Abstract

Proposed is a method for producing a reduced iron briquette that can improve both the apparent density and strength thereof when briquetting reduced iron through hot briquetting. The method for producing a reduced iron briquette of the present invention is a method for producing a reduced iron briquette including performing hot briquetting on a reduced iron aggregate including pellet-shaped reduced iron containing an iron component, using briquetting rolls, and thus briquetting the reduced iron aggregate, the method also including performing hot briquetting on the reduced iron aggregate by changing a rotation speed of the briquetting rolls and/or a gap between the briquetting rolls in accordance with a T.Fe content of the pellet-shaped reduced iron. As a preferred embodiment, the rotation speed of the briquetting rolls is changed to be slower and/or the gap between the briquetting rolls is changed to be narrower as the proportion of gangue components is higher.
