| Abstract Scope |
This study focuses on a 500 mm × 2000 mm large aluminum alloy thick plates as the research subject. A coupled fluid flow and heat transfer model for Direct-Chill casting was established to investigate the influence of the bag-shaped diversion device on the thermal-flow transfer behavior. The results show that the width and length of the shunt bag have a significant effect on the flow field, but have no obvious effect on the temperature field inside and on the surface of the ingot. The wider the shunt bag, the outward the flow field direction under the shunt bag, and the width of the shunt bag has a great influence on the narrow-surface vortex. The longer the shunt bag, the less melt flows out from under the shunt bag, the more likely it is to form eddy currents on the edges of the wide surface. |
