A method for manufacturing reduced iron agglomerates comprises the steps of supplying iron oxide agglomerates including carbonaceous material on a moving hearth, heating and reducing the agglomerates to yield reduced iron agglomerates while the moving hearth moves in the reduction furnace, discharging the reduced iron agglomerates from the reduction furnace, recovering the reduced iron agglomerates, and removing seized hearth fragments separated from the moving hearth in close proximity to a discharge location or a recovery location for the reduced iron while the reduction furnace is being operated. According to the method, the reduction furnace can be operated for a long period of time without stopping the operation thereof and supply of the iron oxide agglomerates. Consequently, high productivity of the reduced iron agglomerates can be achieved, and in addition, superior quality in high degree of metallization of the reduced iron agglomerates can be obtained since the seized hearth fragments having low degree of metallization are not mixed with the reduced iron agglomerates as a product.
