摘要
高炉炉渣中Al2O3含量过高会造成炉渣粘度增高,流动性变差,脱硫能力降低。本次研究通过调整炉渣二元碱度及MgO含量等措施,得出:随着Al2O3含量逐渐升高,硫在渣铁中的分配系数逐渐降低;Mg0含量从9%增加到12%,炉渣脱硫能力逐渐提高,超过12%时,脱硫系数反而降低;二元碱度从1.1增加到1.2过程中,具有最佳脱硫效果的炉渣碱度大约在1.17左右。
The slag viscosity will be increased and the fluidity of slag become bad, and desulphurization capacity will be depressed when the content of Al2O3 in BF slag increased. In this article , with the measurement of adjusting the basicity and the content of MgO in the slag,it can draw a conclusion as follows： the sulfur＇s coefficient of distribution gradual decrease with the increasing of Al2O3 ; it gradualness advanced from 9% to 12% ;the best desulphurization effect of slag is about 1.17 when it increases form 1.1 to 1.2.
