摘要： The invention comprises a charging apparatus for melting furnaces, especially for plasma melting furnaces, for the continuous melting of preferably prepared aluminum scrap material.With the help of the proposed solution a controlled and regulated supply of the scrap material along with the prevention of a direct application of the plasma arc or other energy sources directly to the material to be melted, can be accomplished with the simultaneous pre-warming and cleaning of the material to be melted, wherein the metal loss resulting from burning is minimized, the contents of the contaminants within the metallic smelt is reduced and, in addition, an effective environmental protection can be accomplished. This is attained by the provision of an axially movable shaft 4 arranged vertically or tilted in the opening 1 of the furnace and having on the charging side a charging funnel 6 with an exhaust ring nozzle 7. The shaft 4 is guided in a guiding bushing 8 provided with sliding strips, which is welded to the outer wall of the furnace. For the supply of the combustion air as well as for the production of the axial oscillations, the upper portion of the shaft 4 and below the charging funnel 6, a compressed air piping 10 and a mechanical shaker 14 is arranged. The regulation of the charging height is performed by means of a mechanical sensor or a mirror system which is arranged in the shaft 4 or outer of the charging apparatus.FIG. 1 serves for the best illustration of the invention.
