摘要
Abstract
To study the source of inclusions in casting billets, 10% BaCO3 , 10% SrCO3 , and 10% La2 O3 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 mi-croscope 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 , Al2 O3 , and aluminosilicate, resulting from the protecting slag and secondary oxidation.关键词
