摘　　要：介绍了向钢液中引入超细固体颗粒诱发微小气泡去除夹杂物一种工艺方法,并在铝镇静钢生产中进行了试验,结果表明:该方法可以显著降低钢液中非金属夹杂物数量,与传统工艺相比,采用该技术对钢液进行处理后,铸坯中氧化物夹杂的数量明显减少,而且尺寸变小,铸坯的平均w(T.O)可达0.000 7%,有效地提高了钢液的洁净度。This article introduce a removing inclusions process method by fine bubble coming from fine solid in molten steel, and the tests were proceeded in killed carbon steel in steel making plant. The results indicate that it may reduced markedly inclusions in the molten steel. Compared with conventional inclusion removal technology, the number of the oxide inclusion can be decreased to a lower level and the inclusion size be- comes finer. Using this technology, the mass fraction of total oxygen in the as-cast slab can approach to 0. 000 7 %,and the purity of molten steel was improved.
