Beschreibung
Zusammenfassung:	A system for feeding reduced iron material is provided which not only reduces cracks of particulate reduced iron material but also feeds the reduced iron material uniformly onto a hearth regardless of the width of the hearth. The system is characterized by including a plurality of material supply systems (4) which are disposed in the direction of width of a moving hearth type smelt reduction furnace, wherein the material supply system (4) is made up of a hopper (10) for receiving reduced iron material and discharging the same through a discharge outlet (10a); a trough (14) for communicating between the discharge outlet (10a) and a material input portion of the moving hearth type smelt reduction furnace and for receiving the reduced iron material discharged from the discharge outlet (10a); an outlet provided on the exit side of the trough (14); and a vibrator for vibrating the trough in the direction of movement of the hearth.
