<p>PROBLEM TO BE SOLVED: To make it possible to further reduce the irregularity of aging as compared with prior art by making it possible to conduct the aging of steelmaking slag for a further shorter time as compared with the prior art. SOLUTION: When the slag generated as by-product in steelmaking step is treated, high temperature slag S is contained in the sealed chamber 2a of a high pressure vessel 2, water supplied from a water supply nozzle 23 is added to the slag S, steam is generated by utilizing the potential heat of the slag S, and the slag is aged under the steam pressure raised in the chamber 2a, and when the steam pressure in the chamber 2a becomes an axcess, a relief valve 27 is suitably opened to be leaked.</p> |
