Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an agglomeration process of a steel dust generated from a steel making process for the purpose of recycling, and is supplied to a converter furnace or reduction furnace directly. SOLUTION: The agglomeration process of the steel dust is composed of adding 2-15 mass% unslaked lime to steel dust, mixing them, extruding them and manufacturing a formed body, stacking this formed body below 2 m in height, and maturing inside of a house. Then, in the agglomeration process of the steel dust, the quantity of the metallic iron contained in formed body is more than 5 mass%. COPYRIGHT: (C)2004,JPO
