    摘要: @ A gap (32) between an insertion hole (24) formed in a covering (22) of a ladle (2) and an electrode (20) inserted through the insertion hole (24) is sealed by sealing means (26, 28). The sealing means (26, 28) have a cap seal (28) longitudinally and slidably fitted over the electrode (20). A base seal (26) is hermetically disposed between the cap seal (28) and the covering (22) in such a manner that the gap (32) is provided between the electrode (20) and the base seal (26). The base seal (26) has a gas injection nozzle (38) intended to discharge a gas towards the electrode (20) and another gas injection nozzle (40) intended to discharge the gas downwardly.
    The base seal may be cooled by causing cooling water to be circulated therethrough.
