The ladle shroud is a vital component in the continuous casting process of steelmaking as it supports the production of a wide range of specialty steels. However, it is plagued by a persistent issue of clogging, which not only diminishes the lifetime of the Alumina-Carbon ladle shroud but also severely disrupts the smooth operation of the continuous casting process. Utilizing a numerical simulation technique, the research adopted the method of particle-liquid two-phases coupling, to probe into the clogging mechanism in the ladle shroud from behavior of heat transfer, flow and inclusions. The study indicated that the temperature distribution and flow behavior have a positive effect on the formation of clogging, especially the inclusions. Various factors synergistically contribute on the inner wall, promoting severe clogging at the outlet of the ladle shroud. Finally, a simulation-based clogging mechanism is concluded coupling above factors.

连铸过程中堵塞机制的热分析、流动分析、夹杂物分析


钢包护罩是炼钢连铸过程中的重要组成部分，因为它支持各种特种钢的生产。然而，它受到持续堵塞问题的困扰，这不仅缩短了氧化铝碳钢包护罩的使用寿命，还严重破坏了连铸工艺的顺利运行。利用数值模拟技术，该研究采用颗粒-液体两相耦合的方法，从传热、流动和夹杂物的行为中探究钢包护罩中的堵塞机制。研究表明，温度分布和流动特性对堵塞的形成有积极影响，尤其是夹杂物。各种因素协同作用在内壁上，促进钢包护罩出口处的严重堵塞。最后，得出一种耦合上述因素的基于仿真的堵塞机制。
