选用国内外无取向硅钢标杆企业A、B、C的产品,采用非水溶液电解提取+SEM(EDS)方法,分析了其典型牌号对应成品试样中的夹杂物.结果表明,从磁性能控制角度而言,受钢的化学成分及生产工艺影响,A、B、C企业成品试样的夹杂物尺寸、种类、数量存在差异,这些差异对其磁性能产生显著影响;从夹杂物控制角度而言,A、B、C企业对应成品试样的夹杂物,以MnS、CuxS复合或者AlN、MnS、CuxS复合为主,其中1.0μm以下的夹杂物数量分别为2.34×107个/mm3、2.98×107个/mm3和11.98×107个/mm3,1.0μm以上夹杂物数量均很少,夹杂物的平均尺寸从大到小依次为A企业、B企业、C企业.

According to the production of three benchmarking manufacture enterprises A, B and C of non-oriented silicon steel at home and abroad, the inclusions in finished steel samples with typi-cal grades were investigated by electrolytic extraction from non-aqueous solution and SEM(EDS). Results show that, from the viewpoint of improving the magnetic properties, affected by chemical composition and production technique, the size, type and amount of inclusions in finished steel samples are various, which will affect the magnetic properties significantly. From the viewpoint of controlling inclusions in finished steel samples, the mainly inclusions are the combination of MnS and CuxS or the combination of AlN, MnS and CuxS. The amounts of inclusions with size below 1.0 μm in steel samples of enterprises A, B and C are respectively 2.34×107/mm3, 2.98×107/mm3 and 11.98×107/mm3, meanwhile, there are few inclusions with size above 1.0 μm in the samples. The order of average size of inclusions produced by the three enterprises is A>B>C.
