Abstract

590,250. Self baking electrodes. COMPAGNIE DE PRODUITS CHIMIQUES ET ELECTROMETALLURGIQUES ALAIS, FROGES ET CAMARGUE. April 12, 1945, No. 9129. Convention date, Jan. 18, 1944. [Class 39 (iii)] The supporting and current-supplying rods b of continuous self-baking electrodes are adjusted in turn as the electrode a is worn, by withdrawing each rod, introducing a quantity of electrode paste j into the hole and replacing the rod. The paste is rapidly baked, being in the hot baked portion of the electrode, and mechanical and electrical connection between the rod and the electrode is re-established. The rods are slightly tapered in their length and are somewhat sharpened at their ends b'. They are first loosened by turning before withdrawal. The self baking electrode may consist of carbon dust and pitch and is continuously filled up at the top inside the sheath d in operation. During the withdrawal of a rod it is preferably allowed to remain partly withdrawn for two hours so that the heat of the rod may bake the walls of the hole slightly to prevent crumbling.
