ELECTRIC FURNACE.
(Applicatioxfled Feb. 27, 1901.)
(lq Model.)
@W M Mm y um ce my@ ition au matfea uo produ Cla-30G nos carbon blocks s, and thus rapidly-melts the mixture which has been fed into the furnace, and thus a bath is formedwhch gradually penetrates the resisting layer g, which be-- comes more conductive. A temperature is thus gradually produced which nally reaches a normal and invariable' degree corresponding to the minimum of volatilization of the metal if the proper' strength or intensity of electric current be provided. A current, for example, of, say, forty to fifty Watts persquare centimeter of the sectional area of the upper electrode enabl'es this result to' be obtained. As the Work of the furnace proceeds the metal accumulates on the hearth g, where it remains in a fluid condition by reason ofthe superiicial resistance of the layer and its low lthermic conductibility. When the bath of metal has reached the desired height, itis drawn off in the usual manner.
Having now particularly described and as.
certained the nature of this invention and in what manner the same may be performed, I declare thatiwhat I claim is- An electric furnace more especially constructed for the electrometallurgical manufacture of iron, manganese and alloys of these metals, comprising a movable crucible or hearth with raised sides, a cathode mounted ou this hearth Acomprising horizontal carbons d embedded in a layer of powdered ferromanganese and two horizontal carbon blocks s resting on the carbons d for the purpose of priming the `furnace, an upper electrode or anode formed With vertically-movable carbons h inclosed in a casing of crushed slag compressed with tar and resin, a frame in which slides the upper electrode and charging-openings provided in the frame, substan' tially asset forth.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
ALBERT SIMON.
