摘　　要：为探讨高炉渣排碱、脱硫能力间的关系,根据广钢实际高炉渣成分,通过实验研究了w(CaO)/w(SiO2),w(MgO),w(Al2O3)对炉渣排碱、脱硫的影响.结果表明:w(CaO)/w(SiO2)对炉渣的排碱、脱硫能力影响较大,二者相互矛盾;w(MgO)升高,炉渣排碱能力降低,含碱炉渣最佳脱硫对应的w(MgO)比普通炉渣低3%.w(Al2O3)升高,炉渣的排碱能力变化不大,而脱硫能力迅速降低.广钢高炉适宜的炉渣成分为:w(CaO)/w(SiO2)保持在1.0,w(MgO)保持在12%,w(Al2O3)保持在15%.Investigates experimentally the relationship between dealkalization and desulphurization of alkaliferous BF slag. The influences of w （CaO）/w （ SiO2 ）, w （MgO） and w（Al2O3） on the two removabilities are studied according to the actual BF slag composition of GuangSteel. The results reveal that w （CaO）/w （SiO2） has great influence on both the two removabilities and they contradict each other. The dealkalizing rate falls with rising w （MgO）, and the w （MgO） corresponding to best desulphurizing rate on alkaliferour slag is 3 % lower than on normal slag. The change of dealkalizing rate is little but the desulphurizing rate decreases rapidly with rising w（Al2O3）. For the sample slag appropriate composition is that the w（CaO）/ w（SiO2） shall be kept 1.0, with w（MgO） 12% and w（Al2O3） 15%.
