  • Patent number: 7687018
    Abstract: Means for conveying hot granular material from a loading zone to an arc melting furnace (3), comprising a horizontal trough (1), trough vibration generators that cause the granular material to move along the trough, a sluice gate (4) to regulate the material flow in the discharge zone and a sluice gate to regulate the material flow in correspondence with the loading zone. Separating baffles (5) are arranged inside the conveyor trough defining cells in which the granular material accumulates and considerably improving the effectiveness of the action of the gases that are forced through the granular bed, for instance to prevent oxidation of the hot DRI or to perform an additional reduction process.

  • Publication number: 20090051083
    Abstract: A vertical reduction furnace for the production of metallic iron by means of the direct reduction of iron ore (DRI), comprising an iron ore feed zone, an iron ore reduction zone, a metallic iron discharge zone (3), accumulation means (6) communicating at an inlet end with the metallic iron discharge zone (3) and at an outlet end with gas sealing means (7). The accumulation means may accumulate the metallic iron along with the off-gases from the reduction process.
