Apparatus to move and preheat metal material

An apparatus to move and preheat metal material (M) to be fed to a container, comprising a substantially horizontal containing structure, and having an upper wall, a base wall and lateral walls defining an internal compartment said containing structure comprising a support wall, interposed between said upper wall and said base wall, a conveyor for said material, 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 material, a collector for hot fumes, wherein said collector is located below said conveyor inside said internal compartment essentially along the entire longitudinal development of said containing structure, one or more through apertures being made in said support wall to put said conveyor and said collector into fluidic connection, wherein the volume of said fume transit section reduces as it is distanced from said container along the longitudinal development of said containing structure, and the volume of said collector increases in a manner correlated to said reduction in the fume transit section, and wherein in correspondence with one end of said containing structure, opposite the end associated with said container, there is a dynamic sealing element configured to prevent the entrance of air inside the zone where said metal material is conveyed, wherein said dynamic sealing element also has the function of pressing and leveling said metal material entering the containing structure.
