近年来对薄板等的质量要求日趋严格，希望尽可能地减少夹杂物数量，特别是在中间包内使钢水净化，对提高产品质量及防止浸入式水口堵塞显得至关重要。中间包除了能够向连铸机各流分配钢水外，还能使夹杂物在中间包内上浮分离，从而使钢水得到净化。但是连铸时由于炉渣卷入以及 In recent years, the quality requirements of sheets and the like have become more and more stringent. It is hoped that the number of inclusions will be reduced as much as possible, especially in the tundish. It is crucial to improve the quality of the products and to prevent plugging of the immersion nozzle. In addition to the tundish can be allocated to the caster flow of molten steel, but also make inclusions in the tundish float up and down, so that the molten steel to be purified. However, due to slag involved in continuous casting as well
