Summary:PCT No. PCT/AT96/00008 Sec. 371 Date Oct. 15, 1997 Sec. 102(e) Date Oct. 15, 1997 PCT Filed Jan. 22, 1996 PCT Pub. No. WO96/23081 PCT Pub. Date Aug. 1, 1996In order to attain as low a final temperature as possible after as short a period of time as possible in a method of cooling hot briquetted sponge iron (3) under optimum utilization of the cooling medium, the hot briquetted sponge iron (3), in a first cooling step (11), is passed exclusively by a gaseous cooling medium while being gently cooled and subsequently, in a second cooling step (14), is sprayed with a liquid cooling medium, thus being intensively cooled to the final temperature desired.
