FIELD: metallurgy.
SUBSTANCE: invention refers to metallurgy, particularly to connection of electrodes for arc furnaces. An electrode rod contains an electrode with end sockets with interior threads and is designed to connect with another electrode by means of a nipple. On the contact surface of the electrode with the other component of the electrode rod and/or on the contact surface of the nipple there is made a facilitating sliding thin layer, for example, out of lubricating substances. By means of this sliding layer electrodes can screw together more strongly into a rod thus a higher unscrewed moment is achieved with higher operation reliability.
EFFECT: upgrading of operation reliability of connection.
