本发明提供一种超低铝无取向硅钢夹杂物控制方法。该钢种化学成分质量百分比为C≤0.005％，Si：0.25％‑1.50％，Mn：0.15％‑0.55％，P：0.02％‑0.06％，S≤0.005％，Als≤0.005％，余量为Fe及不可避免的杂质。工艺流程为：KR→BOF→RH→连铸。转炉出钢严格控制下渣量，出钢结束加石灰、渣面脱氧剂调渣；RH脱碳结束后，先加低碳低硫硅铁、金属铝或铝钙铁合金复合脱氧，最后加入金属锰、磷铁进行合金化，然后净循环6‑10min，破空出钢运至连铸浇注。得到钢水中主要为SiO2‑Al2O3系夹杂，避免了生成低熔点SiO2‑MnO系夹杂，轧制延展变长，影响晶粒长大；同时也避免了生成高SiO2组分类酸性夹杂，导致耐材的侵蚀。可显著改善钢中非金属夹杂物类型，提高无取向硅钢的性能，并提高了钢水浇注性能。
