ABSTRACT:
A carbon electrode surrounded by a protective globe in a fusion refining electrolysis process. The protective globe is self-supporting, gastight and thermally stable. The protective globe is spaced from the carbon electrode by a predetermined distance. Also, there is a predetermined distance between an end of the carbon electrode to be immersed in a melting bath and an open end of the protective globe through which projects the carbon electrode. A preheating process requires the electrode to be initially preheated over the melting bath, then its exposed end is immesered into the melting bath while not immersing the protective globe, and finally immersing both the electrode and the protective globe.
