PCT No. PCT/EP94/03815 Sec. 371 Date Jun. 27, 1996 Sec. 102(e) Date Jun. 27, 1996 PCT Filed Nov. 17, 1994 PCT Pub. No. WO95/14793 PCT Pub. Date Jun. 1, 1995A charging device for a shaft furnace with a lower bell comprises lower means of blockage allowing an upper hopper to be isolated in a sealed manner from a lower hopper and allowing the retention of the charging material. In their open position, these lower means of blockage are positioned so that they unblock a free central passage for the flux of material. This flux is established in the form of a compact and focused flux. Means for moving the lower bell are positioned so as not to disturb the focusing of this flux. Positioned above the lower bell is a deflecting surface, which causes the focused flux to diverge with axial symmetry. Inter alia, a better symmetry in the filling of the lower hopper is obtained. |
