Abstract: A delivery device for delivering stock material into a blast furnace includes a transition channel for the stock material, a chute for delivering the stock material, a first annular body, coaxial to and outside the transition channel, adapted to rotate about a first axis, and a second annular body, coaxial to and outside the first annular body, adapted to translate along the first axis with respect to said first annular body and/or to rotate about the first axis together with said first annular body. When the second body translates along the first axis, at least one fixed rack rotates at least one toothed wheel and a respective shaft about a second axis transversal to the first axis, thus causing a change in the inclination of the chute with respect to the first axis.

Abstract: A delivery device for delivering stock material into a blast furnace, the delivery device comprising a transition channel for the stock material, defining a first axis; a chute for delivering the stock material, arranged below the transition channel; a first annular body, coaxial to and outside the transition channel, adapted to rotate about the first axis; a second annular body, coaxial to and outside the first annular body, adapted to translate along the first axis with respect to said first annular body and/or to rotate about the first axis together with said first annular body; at least one fixed rack fixed to the second annular body and arranged parallel to the first axis; two shafts, having a same second axis, transversal to said first axis, arranged on opposite sides with respect to the transition channel and crossing said second annular body and said first annular body; at least one toothed wheel, engaging the at least one fixed rack and fixed to one shaft of said two shafts; wherein the chute i

Abstract: A vertical reduction furnace for the production of metallic iron by means of the direct reduction of iron ore (DRI), comprising an iron ore feed zone, an iron ore reduction zone, a metallic iron discharge zone (3), accumulation means (6) communicating at an inlet end with the metallic iron discharge zone (3) and at an outlet end with gas sealing means (7). The accumulation means may accumulate the metallic iron along with the off-gases from the reduction process.
