Abstract
An electrode seal for use in a metallurgical furnace, the furnace comprising a furnace space heated by electrodes extending through an aperture into the furnace space. The electrode seal comprises at least three sets of shoes in consecutive lateral contact, each shoe having a biasing member for biasing a surface of the shoe toward one of the electrodes thereby allowing the one electrode to longitudinally move within the electrode seal while providing electrical insulation between the electrode and the aperture.
