ABSTRACT:
A device for mounting a self-baking composite electrode for an electric arc furnace, which includes a hollow metallic shell, a central column of graphite or pre-baked carbon comprising a plurality of elements fitted together by means of nipples. A carbonaceous paste is disposed between the shell and the column. The column is suspended from a support which is movable in a vertical direction with respect to the shell, along a length which is greater than the length of each of the elements. The invention is particularly relevant to furnaces for the production of silicon by carbothermic means.
