结合工业化生产的无取向硅钢,采用非水溶液电解+扫描电镜观察方法,探讨了化学成分体系对夹杂物控制的影响。结果表明,随着Si、Al元素含量升高,氧化物夹杂数量明显减少。氮化物夹杂数量先是快速增多、而后逐渐减少。与此同时,夹杂物平均尺寸逐渐变大。低铝状态下,硫化物夹杂数量较多;高铝状态下,硫化物夹杂数量明显减少,而且CuxS夹杂消失。高硅低铝系列钢、中硅低铝系列钢、低硅无铝系列钢、高硅高铝系列钢夹杂物数量依次减少。 Combined with industrialized production of non-oriented silicon steel, non-aqueous solution electrolysis + scanning electron microscopy was used to investigate the influence of chemical composition on the inclusion control. The results show that with the increase of Si and Al contents, the amount of oxide inclusions decreases obviously. The amount of nitride inclusions first increased rapidly and then decreased gradually. At the same time, the average inclusion size becomes larger. Under the condition of low aluminum, the amount of sulfide inclusions is more; under the condition of high aluminum, the amount of sulfide inclusions obviously decreases, and the inclusions of CuxS disappear. High-silicon low-aluminum series of steel, low-silicon series of silicon, low-silicon aluminum-free series of steel, high-silicon high-aluminum series of steel inclusions in order to reduce the number.
