Study on solidification of round billet horizontal continuous casting and quality of casting blank

The temperature distribution and solidification heat transfer process of round billet in different drawing blank technics were studied by means of solidification/melting models of Fluent software and pin shooting jointly, taking round billet horizontal continuous casting process as the research object. By this studies, the liquid steel temperature field distribution in the mold was obtained, and effects of casting process on steel temperature field inside of the mold was achieved. The results show that, through nailing experiment and numerical simulation using Fluent software, the solidification heat transfer model can be established, liquid solidification in continuous casting steel heat transfer process can be effectively analyzed, and the quality of molten steel can be improved.
