摘要
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.
