Abstract
A system is disclosed for assembling a composite, self-baking electrode for electric arc furnaces. The electrode includes an outer metal ferrule, a central column of prebaked carbon or graphite sections assembled by nipples. New sections are added to the column from carbon paste placed between the ferrule and the central column. The assembling system principally includes a support that is vertically mobile over a length greater than the length of each of the sections. The support suspends the central column. A device is provided for temporarily blocking the column and a clamping device applies a preset torque to a newly added section while the blocking device temporarily blocks the column from movement thereby screwing the newly added section to an adjacently positioned section of the column.
