| Abstract: | 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 form... |
