| 摘 要： | 1.IntroductionDuring the process of continuous casting, the molten steel flow affects directly the temperature dis-tribution, the speed of heat transfer, the non-metallic inclusion ascending and the uniformity of tempera-ture and chemical component in the mould, which is directly related to the internal and surface quality of casting blank. So it is meaningful to study the molten steel flow in different conditions of SEN parame-ters and shape.Recent years, with the development of computer and…

| Abstract: | According to turbulent theory and characteristics of beam blank continuous casting, 3-D model to represent the flow of beam blank mould is established. The predicted results indicate that the exit obliquity of up 15°(+15°) should be adopted, which will benefit the floatation of non-metallic inclusion and purification of the molten steel. When the nozzle angle is 120°, the flow pattern is reasonable. Proper nozzle depth can be 200ram. Turbulent kinetic of meniscus can be reduced by adopting the square nozzle and suitable area of side outlet when casting speed increases. The results are consistent with those of water model experiment, so the model is exact and reasonable. The model can provide important information for design of SEN and defining of immersion depth. |
