Claim:
1. An apparatus for continuously conveying and pre-heating a metal charge inside a container of a melting plant, comprising: a conveyor channel having lateral walls and a bottom wall that define a substantially U-shaped cross section, a hood disposed above said conveyor channel defining an expansion chamber, inside which at least part of fumes exiting from said container advance, apertures defined by said lateral walls of said conveyor channel, an elongate activator extending longitudinally along at least part of the conveyor channel, wherein said activator comprises elongate conveyor walls extending longitudinally along a length of the activator, the elongate conveyor walls are inclined and convergent to each other and toward said bottom wall of said conveyor channel bottom, so that a narrower section formed near convergent ends of the conveyor walls limits the quantity of metal charge remaining cold in a central zone on the bottom of the conveyor channel.
