Numerical Simulation of Flow of Liquid in Molten Pool of Twin-roll Casting Rolling 5182 Aluminum Alloy Strip

The shape and the flow state of the liquid surface in molten aluminumAluminum have an important impact on the castingCasting and rollingRolling process of aluminum alloysAluminum alloys. Mathematical models of flow of liquid in twin-roll castingTwin-roll casting and rollingRolling of 5182 aluminum alloyAluminum alloys strip was establishedEstablished in this paper. The influence of different nozzle structures of distributors on the shape and the flow state of liquid in the molten pool was studied by numerical simulationNumerical simulation. The results show that changes in the inclination of the nozzle of the distributor, the height of the nozzle, and the depth of the distributor into the molten pool will affect the flow of liquid in the molten pool. With the increase of the depth of the distributor into the molten pool, the shape of liquid surface in the molten pool changes obviously, and the turbulent kinetic energy of the liquid surface in the molten pool decreases. The reasonable structural parameters of the distributor nozzle were obtained through research.
