| 摘 要： | 针对1 240 mm×200 mm板坯连铸提出了一种钢水内外复合冷却技术，即在结晶器内设置内冷却器 U形管，起到提高传热效率改善铸坯内部组织之目的。运用流体力学分析软件，就内外复合冷却结晶器内钢水在流场温度场耦合作用下的凝固状况进行数值模拟，发现内冷却器可以使钢水的流动状态均匀和加快连铸坯的凝固速度。

| Abstract: | Inner outer couple cooling technology of molten steel for 1 240 mm×200 mm slab continuous casting is put forward in order to enhance the efficiency of heat transfer and improve inner structure of billet, in which an inner cooling apparatus U shape pipe is set in the mold. Solidification state of molten steel under the coupling condition of flow field and temperature field in inner outer couple cooling mold is simulated by using fluid dynamics software. It is found that inner cooling apparatus can make molten steel flow even, which is favourable to the floating of inclusion in molten steel, increase the solidification rate of billet and improves the quality of billet. |
