ABSTRACT OF THE DISCLOSURE Improved cooling of sponge iron in the cooling re- actor of a multi-stage gaseous reduction system for particul- ate iron ore is achieved by using a hollow foraminous closure plug at the bottom of the reactor. The plug is pivotally mounted for movement from a reactor-closing to a reactor- discharge position and has a cooling gas inlet nipple which, when the plug is in its reactor-closing position, registers with the discharge end of a cooling gas supply conduit to cause cooling has to flow into the plug and through the wall there- of to cool the adjacent portion of the sponge iron bed with- in the reactor. The plug can also be used to distribute hot gas to an ore bed in a reduction reactor.
