A device for manufacturing artificial fish reefs using converter stones is suitable for use with a steelmaking furnace. The products of the steelmaking furnace include an exhaust gas containing carbon dioxide and the converter stones. The device for manufacturing artificial fish reefs using converter stones includes at least one solidifier defining a reaction space suitable for the converter stones, a gas control unit adapted to pass the exhaust gas into the at least one solidifier, and a plurality of Information is connected to the flow controller of the gas control unit. The gas control unit includes a humidifier suitable for mixing water gas into the exhaust gas to form a reaction gas, and the flow controllers are suitable for controlling the composition and flow of the reaction gas so that the The converter stone is carbonated by the action of carbon dioxide in the reaction gas and forms the artificial fish reef.一種以轉爐石製造人工魚礁的裝置，適用於配合一煉鋼爐使用，該煉鋼爐的產物包括一含有二氧化碳的廢氣及該轉爐石。該以轉爐石製造人工魚礁的裝置包含至少一界定出一適用於供該轉爐石容設的反應空間的固化器、一適用於將該廢氣通入該至少一固化器的氣體調控單元，及複數資訊連接該氣體調控單元的流量控制器。該氣體調控單元包括一適用於在該廢氣中混入水氣而形成一反應氣體的加濕器，該等流量控制器適用於控制該反應氣體的組成及流量，使位於該至少一固化器中的該轉爐石受該反應氣體中的二氧化碳作用而碳酸化，並形成該人工魚礁。
