摘要
To study the source of inclusions in casting billets, 10% BaCO3, 10% SrCO3, and 10% La2O3 were used as tracers into the steel ladle, tundish covering flux, and tundish-coating refractories, respectively, during the production of non-oriented silicon steel. The steel and slag samples were taken from the related working procedure, and scanning electron microscopy (SEM) and a microscope were used to analyze the morphology and composition of inclusions. Experimental results show that the large inclusions in non-oriented silicon steel are mainly SiO2, Al2O3, and aluminosilicate, resulting from the protecting slag and secondary oxidation. © All right reserved.
