Abstract:
1. An apparatus for processing iron sinter comprising: a furnace for heating materials for forming hot iron sinter, a cooling system arranged downstream of the furnace for cooling the iron sinter, said cooling system comprising a rotatable cooling carousel, a charging inlet for directing hot iron sinter from the furnace onto the rotating carousel at an inlet station, a plurality of convective cooling stations disposed at circumferentially spaced locations about the carousel, said convective cooling stations each including an air chamber disposed below said carousel and a fan for generating forced air and directing the forced air into the air chamber and in turn upwardly from the air chamber onto an underside of iron sinter as it is carried and moved by the carousel, a plurality of evaporative cooling stations disposed at circumferentially spaced locations about the carousel, said evaporative cooling stations each including a plurality of spray nozzles for directing a cooling fluid onto the iron sinter from an underside as it is carried and moved by the carousel, said fan for each convective cooling station being disposed outside of said air chamber, said liquid spray nozzles of said evaporative cooling stations being disposed within the air chamber of said convective cooling stations such that the discharge of cooling fluid from the liquid spray nozzles within the air chamber is further carried by the current of air discharging from the fan of the convective cooling station upwardly onto the underside of hot iron sinter as it is carried by the carousel, a plurality of temperature sensors for sensing the temperature of the iron sinter as it is carried by the carousel, a controller responsive to the temperatures sensed by the temperature sensors for controlling the flow of fluid from the spray nozzles of the evaporative cooling stations based upon predetermined temperature settings of the controller, and a cooled iron sinter discharge station for removing the iron sinter from the carousel after being cooled by the plurality of convection and evaporative cooling stations.
