Characteristics and Origin of Inclusions in 409L Stainless Steel During AODLFCC Process

Keywords： 409L stainless steel , 夹杂物 , 特征 , 成因

对409L不锈钢AODLFCC冶炼过程的不同阶段取钢样，利用扫描电镜和能谱仪研究了钢液中夹杂物的类型，并分析了夹杂物的形成原因。结果表明：AOD钢液中夹杂物主要为CaOSiO2Al2O3MgO；LF中夹杂物主要为MgOAl2O3TiOx；中间包中夹杂物主要为MgOAl2O3TiOx和TiN。

The inclusions in the steel samples taken at different stages of AODLFCC process during 409L stainless steelmaking and casting were observed by a scanning electron microscope with an EDS Xray analyzer. The types of inclusions from different stages of the process were analyzed and identified. The inclusions in AOD were mainly CaOSiO2Al2O3MgO compounds, while in LF, it was detected mainly MgOAl2O3TiOx inclusions. Both MgOAl2O3TiOx and TiN inclusions were found in tundish. The origin of the inclusions formed at different stages was also discussed.
