<p>When operating an electric furnace, each electrode is surrounded by an open-ring duct, placed on the furnace roof and fixed with respect thereto, from which pressurized water is delivered, with different angles with respect to the electrode surface itself. A cooling effect is thus obtained that is additional with respect to the one obtained, in a known way, from water delivered immediately below the clamping vice. In this way the oxidation consumption of the electrodes further highly decreases.</p> |
