Abstract Scope |
A three-dimensional model with multiphase flow field, transient heat transfer and solidification, inclusions flow during round steel billet continuous casting in the mold was established using ANSYS Fluent software. A code was also written to analysis solidification shell thickness and inclusions capture by Python. The influence of casting speed, casting temperature, nozzle immersion depth, and inclusions size on the thickness of the solidified shell and the movement of inclusions were investigated. The results show that due to the influence of the molten steel flow field at outlet of the immersion nozzle, two circulation zones are formed. One is formed directly below the immersion nozzle. The other is in the upper half of the mold and center position of the circulation zone changes over time, which causing uneven solidification. Assuming the inclusions size distribution is 1~250 μm, only about 10.8% of the inclusions will float to the slag layer. |
