Abstract
Electrical connecting device to be placed in contact with a molten metallic mass, comprising an elongated metallic body (5) introduced through the wall of a container, to be placed in contact with the metallic bath by one of its ends, the other end constituting a terminal portion (8) projecting to the outside of the container wall, a sleeve (9) made of good thermal and electrical conductive material surrounding and contacting the terminal portion, the sleeve being connected to a charged electrical source and cooled by circulation of a cooling fluid. The device is used when contact between an electrode and a molten mass is required, and eliminates the risk of tapping from excessive melting of the electrode.
