Abstract

262,535. Raeder, J. K.. B., and Aktieselskabet Raeders Elektroglasovn. Sept. 17, 1925. Electrode furnaces. - In a furnace for glassmaking the electrodes are arranged at a distance from the region of highest temperature and are completely immersed in the melted glass, the area of the electrode exposed to the glass being considerably greater than its cross-section where it passes through the furnace wall. The form shown is adapted for three-phase current. The electrodes E1, E2, E3 are flat and built into the furnace walls ; their faces may be grooved to diminish the current density which should be from 3 to 9 amperes per square centimetre. The electrodes are placed in a charge section A of the furnaces, a cooling section C and a discharge chamber C1, the greatest heating taking place in a comparatively narrow chamber B connecting the chambers A, C. The materials are preheated in a chamber 9 in the roof of the furnace provided with feeding- hoppers T, T1 and scrapers and conveyers R. The materials should be dried before entering the heating chamber, and the different materials may be delivered separately so as only to mix near the charging opening. A wall W retains the materials near the charging opening until they are melted. Several heating circuits may be provided so as to allow of adjustment of the heat in different parts of the furnace. Specification 15793/92 is referred to.
