| 摘 要： | 提出一种基于结晶器内钢水内外复台冷却高效连铸新技术，即在“结晶器内设置内冷却器——U型管”。采用流体力学分析软件FLUENT，分析了内置U型冷却器时结晶器内钢水的流动状态，并与无内置L型管冷却器时结晶器内钢水流动状态作比较，发现内置U型冷却器使结晶器内钢水的流动状况均匀，钢水的冲击深度减轻，有利于钢中夹杂物上浮。

| Abstract: | A new technology of high efficiency concasting based on inner-outer couple cooling of molten steel in a mould has been advanced, that is to set an inner cooling apparatus- U shape pipes in a mould. The flow status of molten steel in mould with inner cooling apparatus is analyzed by using fluid dynamics analysis software FLUENT, and compared with that without inner cooling apparatus. It is found that the inner cooling apparatus- U shape cooling pipes can make molten steel flow with a lower impact depth which is favourable to inclusion in steel floating up. |
