提出了一种夹杂物控制技术——反应诱发微小异相净化钢水技术,采用转盘造粒工艺制备了具有该种功能的复合球体,并在RH精炼后期加入上述球体进行工业现场试验.结果表明:反应诱发微小异相净化钢水技术是一种成本低、效率高且简便易行的夹杂物控制技术,它可以短时间(大约10min)内显著降低钢液中的非金属夹杂物的数量;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,尺寸变小,铸坯的平均全氧T[O]最低可达6×10-6,吨钢成本可降低5～10元.
An inclusion control technology was proposed based on the reaction-induced microstructure and microstructure of molten steel, and the spherical composite ball with this kind of function was prepared by using the turntable granulation process. The field test was carried out by adding the above- Reaction-induced micro-phase purification of molten steel is a low-cost, high efficiency and simple and convenient inclusion control technology, which can significantly reduce the number of non-metallic inclusions in molten steel in a short period of time (about 10min) Compared with the technology, after using the technology to treat the liquid steel, the amount of oxide inclusions in the slab obviously decreases and the size becomes smaller, and the average total oxygen content T [O] of the slab reaches a minimum of 6 × 10-6, Cost can be reduced 5 to 10 yuan.
