Apparatus to move and preheat metal material

An apparatus to move and preheat metal material to be fed to a container, the apparatus comprising:

• a horizontal containing structure including:
• an upper wall, a base wall, and lateral walls defining an internal compartment, the horizontal containing structure having a first end configured to be associated with said container and a second end opposite of the first end,
• a support wall interposed between said upper wall and said base wall, the support wall including one or more through apertures,
• a conveyor for said metal material, the conveyor defined by said support wall, said lateral walls, said upper wall, and said base wall,
• a fume transit section defined between said upper wall and said metal material when conveyed by the conveyor, and
• a collector for hot fumes, the collector located below said conveyor inside said internal compartment along an entire longitudinal development of said horizontal containing structure, the one or more through apertures fluidly connecting said conveyor and said collector, wherein said fume transit section has a volume that reduces as said fume transit section is distanced from said container along the longitudinal development of said horizontal containing structure, and said collector has a volume that increases in a manner correlated to said reduction in the volume of the fume transit section;
• a dynamic sealing element in correspondence with the second end of said horizontal containing structure, a portion of the dynamic sealing element is located above a part of the upper wall of the horizontal containing structure to which the dynamic sealing element is attached, and the dynamic sealing element configured to prevent air from entering a zone of the internal compartment where said metal material is conveyed and to press and level said metal material entering the horizontal containing structure;
• a suction unit connected to said collector and in a position below said conveyor at the second end of said containing structure, the suction unit configured to take in said hot fumes through said one or more through apertures and through said collector;
• and
• a suction pipe at the second end of said containing structure for sucking up air that has entered due to interspaces between the metal material and said dynamic sealing element and the hot fumes from the container that reach a loading zone of the conveyor.
