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.

Continuous Casting Billet

The temperature field of continuous casting billet (CC-billet) is important to carry out the research on direct rolling of free-heating (DROF). The solidification and the heat transfer process of CC-billet from crystallizer to cutting point were studied by finite element method (FEM).The casting speed was improved in order to get reasonable temperature field during DROF.

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.

Crystallizer steel belt feeding technology make use of melt’s fusion decalescence, controlling the distribution of melt temperature field, restrain the columnar crystal’s growing to eliminate the composition segregation and internal loose of continuous casting. And it will improve the continuous casting’s quality. By discussing the effect of casting speed, the size of steel, casting section and other factors on the steel belt feeding speed, making comparison of different casting section get strip suitable feeding speed and range of strip size, combining with a steel for steel strip feeding test mold, its theoretical and practical production results the basic agreement

Uniform Temperature Field

Wide plates are mainly prepared through traditional cold mold continuous casting technology. A problem is cracking which caused by the non-uniform temperature field in solidification. Warm mold continuous casting is a new technology. Warm mold continuous casting of wide copper plate (section 500mm×12mm) was studies. Temperature field, solid/liquid interface and microstructure were analyzed by ProCAST software. By simulation, the optimal processing parameters: withdrawing speed was 60-80 mm/min, and the temperature of copper melt, mold and cooling water were 1200°C, 800-900oC and 20 oC, respectively. The temperature field in the width direction of the copper plate broad face was uniform, and the temperature decreased uniformly along the withdrawing direction. The temperature difference between center and edge was within 10 oC, and the temperature difference between narrow and broadfaces was within 25oC. Microstructure of plate contained ‘bamboo-like’ grains along the withdrawing direction.
