| 摘 要： | 为判断铸坯中夹杂物的主要来源,在无取向硅钢生产过程中,向钢包、中包覆盖剂及中包表面耐材中分别加入基体重量的10% BaCO3,10% SrCO3,10% La2 O3(质量分数)作为示踪剂,并在相关工序取钢样或渣样,利用扫描电镜和显微镜观察分析夹杂物的形貌和成分。研究表明,无取向硅钢中大型夹杂物主要为SiO2、Al2 O3以及硅铝酸盐,夹杂物的主要来源是保护渣卷入和二次氧化。

| 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. |
