Abstract: In this paper, the continuous casting process of the non-oriented electrical Si-steel from a domestic steel company was taken as a research subject. Through sampling from tundish and continuous casting slab followed by oxygen and nitrogen analysis and bulk sample electrolysis, the content change of oxygen and nitrogen and the change of content, scale, type and source of large-size non-metallic inclusions was systematically studied. Under the experiment conditions of this paper, the main conclusions are as follows. The content of w(T.[O]) and w([N]) in the head slab and the molten steel of the corresponding tundish was significantly higher than the one in the other casting state. During different casting states, the content of [N] in the slab was lower than the molten steel of the corresponding tundish. The re-oxidation by air in the continuous casting process was serious. The large-size inclusions in the slab were formed by slag entrapment and refractory material erosion. The flow field of tundish and continuous casting mold should be further optimized.
