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%.

Abstract: 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%.
