Abstract
The device for charging metalliferous materials 7 into a furnace 3 compri a charging tube 1, inside which are arranged supports 8 distributed over an entire non-straight section of this, for example similarly to the stairs of a flight of stairs descending towards the furnace. Passages are provided between the supports 8, and means 10 for the vibration of the supports are provided. The materials progressively descend on the supports 8 towards the furnace and are simultaneously preheated by the hot gases introduced into the tube, circulating through the materials and via the passages 9 and extracted via the outlet orifice 5.
