slide on the seal ring to provide for additional lateral movement of the electrode and seal assembly. The assembly prevents leakage of gases and acts as a heat shield.
