Abstract
The disclosure is directed to an elecrode purge sleeve assembly for high temperature oxidizable electrodes used in electrical heating of molten material and more particularly a purge sleeve for glass melting furnaces wherein a standard size tube of high temperature material slightly larger in its interior dimension than the exterior of the electrode extends over the portion of the length of the electrode subject to degradation and is sealed thereto as well as being supported thereby, the sleeve being arranged to receive an inert gas under low pressure to prevent seepage of atmospheric gases to the portion of the electrode being protected.
