摘要
Process and apparatus for the continuous melting of scrap in an electric D.C. furnace, in which the D.C. source (23) supplies vault electrodes (4) and hearth electrodes (8) by means of respective feed conductors (7) and return conductors (9). The scrap is fed through an orifice (12). The vault electrode or electrodes (4) are arranged on the other side of the axis of the shaft (1) in relation to the orifice (12). The hearth electrode or electrodes (8) are offset towards the orifice (12), and the return conductor or conductors (9) connected to the hearth electrode or electrodes (8) are led under the bottom (2) of the shaft (1) and as near as possible to the latter, being directed towards the opposite zone of the furnace where the vault electrodes (4) are located, as to generate magnetic fields capable of deflecting the arc or arcs towards a zone set apart from the vault electrodes (4) and located substantially below the scrap feed orifice (12 ).
