Immersion electrode holder for glass melting furnace

摘要

A holder, for a cooled electrode immersed in a glass melt,has a cooled coupling with an external electrode-attachment thread and an electrical supply connection, the novelty being that the holder (2) also has a support ring (3) which (a) encloses the electrode (1) in the region in which it is screwed onto the coupling (7); (b) is a single piece made from a single material block; and (c) is detachably fastened to the coupling and/or to a connection housing (24) which accommodates the coupling (7) and the end of the electrical lead (15) connected to the coupling (7).
