Electric direct-current scrap-melting furnace

摘要

An electric direct-current metal-melting furnace, comprising a vessel (1) having a bottom (11), at least one consumable electrode (2) and at least one fixed electrode (3) which are fed by respective conductors (22; 5). A magnetic screen is interposed between the batch and a part of the conductors connected to the current source (4), so as to master the deflection effects on the arcs attributable to the magnetic fields generated by the conductors. The magnetic screen is arranged along the bottom (11) of the vessel (1), so as to cover at least that part of the bottom which surrounds each connection of a hearth electrode (3) and at least part of the corresponding return conductor (5).
