摘要
从氧化物冶金的观点从发,利用扫描电镜和图像分析仪研究了非调质钢加钛脱氧后钢液中夹杂物的形貌、组成和尺寸分布以及孕育时间对夹杂的影响,并考察了加钛前后钢的组织变化．结果表明：钛的脱氧产物都可成为硫化锰夹杂的形核核心；此类夹杂物呈细小弥散析出,适当的孕育时间可使夹杂细化；加钛后,钢的组织细化．
SEM and image analysis technique were used to investigate the morphology, chemical composition and size distribution of inclusions and the effect of holding time on the size distribution of inclusions in a non-quenched and tempered steel deoxidized by Ti. The results showed that the deoxidation product of Ti in liquid steel could become the nucleus of MnS in solidification of liquid steel. After adding Ti, inclusions in the steel were finely distributed. A proper holding time could make inclusions fine. The grains were fine after adding Ti in the steel.
