Abstract: Improved results in operating self-baking electrodes are achieved by surrounding that portion of the shell which contains the solid and the molten raw, electrode-forming paste, with a stream of a hot gas, while maintaining its temperature at at least the softening point of the raw paste.

Abstract: Improved results in operating self-baking electrodes are achieved by constantly maintaining a bar made of an electrically conductive material well immersed in a carbon mass contained within a metal shell, measuring the voltage drop between the bar and the metal shell and measuring a ratio between this voltage drop and the electrode current.
