【摘要】根据实际生产条件,用FactSageTM计算了钢液中w([O]平衡)和w([Al]平衡)分别为:10×10-6和(5~10)×10-6。以此为基础,计算了0~1000s,计算了夹杂物的粒度分布和总数。计算结果和实验基本吻合。最后,提出了进一步完善模型的方法。更多还原

【Abstract】 Based on production conditions, using the FactSage^TM software, the balance figures of Al-O in 1 600 are calculated, and w(\[O\]_balance)=1010^-6, w(\_balance)=（510）10^-6. According to this balance value, during 01 000 s, the size distribution of Al₂O₃inclusion is calculated. The calculating results roughly agree with experimental measurements. In addition, the future developing of the model is discussed.更多还原
