一、前言众所周知,弧型连注机浇铸的铸坯,由于夹杂物在接近铸坯内弧侧表层的聚集,降低了连铸方坯的内部质量。为了减小冲击深度,防止夹杂物的聚集,已设计出了浸入式水口。然而,由于钢水的侵蚀和操作条件的限制,水口的形状易于改变。因此,为容易地得到高质量的方坯,研制并试验了用电磁搅拌器促使钢水流动的方法。 First, the preamble As we all know, curved continuous casting machine casting slab, due to inclusions in the arc near the slab surface layer of the aggregate, reducing the continuous casting billet internal quality. In order to reduce the impact depth, to prevent the accumulation of inclusions, has designed the immersion nozzle. However, due to the erosion of molten steel and operating conditions, the shape of the nozzle can easily be changed. Therefore, in order to easily obtain a high-quality billet, a method of using a magnetic stirrer to promote the flow of molten steel was developed and tested.
