ABSTRACT:
A method of treating, in a vertical grate furnace, raw materials in an iron reduction process is disclosed. The raw materials are fed onto a grate-containing section which is separated from at least one other section of the grate furnace. Subsequently, the grate-containing section is attached to the other section or sections by moving the other section or sections upwardly or downwardly so as to achieve and maintain gastight conditions between the grate-containing section and the other section(s). The raw materials then undergo preliminary heat treatment in the grate furnace. Finally, the grate is tilted to discharge the treated materials from the grate furnace through an outlet provided on the side wall of the furnace.
