Abstract
A charging arrangement for shaft furnaces, in particular blast furnaces, comprising a container which is arranged above the shaft furnace and which is subdivided by a separating wall into a lower distributor chamber and an upper lock chamber to which the charging material can be fed from above through a filling hopper. Outside its middle and distributed around its periphery the separating wall includes at least two individually closable bottom openings through which the charging material can be passed from the lock chamber into the distributor chamber. The charging material is fed to the shaft furnace through distributor pipes which connect the distributor chamber to the shaft furnace.
