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 includes, in performing hot briquetting on a reduced iron aggregate composed of pellet-shaped reduced iron containing an iron component, a step of controlling a particle size distribution of the reduced iron aggregate, and a step of performing hot briquetting on the reduced iron aggregate with the controlled particle size distribution. An apparatus for producing a reduced iron briquette of the present invention includes a reduced iron production facility that produces pellet-shaped reduced iron containing an iron component to form a reduced iron aggregate, a crushing facility that crushes the reduced iron aggregate, a classification facility that screens the crushed reduced iron aggregate, using a sieve having a plurality of sieve meshes, a mixing facility that mixes the reduced iron aggregate having a plurality of particle size levels, separated by the screening, to prevent uneven distribution of the particle sizes within a mold for hot briquetting, and a reheating facility that heats the mixed reduced iron aggregate to a briquetting temperature required for the hot briquetting.
