Electromagnetic stirring dynamic adjustment method based on molten steel purity

The invention discloses a molten steel purity-based electromagnetic stirring dynamic adjustment method, which comprises the following steps of: judging the purity of molten steel according to the thickness of converter transfer slag and the difference between the content of total aluminum and the content of acid aluminum in the molten steel; dynamically adjusting the argon flow according to the purity of the molten steel; and according to the purity of the molten steel, the stirring current of electromagnetic stirring is dynamically adjusted. The purity of the molten steel is judged according to the converter slag thickness and the aluminum oxide content in the molten steel, and the argon flow and the electromagnetic stirring process are dynamically adjusted according to the purity of the molten steel, so that molten steel inclusions are reduced, and the slab quality is improved. 本发明公开了一种基于钢水纯净度的电磁搅拌动态调整方法，根据转炉中转炉渣的厚度和钢水中全铝和酸铝含量的差值，判断钢水的纯净度；根据所述钢水的纯净度，动态调整氩气流量；根据所述钢水的纯净度，动态调整电磁搅拌的搅拌电流。本发明根据转炉渣厚和钢水中氧化铝含量来判断钢水的
