Abstract：One important characteristic of hot metal dephosphorization with low basicity slag is to form low basicity, high oxygen potential slag. The slag of 1.31.8 basicity and 20%25% w(TFe) and ＞ 0.20 m3/(min·t) bottom blowing intensity were used for experiment of dephosphorization of hot metal containing 4.0%w(C), 0.1%0.3% w(P) and 0.4%w(Si) by combined blowing. The results show, that phosphorus partition ratio of around 200 and dephosphorization rate of ＞90% can be obtained. The effect of oxygen blowing parameters and bottom blowing intensity is discussed.
