| 摘 要： | 了解钢从液态到固态的转变是连铸最基础的方面,然而它还是一个很多问题尚未解决的复杂课题。论述了结晶器操作导致皮下缺陷的形成,包括钢液在弯月面凝固、表面能和界面能变化、气泡的影响以及钢液与液渣界面的动力学现象。

| Abstract: | Understanding the transformation of liquid steel to solid steel is the most fundamental aspect of continuous casting;however,it remains a complex subject with a number of unresolved issues.In this paper,the following aspects of mold operation which give rise to sub-surface defects will be discussed:meniscus solidification,surface and interfacial energies,effects of gas bubbles,and the dynamic nature of the liquid slag-liquid steel interface. |
