| 摘 要： | 对韶钢转炉钢渣进行高温重构,采用化学萃取、XRD分析、化学分析等检测手段分析重构钢渣中C/S对RO相(MgO.FeO)转变的影响。结果显示:当C/S大于2.3时,高温重构促使钢渣中RO相分离,产生游离氧化镁(f-MgO);当C/S介于1.8～2.3时,钢渣中大部分RO相转变为镁铁尖晶石(MgO.Fe2O3),少数RO相保持稳定;当C/S小于1.8时,钢渣中RO相保持稳定。

| Abstract: | This paper investigates the transformation of RO phase during modification process at high temperature.Chemical analysis,analytical extraction and XRD were used to determine the effect of C/S on the transformation of RO phase.The results show that when the value of C/S is greater than 2.3,RO phase is discomposed to be f-MgO;While the value of C/S is in the range of 1.8~2.3,most of RO phase is transformed to be magnesioferrite,and while the value of C/S is less than 1.8,RO phase remains unchanged. |
