In this paper blast furnace slag with different content(0%,15%,25%,35%) was selected to carry out quenching and tempering reconstruction on steel slag,and then high-temperature gas quenching had been performed.Influence of gas quenching behavior on the elimination of f-CaO by reconstructed slag had been investigated.The results show that gas quenching is beneficial to the digestion of f-CaO in steel slag.The smaller particle size of steel slag can achieve better the digestion efficiency.XRD and mineral phase analysis show that after gas quenching the mineral phase composition of steel slag is composed of glass phase,RO phase,dicalcium silicate,periclase and so on.
