Abstract

A device for the mechanical nippling up of electrode sections on an electrode positioned vertically in an electrode holder in an electric furnace, especially an arc furnace, by means of screw nipples forming the connection. The device comprises coaxial cylinders forming a coupling which can be coupled automatically or by control means with a connector element located on the upper end of the electrode section to be nippled up.
