PROCESS FOR CONTINUOUS MELTING OF SCRAP METAL IN A DC ELECTRIC FURNACE, AND ELECTRIC FURNACE FOR IMPLEMENTING THAT PROCESS

摘要

The invention relates to a process for the continuous melting of scrap in an electric direct current oven as well as an oven for carrying out such a process. The direct current source feeds the top and bottom electrodes by respectively supply and return conductors. The scrap is fed through an opening. The arch electrode (s) are located on the other side of the axis of the tank relative to the opening. The sole electrode (s) are shifted towards the opening side and the return conductor (s) connected to the sole electrode (s) are passed under the bottom of the tank and as close as possible to it, directing them towards the opposite zone of the furnace where the vault electrodes are placed, so as to produce magnetic fields capable of deflecting the arc (s) towards a zone separated from the vault electrodes and placed substantially below the scrap supply opening .
