| 摘 要： | 随着对钢质量要求的不断提高，对钢液中非金属夹杂物去除也提出了更高的要求。碰撞、长大是去除钢液中小粒径夹杂物的有效方法。针对钢液中非金属夹杂物碰撞、长大的最新研究，分析了不同碰撞机制下，非金属夹杂物的碰撞、长大情况，探讨了钢液中非金属夹杂物碰撞团聚的机制。数值模拟是研究钢液中非金属夹杂物碰撞、长大的一个重要方向。结合相关研究的最新进展，展望了今后的发展趋势。

| Abstract: | With the improvement of steel quality demand,the removal of non-metallic inclusions in liquid steel should satisfy much higher requirements.Collision and growth of inclusions in steel is effective method for small diameter inclusion removal.Under different collision condition,non-metallic inclusion in liquid steel collision and growth were summarized with related study.Mechanism of agglomeration of non-metallic inclusions in liquid steel was analyzed.Numerical simulation was a promising method to study the collision and aggregation of non-metallic inclusions.Besides,the perspective on development of non-metallic inclusions collision and growth in steel was given combined with latest research progress. |
