ABSTRACT An apparatus for preheating and charging scrap material comprises a throat section (38) having at one end thereof a material charging inlet (37) connected to a furnace shell (2), the throat section extending laterally and upwardly obliquely, a heat exchanger section (39) connected to the other end of the throat section (38) and extending upwardly, a sealing section (42) above the heat exchanger section (39), material supply means (43) for supplying the scrap material into the sealing section (42), an exhaust duct (53) formed at the heat exchanger section (39) just below the sealing section (42) and connected to an exhaust system (58) and a material delivery device (46) disposed at the other end of the throat section (38) for delivering the scrap material (13) from the heat exchanger section (39) to the material charging inlet (37). The scrap material (13) is substantially continuously charged into the furnace shell (2) while preheated by the high-temperature exhaust gases from the furnace shell (2).

Dispositif utilisé pour le préchauffage et le chargement des rebuts comprenant un gueulard (38) muni à une extrémité d'une entrée de chargement (37) reliée à la cuve du four (2); le gueulard s'étendant latéralement et obliquement; un échangeur thermique (39) rattaché à l'autre extrémité du gueulard (38) et se prolongeant vers le haut; une section d'étanchéité (42) située au-dessus de l'échangeur thermique (39); un mécanisme d'alimentation en rebuts (43) pour diriger les rebuts jusqu'à la section d'étanchéité (42); une conduite d'évacuation des gaz de combustion (53) constituée à l'échangeur thermique (39) juste sous la section d'étanchéité (42) et reliée à un système d'évacuation des gaz de combustion (58) et un dispositif de transport des rebuts (46) placé à l'autre extrémité du gueulard (38) pour acheminer les rebuts (13) de l'échangeur thermique (39) jusqu'à l'entrée de chargement des rebuts (37). Les rebuts (13) sont essentiellement chargés de manière continue dans la cuve du four (2) tout en étant préchauffés par les gaz de combustion à haute température qui proviennent de celle-ci.
