PROBLEM TO BE SOLVED: To provide a solidified material of steelmaking dust for the purpose of recycling it, which does not contain an excess additive such as a binder, has superior handleability, and is inexpensively manufactured by solidifying steelmaking dust produced in a steel production process with the use of a melting furnace; a manufacturing method therefor; and a manufacturing apparatus therefor. SOLUTION: The solidified material B of steelmaking dust is formed by charging the dust 11 mainly containing iron and its oxide produced in the steel production process into a forming die 7, and compacting it. A compacting pressure (MPa) with respect to the cross section area x (mm<SP>2</SP>) is in a range of the expression: 5≤P≤-96.785ln(x)+958.97. COPYRIGHT: (C)2006,JPO&NCIPI
