STEEL SLAG TREATMENT DEVICE AND STEEL SLUG TREATMENT METHOD USING THE SAME

Japanese Patent JP2017015354

A

PROBLEM TO BE SOLVED: To provide a treatment device capable of enhancing reaction speed in carbonation of slag and sharing aging and carbonation of slag, and a slag treatment method using the treatment device.SOLUTION: A steel slag treatment device includes a slag container and a pressure container capable of storing and sealing the slag container. In the steel slag treatment device, a COsupply port of a COpiping for supplying pressurized CO-containing gas to the pressure container is positioned on the lower side in a vertical direction with respect to an exhaust port of an exhaust piping, and a steam supply port of a steam supply piping for supplying pressurized steam to the pressure container is positioned on the upper side in the vertical direction with respect to the exhaust port of the exhaust piping. A steel slag treatment method using the steel slag treatment performs steam aging of steel slag and carbonation of steel slag.SELECTED DRAWING: Figure 1
