Beschreibung
Zusammenfassung:	A discharge device for a direct-reduction shaft furnace, e.g. of the type used to produce sponge iron from iron ore, comprises a discharge or scraper bar or plate reciprocable beneath the column of charge in the furnace to displace the sponge iron alternately toward one side and the other and thus into respective outlets. The discharge bar or plate is provided with a pair of rods on each side, the rods extending in the direction of displacement. Floating bearings sealingly engage each rod and are connected to the housing. The floating bearings are provided with gas-type seals, motion-compensating members between the seals and the housing, and means limiting the displacement of the seal or packing structure.
