The experimental results indicated that the lower liquidus temperature and the better viscosity stability lay in the area of MgO = 5.4%, Al2O3 = 10­15% ,T iO2 = 0.5% and C/S = 1.2 for the range of composition studied. Several observations in the iso-fluidity diagrams of blast furnace final slag have shown that liquidus temperature decreased with decreasing MgO content and the viscosity of slag could be regarded as being independent of MgO content in the range of MgO = 5­9% ,A l 2O3 = 15% ,C /S = 1.0­1.2. And, slag fluidity became worse with increasing Al2O3 content under the conditions of MgO = 5.4% ,C /S = 1.2. This study suggested the MgO contents could be lowered from current 6.5 to 5.4% in the conditions of Al2O3 = 15% ,C /S = 1.2 under the stable blast furnace operation with high thermal level. Furthermore, this recipe of lower MgO content (5.4%) had been implemented in CSC’s BF operation to reduce the slag volume, and the formula of fluidity developed in this study had been installed in the process computer of all CSC’s BFs to present slag fluidity in real time.
