Abstract: In the paper a inner-outer couple cooling technology of molten steel for 1240×200mm slab continuous casting, that is to set an inner cooler-U shape pipes in the mold, is put forward in order to enhance the efficiency of transmitting heat and improve the flow status of molten steel. The flow status of molten steel in inner-outer couple cooling mold is simulated by using fluid dynamics software. It is found that setting inner cooler in the mold can make molten steel flow status even, which partly act as electromagnetic trig and is favorable to inclusion in molten steel floating up.

Abstract: In the paper, flow status and solidification status of molten steel in inner-outer couple cooling mold in the filling process are simulated by using fluid dynamics software Flow-3d, and obtain distributing diagrams of flow field and temperature field and free-surface shape diagrams in the filling process. Influences of flow field and temperature field of filling process on solidification are analyzed in the slab continuous casting. It is indicated that inner cooler can improve molten steel flow status, which is favorable to inclusion in molten steel floating up, quicken the solidification rate of molten steel in the mold.

Abstract: There is a new idea on the billet casting Q235 with size of 165mm×165 mm,It involves a couple technology to cool molten steel both from inside and outside, namely: to emplace an inner cooler -a pipe with the shape of letter U in the mould. It aims to increase the thermal conductivity and improve the inner structure of the billet. With the help of Fluent -a kind of CFD business soft ware, a numerical simulation is undertaken to testify the condition of the molten steel in the inner-outer cooling mould coupled by flow field and temperature field.

Abstract: An inner-outer coupled cooling technology of molten steel for 1240×200mm slab continuous casting, that is to set an inner cooler—U shape pipes in the mold, is put forward in order to enhance the efficiency of transmitting heat and improve inner structure of billet. The flow status and solidification status of molten steel under coupling flow field and temperature field in inner-outer coupled cooling mold are simulated by using fluid dynamics software, and compare with those in traditional mold. It is found that setting inner cooler in the mold can make molten steel flow status even, which is favorable to floating up of the inclusion, quickening the solidification of steel liquid and improving the quality of billet.
