Abstract

409,893. Electric furnaces. CORNELIUS, C. E., 14, Grevgatan, Stockholm. April 11, 1933, No. 10810. [Class 39 (iii).] In a furnace comprising metal or alloy electrodes 3 located in a chamber 2 and surrounded by a melt 4, the charge is supported above the melt wholly or in part within the area defined by vertical extensions of the walls of the chamber 2. The melt may be glass or slag and the electrodes may be of iron. A crucible 5 may be provided for containing a metal, alloy or glass charge to be melted. The furnace may be used for heating bars or ingots to be welded, for baking porcelain or brick, or for making iron sponge.
