More Information
Summary:In 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 curling medium, thus bein g intensively cooled to the final temperature desired (Fig. 1).
