Abstract
A wall electrode includes a metal bar adapted to extend through the wall of the furnace, a water-cooled sleeve composed of a material which is a good conductor of heat and electricity, an end member composed of a material which is a good conductor of heat and electricity, and an annular member such as a ring composed of a metal which is heavy and has a low melting point surrounding the bar so that the heavy metal in the liquid state spreads in the space between the bar and the sleeve when the annular member is made to melt during use of the electrode.
