Batch charger for cold top electric furnace

A charger for a furnace having a melt with a topside surface over which is to be distributed charging materials comprising:

• 1) a belt conveyor with a discharge end supported by a telescopic conveyor support assembly and carried on pivoting support means located laterally to the surface to be charged;
• 2) a belt within said belt conveyor which belt has a horizontal run over the surface of the melt and a vertical extent proximate to the support means whereby the belt is redirected vertically;
• 3) a vertical take-up system to support and maintain tension within the belt while it is redirected vertically while running;
• 4) an on-conveyor supply bin for the telescopic conveyor support assembly, carried by the support means and positioned to deliver charging materials to the belt conveyor, and
• 5) rollers to support the belt conveyor, a portion of which rollers are to be elevated, the rollers to be elevated being interconnected by articulated links and wherein the charger includes a roller-take-up system to elevate said portion of the rollers vertically when the telescopic conveyor assembly is retracted,
• wherein the support means is mounted on tracks with two outer ends, the charger comprising two fixed supply silos respectively provided at the two outer ends of the tracks to permit the supply of charge to be delivered to the on-conveyor supply bin at two locations while the telescopic conveyor support assembly is engaged in distributing charging materials over the top-side surface of the crucible.

• 3) a vertical take-up system to support and maintain tension within the belt while it is redirected vertically while running,
• wherein the support means is positioned so that, with pivoting combined with the extension and contraction of the telescopic conveyor support assembly, the discharge end of the belt conveyor will be positionable over substantially the entire topside surface of the melt which is to be charged.
