Abstract
137,811. Norske Aktieselskab for Elektrokemisk Industri Norsk Industri-Hypotekbank. Jan. 17, 1919, [Convention date]. Electrode furnaces.-An electrode is made by tamping raw carbonaceous material into a metal casing and heating first to a comparatively low temperature, preferably in the furnace in which the electrode is to be used, a part of the heat being produced by current entering the mass through the casing. The electrode may be baked at about 600‹ C. before use in the furnace, to harden the carbonaceous mass sufficiently to withstand expansion stresses. When employed directly in the furnace, the casing is preferably kept comparatively cool until the mass is baked. Fresh lengths of casing can be attached as required and filled with the mass. At starting, some coke may be placed in the furnace to connect the electrode casing to a bottom electrode. When the furnace is hot and the end of the electrode is baked, the coke is withdrawn. The electrode casing b may have holes e for escape of gases during baking, and internal ribs c, with or without right-angled projections, to improve the connexion between the casing and electrode mass. Specifications 116,853 and 119,018 are referred to
