To efficiently solidify and dry reduced slag in a solidifying apparatus for solidifying and drying the reduced slag discharged from a steel making process.
The solidifying apparatus 10 includes: a vertical cylindrical treating tank 12 having a treating chamber 14 in which a briquette S is filled; a gas introducing part 28 provided in the lower part of the treating tank 12 and for introducing a gas containing carbon dioxide and having at least ≥100°C into the treating chamber 14; and a gas discharge part 32 provided in the upper part of the treating tank 12 and discharging the gas flowing-in from the gas introducing part 28 and circulating toward the upper side of the treating chamber 14 from the upper part of the treating tank 14. The solidifying apparatus is constructed so that the processed briquette S solidified and dried by the contact with the gas is sequentially discharged from a discharge part 24 of the treating tank 12 and the untreated briquette S is sequentially charged from a carrying-in part 22 of the treating tank 12 to the upper part of a treating chamber 14.
