(54) Electrode for high temperature processes and its use


(57) Electrode for high-temperature processes, comprising an active section and a cooling section attached to it and extending into the furnace interior, said cooling section (3) comprising at least one heat pipe (5) with a polytropic heat exchanger in the furnace interior which has an additional cooling system (e.g. 6 in Fig. 1) forthe dissipation of heat. The additional cooling system may comprise further heat pipes, a gas and/or a fluid circulation system, with the cooling fluid being pumped, and/or a heat insulation.
The electrode is intended for use in high-temperature processes, particularly in the production of steel. It is characterized by a safe and flexible manoeuvrability.
