钢液中非金属夹杂物的演化经历了一系列过程，包括形核、扩散长大和奥斯特瓦尔德熟化、碰撞长大、较大夹杂物上浮和去除，以及凝固过程中夹杂物的推挤和吞没。所有的演化过程都发生在夹杂物与钢液的界面处。因此，夹杂物与钢液之间的界面性质，如界面能和接触角，对夹杂物的演化起着至关重要的作用，从而决定了夹杂物的特性。为了有效控制夹杂物的特性，基于理论分析和实验结果，系统地综述了界面特性在非金属夹杂物演化过程中的作用。在脱氧的早中期，夹杂物应具有尽可能高的界面能或接触角，以促进夹杂物的去除。但在凝固后期，应尽量降低界面能，以减弱夹杂物的聚集和推挤作用，有利于形成尺寸小、分布均匀的夹杂物。为了优化钢中最常见的Al 2 O 3夹杂物的特性，提出了几种控制策略。
The evolution of non-metallic inclusions in liquid steel involves a series of processes, including nucleation, growth by diffusion and Ostwald ripening, growth by collisions, floating up and removal of relatively large inclusions, as well as pushing and engulfment of remaining inclusions during solidification. All the evolution processes occur uniquely at the interface between inclusions and liquid steel. Therefore, interfacial properties between inclusions and liquid steel, such as interfacial energy and contact angle, play a crucial role in the evolution of inclusions, thus determining the inclusion characteristics. To effectively control the inclusion characteristics, the role of interfacial properties in the evolution processes of non-metallic inclusions is systematically reviewed in this work, based on theoretical analysis and published experimental results. In the early and middle stages of deoxidation, inclusions should have as high interfacial energy or contact angle as possible to enhance inclusion removal. In the later stage, however, the interfacial energy should be decreased as much as possible to weaken the clustering and pushing of inclusions, favoring the formation of small-sized and uniformly-distributed inclusions. To optimize the characteristics of Al 2 O 3 inclusions, which are the most common in steel, several control strategies are proposed.
